I’ve been cycling for around 12 years and I’ve never seen such a scam in terms of bikes notice how she says make sure there’s no contamination and yet the whole brake unit is so much closer to the ground where most of the dirt is. The battle for disc brakes just isn’t worth it save your and selfs get rim brakes!!!!!!
@@tomlawless4406 Sorry sir but nope,, although the rim brakes are all further from the ground, the dirt from the ground will contaminate the rim, and rim will contaminate the break pads that are as you said further from the ground.
@@cyclemaintenanceacademy The detailed info has helped me with some procedures I was missing. We assume that everyone knows the basics, but that is not necessarily so. :-)
Thank you, your video is fantastic advice - After searching numerous videos that talk endlessly about everything and anything and finally get to brakes, your video was outstanding
Thank you so much for the kind words! I'm really glad the video was able to cut to the chase and give you exactly what you were looking for. It's awesome to hear it stood out among all the others-happy to help, and enjoy your smoother braking setup! 🚴🙂
Thanks CMA ! Another helpful video - i love how you explain things step-by-step and don't assume viewers already know stuff - tho at the same time i never feel 'talked down to' in your videos. Hope you might also be doing one on squeaky rim brakes ?
Every time I replace the pads, I clean the brakes and pistons and make sure they are all moving equally. I also loosen the two bolts holding the brake to the bike or arch, squeeze the brake, and then retighten the bolts. It's fast and easy and seems to recenter the brake with the new pads.
Hi thank you so much for this very well organized and logical video. It made a lot of sense. I have a mtb and my rear brake squeaks only when I’m riding. Not when I’m braking. What’s weird is that when I hold the brake with a bit of pressure the squeaking stops. I just had the brake pads replaced too. I didn’t know about baking them in. What do you think might be going on? Any help would be very much appreciated.
Hi Chris, thanks for your comment and I am so pleased that you found the video useful. Great to see your question and I hope I will be able to help. First I just want to explain to you a bit about the squeaky noise you hear. Whether this is a disc brake or rim brake, each time the pads hit the rim or the rotor they create vibrations. These vibrations make the air molecules vibrate around the brake and then travel. If the vibrations are strong enough they travel all the way to our ears. We receive them as a squeaky sound. Luckily most of the time these vibrations/sounds are not frequent enough to be picked up by us. So, what we need to do is to minimise vibrations generated by your brakes. If contamination is not a problem and the brakes make a noise when you are not using them then most likely your caliper is not centred and the rotor is hitting on one of the pads or even scraping on the inner surface of the caliper. Try this: - Have a look at your rotor and caliper. See if the gaps between each side of the rotor and pads are even and if the caliper sits straight with the rotor. If not then re-centre the caliper. - spin the wheel and see if your rotor is bent. One piece rotors (made out of one piece of stainless steel) are more affected to bend while used. If yours is bent then you can straighten it at the point where it touches the pad. If you don't have a tool you can use an adjustable spanner. If you think that it is bent too much or in too many places you may want to replace it. In this case consider buying a two piece rotor. They tend to be more bend resistant and disperse the heat better. I hope this helps. If you still struggle or have any other questions feel free to get in touch with us. Arek
Oh, thanks so much! I hope to fix my squeal tomorrow. I only have country roads with some steep hills to ride on. My brakes get used way too much! Heavy ebike, it likes to run away. 🚲😳
Great video. One last thing to try is using antisqueal compound on rotor. It basically sands friction surfaces. Replacing rotors and pads for noise is for QUITTERS!
You're very welcome! I'm so glad the video helped clear things up for you. If you ever need more tips or run into other bike maintenance questions, feel free to reach out. 🙂
You're not alone, that mistake is more common than you'd think! Oil on brake pads can really mess with their performance, causing squealing and poor stopping power. It's great to hear the video helped you out! In the future, it's best to keep oil or grease away from the braking surfaces entirely. If the pads are contaminated, you will need to replace them. Glad you got it sorted!🙂
Thanks Andy. Swear "as much"? I think I've managed to totally avoid it! So pleased you're enjoying the vids. I hope they'll be useful when you're training people.
I've had problems with road disc bikes. Currently i have a hydrolic brake bike that screeches and vibrates alot under braking , this is after putting on new discs and pads ,not sure if i bed them in as you described. So I'll give it one last try. My current bike is rim brake and is soooooo much less maintenance.
Hi, and thanks for sharing your experience. Sorry to hear about the issues you're experiencing with your disc brakes. It sounds frustrating, especially after installing new discs and pads. Properly bedding in the pads can definitely make a difference in brake performance, so it might be worth giving that a try. Let me know if you managed to resolve this and if you have any more questions or need further assistance, feel free to ask!🙂
@cyclemaintenanceacademy hi, I've now got a bike with brakes that finally work . Thanks for the tips . It required new discs and pads and brake fluid , but the bedding in process helped with the re centering of the calipers. Thanks again. Was ready to bin the bike 😁😁
Great video! One thing, I'd add is to avoid spraying lubricant or cleaning product around the rotor, as it causes that contamination you mentioned in the first place. Instead, spray your product on a fabric and apply it that way.
Listening to commentary and effects mics on most of the Cobbled and Ardenne Classics and GTs most pros bikes squeal on hard braking and the commentators remark on it so I am not going to spend hours on all kinds of supposed hacks to get rid of it. Acceptance is the key !
Wow. First channel that doesn't just tell the same as everyone else. The obvious. They even disprove many of the common tips with argumentation as to why the tips will never work and in what situation. I was so sure I had contaminated the set and have changed them three times now! It is quickly becoming a reason for me to stop using discs. But the glassing issue I have never heard of, so this is probably what is happening since I was sure oil was not an issue because I even changed the caliber once.
Very good video, disc brakes can be a real pain and on my road bike having tried everything you suggested I ended up having to change discs and pads before having to change the calipers as well. The cost is ridiculous for the limited improvement over rim brakes on the road. I will not buy another road bike with disc brakes again if I can avoid it. MTB is a different story, rim brakes are useless off road and for some reason disc brakes on MTBs seem to be more reliable 🤔
Hi Stuart, glad you found it useful🙏. Hopefully your brake is working like a dream now😉. I appreciate that you've shared your opinion with us about disc brakes on road bikes, it's an interesting topic. In February I am planning to start a weekly livestream to talk about bike related topics and this sounds like a great one to discuss👌. Hope you can find time to join us in the conversation😎. I will be posting more details soon so make sure to subscribe so you don't miss it🙂. Take care
In my case, one or the other method works fine for the rear brake. However, I can't get rid off the noise for my front brake. I have done all mentioned in the video except changing the caliper itself, I don't see any oil leak though. I have been riding for more than a year with rear brake only to avoid noise at the front, which reduces efficient stopping. Only when I change the brake pads with new thick ones, the noise goes down, but after a little while they all start squeaking. Really annoying.
Finally I replaced the entire brake with a brand new one and the noise disappeared. It means there was an invisible leak of oil from the lever to the caliper. Such a relief.
That's fantastic to hear! I'm glad the video has prepared you to tackle the diagnosis. If you run into any questions or need further assistance while working on it, feel free to ask. Happy diagnosing, and I hope you get that squeaky noise sorted out! 🚴♂️🔧
You are a true hero!😎 Guidelines are great because they keep everyone on the safe side - you and the manufacturers. Bike parts manufacturers like Shimano test their brakes (or, like food manufacturers, test their food to check if it's fresh up to the date they mention). Now, sure, your brakes will probably be fine even after just 10 tries, or those sausages might still be good a couple of days past the "best by" date. But that's where the manufacturer can't promise the brake pads will evenly transfer enough material onto the rotor or guarantee your stomach won't regret those sausages!😨 (By all means I've had sausages a few days past their "best by date," and surprisingly, they still tasted pretty good! 😂).
Hi, and thanks for your question. I'm pleased that you liked the video. To remove the glaze from the pads, all you need is fine-grit sandpaper. I recommend using 120 grit or lower for best results. Let me know if you have any more questions or need further advice.🙂
Disc brakes on a road bike are a nightmare - have tried all the above - MTB bike on the other hand works with no problem - didn't need to bed in, or any additional cleaning of the pad and rotors. Have now upgraded the road bike to Shimano dura-ace which has an increased clearance between pad and rotor - these seem to be working OK at the moment. Does leave the question as to whether the design of the road bike set up is flawed.
Hi, thanks for the comment and for sharing your experience with others. Sorry to hear that you had so much trouble with the disc brakes on your road bike. I hope that the new Dura-Ace brakes will finally put an end to your problem, allowing you to enjoy noise-free rides.🙂🚲
Hello, I have bought a NEW eBike and has now 50km. I realised that when braking harder, it makes the gurgling sound like bubbling! What is the problem and what should I do? Thanks for the advice in advance!
Hi, and thanks for your question. First of all, congratulations on your new e-bike. Regarding the problem with your brake, I would love to help but it's a bit tricky to offer the correct advice without seeing the bike. Can you take it to the shop that you bought it from? I hope you will sort this out soon. If you find out what the problem was feel free to share it with us. Good luck👍
Hi, thank you for your question, and apologies for not being able to get back to you sooner. While 905 thinner (a type of solvent typically used for cleaning and degreasing) can be used to clean certain surfaces, it's generally not the best option for cleaning bike brake pads, especially when compared to isopropyl alcohol. Isopropyl alcohol is widely recommended because it's a safe, effective, and gentle cleaning agent that removes oils, dirt, and contaminants without damaging the material of brake pads. It evaporates quickly, leaving no residue, and is specifically safe for use on brake components. 905 thinner, on the other hand, is a stronger solvent and could potentially damage the brake pads or leave harmful residues that might affect braking performance. It is often used for tougher cleaning jobs (such as degreasing or cleaning metal parts) and might be too harsh for brake pads that need to maintain their grip and integrity. If you’re looking to clean your pads, I’d strongly suggest sticking with isopropyl alcohol to avoid compromising the braking system's performance and safety.
You can also have brake noise from a sticky piston. Usually in this case the noise will be when you release the lever. The sticky piston does not retract fully and therefore your pads will be dragging on the rotor. The solution to this is to rebuild the caliper and make sure the pistons are not damaged. For less expensive brakes I think it's probably easier just to buy a new caliper.
Hey, thanks for clarifying this problem and explaining the solution! It's really helpful for other viewers to know about the sticky piston issue and how it can cause noise. Appreciate the insight!🙂
Great video and helpful, I’m not sure if my braking issue fits these issues. I just bought my Gravel bike back in July and probably have under 300 miles on it and my front disc brakes squeaks when I break. I can’t imagine the pads are worn or the rotor is bad. What do you think it could be?
Hi Joseph, thanks for your comment. Yes, it's a tricky one. What I can recommend first is to check if your caliper is aligned with the rotor. We made a video on how to do this, you can watch it here: ua-cam.com/video/J8OsyIOovbA/v-deo.html Also, check if all the bolts on the rotor are tightened. Did you bed in the pads? If not then it would be a good time to do this. If you tried all of these and your brakes are still squeaking then it will be good to try and replace the pads and rotor to eliminate the contamination issue. I hope this helps. Let us know how you got on.
so on my new bike one of the brakes started Squeaking and it sounds uneven cleaned it and nothing and the disc is strait and the other things seem fine to so going to have it serviced
hi, sorry to hear about the squeaking brake on your new bike! It can be frustrating when issues like that arise, especially with new equipment. Having it serviced is a great idea, as a professional can help identify the problem and ensure everything is working properly. i hope they've managed to sort it out for you!
Hi, and thanks for your question. It's a tricky one. You will find a variety of answers online and it really depends on your preferences. I use middle grit sandpaper myself.
Hi Lucian, thanks for your comment and I'm pleased that you enjoyed our video. Glad to hear that the combination of these components work for you. Did you try any other mixture of differnt brand rotors and pads to compare?
@@cyclemaintenanceacademy Yes, on my gravel/trekking bike I did pair RD 7120 SLX rear derailleur with 11 46 xt cassette 11, R8000 dual chain ring crankset and 11 speed XT shifter. I would have got RD8120 but couldn't find it at the right price. I did this because there are no 11 speed rear derailleurs that work with dual chainring crankset and 11 46 cassette, only 11 42. Limited by design... But 7120 or 8120 12 speed derailleurs work with 11 speed systems in this scenario.
Hi, thanks for sharing your experience and I'm glad this method worked for you. However using a wash up liquid on disc brake poads is niot recommended. While it may seem like a quick and easy cleaning solution, it can leave residues that may negatively affect the performance of the brakes. Dish soap is formulated to break down grease and oils, but it can also leave a slippery film, which could lead to poor braking performance, reduced friction, and even noise when the brakes are applied. For cleaning disc brake pads, it's better to use isopropyl alcohol or specific brake cleaner products designed for this purpose. These cleaners are formulated to evaporate quickly and leave no residue, which ensures that your braking surfaces are free of contaminants and function as intended.
is it advisable to sand down rotor disc? i have seen some videos here on youtube where they sand the rotor but did not try it because i might regret it later..
Hi Jonathan, thanks for your question. It's a tricky one and yes the vast amount of videos can be confusing and you're given conflicting information. Firstly let's see why some videos advise to sand down rotors (as this is usually not explained). So, the rotor does not get contaminated like pads. Sanding pads can potentially remove a layer of contamination (if you're quick enough). Rotors have a layer of pad transferred during the bedding in procedure. If that procedure is not done properly then an uneven layer of pad is transferred and this can cause vibration, which we hear as a squeaky noise. Only then sanding the rotors can potentially make a difference. It's hard to say whether this is causing the problem as the layer transferred is microscopical and not visible to a human eye. We do not sand rotors for our customers, for the price of a new one we just fit a replacement. However I understand that you may want to try it if no other solution works. First make sure that your rotor is spotless. Especially the edges of the holes on the rotor can collect contaminated dirt that can be transferred back onto newly fitted pads. I leave the decision to you. Let me know your thoughts and if you decide to go ahead and sand them, share your results with me and other viewers🙂
Sorry for the delayed response! I would advise that if the oil has been left on the pads for too long, it can definitely affect their performance and cause contamination, making them less effective. Ideally, oil should be cleaned off immediately to avoid damaging the pads. However, since it's been a while since your comment, I'd love to know if you've been able to fix the issue! Let me know how it turned out.
Hi, and thanks for your questions. Yes, that's possible as well. First try to bed in your brake pads. That's the most common reason why the brakes make squealy noise on a new bike. Let me know how you got on and if the squaky noise is gone.
Hey, yes, you can buy any rotor as long as it is compatible. We made a great video here to help you understand the differences between the rotors and how to choose the correct replacement. ua-cam.com/video/FJiL92Su688/v-deo.html Let me know if it's helpful.
1:07 => That´s EXACTLY my noise problem, that I have for years now !!! SM RT86 rotors with Saint M820 brakes. I tried the following organic pads: DS03S, Kool stop, BBB, Cube. The Kool stop were silent when they were new, but loud in the end, too. All other pads were loud all the time (especially in humid conditions). I love my bikes and I maintain them neurotically. I only have that problem on my Haibike FS RC 26 pedelec. Not on my recumbents or my E-Scooter. Does anyone have advice for me (speaking from experience with my above mentioned setup) ?
Hi, and thanks for your comment. I understand your frustration but don't throw in the towel just yet! Replace both the brake pads and the rotor with new ones, and bed in the pads. This will most likely do the trick. I hope this helps and let me know how you got on?
@@cyclemaintenanceacademy I cleaned the discs (also the cut out holes !) and the pads (on the inside) with acohol, filed the pads a bit down on the inside with a key file and then broke in the pads (20-30 times braking from 25km/h down to 15 km/h). The noise was gone after that :) It seems, that since I have more than one bicycle, I tend to neglect some things here and there ;_)
Hi Steve. Thanks for your question. The caliper may not be set up correctly. It sounds like your rotor continuously rub on one of the pads and it stops when the pads are compressed. Try to adjust the caliper so that the rotor sits evenly between the pads. We have a video on our channel on how to adjust disc brake pads. Let me know if this was of any help.
Hi, and thanks for your question. Because there is a very small amount of lubricant in water brakes can sometimes squeak in the rain. This should stop when they dry out. I hope this helps.🙂
Hi, and thanks for your question. I imagine you are looking for a type of disc brake pads that will fit on your brake. The best way is to check the brand and model number of the brake and type this into googe (for example: Shimano Deore BR-M6100). If you have Shimano brakes and are not sure where to find a unique model number you can check my video here for guidance: ua-cam.com/video/9Mqx8qwKiHk/v-deo.html Alternatively you can remove your old brake pads and take them to your local bike shop. They will be more than happy to sell you the correct replacement. If you're not sure how to remove the pads watch my video tutorial here: ua-cam.com/video/3dhj5qmWh54/v-deo.html Let me know if this was helpful and if you managed to source the correct repacement brake pads.
Hi Jack, thanks for reaching out with your question. It might be that the rotor has not been cleaned thoroughly (which we all know is tough to clean because you have to reach between all these little holes). Even if you put in new pads, the oily residue from the rotor can still be transferred to the surface of the new pads and contaminate them. Another possibility is that if the pads haven't been properly bedded in, an uneven layer from the pads could have transferred onto the rotor's surface, causing vibrations and that squeaky sound you're hearing. You can try either thoroughly cleaning the rotor before fitting new pads or fitting both a new rotor and new pads and properly bedding them in. This should help eliminate any contamination or unevenness and hopefully solve the squeaking issue. Give it a try and let me know how it goes. Good luck!
You're very welcome! I'm so glad to hear your brakes are working great now. Thanks for the feedback! If you run into any other issues, feel free to ask. 😊
Hey Niraj, thanks for your comment and for sharing your experience with others. Great that this method worked for you for a few hours however wash-up liquid is made of detergents that can be absorbed by disc brake pads. This will contaminate them causing squeaking and reducing braking power. I hope this helps🙂
Hey, thansk for your question. It depends. If the liquid he used had contaminate the pads then you may need new pads and clean or replace disc rotor. I hope this helps
Take any type of tree leaves. Then rub tree leaves in your disc. Sound will gone. First 4, 5 time breake will work like 50%,, then it will be all fine. Giving advise with experience,, i ride daily 100km (ebike)
Hi, thanks for sharing your opinion with others. I'm glad that soaking the pads in mineral spirits, alcohol, or similar substances has worked for you. Unfortunately, it didn't work for us but maybe we were doing something wrong😉
You're welcome! 😊😊😊😊 I'm pleased that you found the video useful. If you have any more questions or need further help, don't hesitate to reach out. Happy cycling, and have a great day! 🚲😄
Hi Dakita and thanks for your question. There are many sizes and the best thing would be to speak to your local bike shop to find the correct replacement. I've attached a link to some of the sizes. wheelsmfg.com/products/hub-parts/all-cones.html I hope this helps
Hi, Yes, it might be possible. Sanding just makes the surface too rough and I don't know how to resurface. Not something that I've come across. When we write our videos, we do as much research as we can and draw on our own experiences. We then follow the route that will be the most successful. I would never doubt that there are many paths to true Enlightenment.
brand new brakes, properly torqued screws, thoroughly degreased with disk brake cleaner... squeeks like MAD BANSHEE at low speed... im guessing some form of misalignment.... they brake like hell also... like it is almos binary in that they are on or off... very little mid control... I know I could introduce air into the hydrolic lines to "cushion" the fel a little but I feel like that is so wrong from a mechanical standpoint. I feel like it is a harmonic issue related to manufacturing or misalignment... still not a big enough issue to make me buy anything new yet.

Maybe the quality of the shimano pads are not what they used to be😢Simply cannot get rid of that dreadful screech no matter what i do. The front brake is perfect!
Hi, and thanks for your comment. It can be really frustrating when those brakes just won't cooperate, especially if the front one is doing great! I'm not sure if this is because of the shimano pads. Try a completely new rotor and pads, bed them in and the brake should work as new again. Let e know if you mange to get rid of the noise and what did you do to solve it.
@@cyclemaintenanceacademynew pads on, clean rotor and no noise for a couple of days..then the screech/noise comes back😢Rubbed mud onto the rotor and again, the noise comes back after a while😅Maybe its because the rotor is smaller 160 and its takes more energy/power to brake..if you know what i mean.
We have hunting all year in Michigan I like mine squeaking... water from the grass/weeds make my brakes squeak, they can't get contaminated from oil I wax my chain, wash with only water. LOL
Haha, that's a great approach! It sounds like you're really on top of keeping things simple and clean with your bike maintenance. It's good to hear you’re keeping the chain waxed and not overcomplicating things with oils or cleaners. Keep riding safe out there in Michigan!🙂
Great video. I completely agree with replacement of pads and rotors, proper centering of the pads on the rotor, and some kind of bedding the pads. Below is a trick works well, and can buy some time, for example; if you just want to keep riding while you wait for the new parts to arrive, don't have the money for the new parts at the moment, etc.: Remove the wheel. Remove the rotor. Run the brake surface of the rotor against a bench grinder that has a wire wheel attached. Hold the rotor so that the brake surface is perpendicular to the wire wheel, vs. holding the rotor so that the wire wheel is "scrubbing" in line with how the pads run. This perpendicular smoothing by the wire wheel will take the sharp edges off of all the scratches on the rotor, so that the pads will stop "playing" on the scratches, like how a record player/turn table needle plays on a record album. Dress both sides of the rotor this way. A little flat sanding, as done in the video, on the pads, and quick wipe off, and then re-assembly the bike. The brakes will be quiet for a long time. I stumbled upon this accidentally when dealing with an extremely noisy and embarrassing front brake. Originally I tried cleaning, with no change. Then I used 60grit sand paper to sand both sides of the rotor, and the surface of the pads in a cross-hatch pattern. Still no change. Next, I replaced the pads with new metallic pads. Still no change. Knowing that the issue must be with the old rotor, I ordered a new one. In the mean time, I still wanted to ride, and thought, "I wonder what would happen if I just wire wheeled the rotor? It's clearly ruined/worn out, so I'm not going to hurt it." I didn't even remove the rotor from the wheel. I just held it up to the bench grinder, did my thing, re-installed the wheel, and went for a ride.........perfection! I recently did the same trick on another bike while waiting for the new parts, but this time, was more serious, and removed the rotor. Dressed both sides of the rotor, and again, with brand new pads, it was completely silent (I did replace the rotor a week later, once it had arrived in the mail).
Hey, thanks for your comment and sharing the advice🙏. It looks like you found a trick to give the od squaky rotors a second life. I loved that you tried because you had nothing to lose and it worked! I'm really pleased that it did the job for you and I hope others will read your advice and, if they have a bench grinder, they will try and share with us if it worked for them as well.

And thank you! I'm so glad you liked it. Squeaky rim brakes? You won't have long to wait...
Every time I replace the pads, I clean the brakes and pistons and make sure they are all moving equally. I also loosen the two bolts holding the brake to the bike or arch, squeeze the brake, and then retighten the bolts. It's fast and easy and seems to recenter the brake with the new pads.

Been throwing bikes out and getting a new one for decades when they squeaked. This is super helpful and cost saving!

Any help would be very much appreciated.
Hi Chris, thanks for your comment and I am so pleased that you found the video useful. Great to see your question and I hope I will be able to help. First I just want to explain to you a bit about the squeaky noise you hear. Whether this is a disc brake or rim brake, each time the pads hit the rim or the rotor they create vibrations. These vibrations make the air molecules vibrate around the brake and then travel. If the vibrations are strong enough they travel all the way to our ears. We receive them as a squeaky sound. Luckily most of the time these vibrations/sounds are not frequent enough to be picked up by us. So, what we need to do is to minimise vibrations generated by your brakes. If contamination is not a problem and the brakes make a noise when you are not using them then most likely your caliper is not centred and the rotor is hitting on one of the pads or even scraping on the inner surface of the caliper.
Try this:
- Have a look at your rotor and caliper. See if the gaps between each side of the rotor and pads are even and if the caliper sits straight with the rotor. If not then re-centre the caliper.
- spin the wheel and see if your rotor is bent. One piece rotors (made out of one piece of stainless steel) are more affected to bend while used. If yours is bent then you can straighten it at the point where it touches the pad. If you don't have a tool you can use an adjustable spanner.
If you think that it is bent too much or in too many places you may want to replace it. In this case consider buying a two piece rotor. They tend to be more bend resistant and disperse the heat better.
I hope this helps. If you still struggle or have any other questions feel free to get in touch with us.

Oh, thanks so much! I hope to fix my squeal tomorrow. I only have country roads with some steep hills to ride on. My brakes get used way too much!
Heavy ebike, it likes to run away. 🚲😳
Hey, you're most welcome. I'm glad that you found the video helpful. Let me know how you got on fixing your squeal. I hope you're successful.
Great video. One last thing to try is using antisqueal compound on rotor. It basically sands friction surfaces. Replacing rotors and pads for noise is for QUITTERS!
Love the “no quitting” spirit! Replacing rotors and pads is definitely the last resort for you persistent DIYers!🙂
Thanks so much! What was a mystery to me is now understandable. And I'll never forget to brake them in, again...
You're very welcome! I'm so glad the video helped clear things up for you. If you ever need more tips or run into other bike maintenance questions, feel free to reach out. 🙂
Thanks for posting video. I tried dawn dish soap with toothbrush scrub and that fixed my squeaky disc brake problem.
You're welcome.
I foolishly put oil everywhere including the pads, and it started making huge amount of noise. Thank for your video.
😂😂 same to me what did you do to stop
@@danrotich1293 I spent half a day cleaning the breaking pads on two bicycles. It eliminated 99% of the noise.
You're not alone, that mistake is more common than you'd think! Oil on brake pads can really mess with their performance, causing squealing and poor stopping power. It's great to hear the video helped you out! In the future, it's best to keep oil or grease away from the braking surfaces entirely. If the pads are contaminated, you will need to replace them. Glad you got it sorted!🙂
Love these vids. Mary is the Queen of all Manchester’s bike mechanics (and she doesn’t swear as much in these videos either!)
Thanks Andy. Swear "as much"? I think I've managed to totally avoid it! So pleased you're enjoying the vids. I hope they'll be useful when you're training people.
I've had problems with road disc bikes. Currently i have a hydrolic brake bike that screeches and vibrates alot under braking , this is after putting on new discs and pads ,not sure if i bed them in as you described. So I'll give it one last try.
My current bike is rim brake and is soooooo much less maintenance.
Hi, and thanks for sharing your experience. Sorry to hear about the issues you're experiencing with your disc brakes. It sounds frustrating, especially after installing new discs and pads. Properly bedding in the pads can definitely make a difference in brake performance, so it might be worth giving that a try. Let me know if you managed to resolve this and if you have any more questions or need further assistance, feel free to ask!🙂
@cyclemaintenanceacademy hi, I've now got a bike with brakes that finally work . Thanks for the tips .
It required new discs and pads and brake fluid , but the bedding in process helped with the re centering of the calipers.
Thanks again.
Was ready to bin the bike 😁😁
Iso alcohol wipe - fixed! Thank you heaps!
That's great to hear! I'm glad the iso alcohol wipe fixed the issue for you. Let me know if you need any more help!
Great video! One thing, I'd add is to avoid spraying lubricant or cleaning product around the rotor, as it causes that contamination you mentioned in the first place. Instead, spray your product on a fabric and apply it that way.
Hi, thanks for your positive feedback and for sharing your tip with others!🙂
Like I said absolute garbage and usless information 😂😂I use pur alcahol to clean rotors and pads and it sorts squeaking and rubbing 👍👍
Listening to commentary and effects mics on most of the Cobbled and Ardenne Classics and GTs most pros bikes squeal on hard braking and the commentators remark on it so I am not going to spend hours on all kinds of supposed hacks to get rid of it. Acceptance is the key !

Wow. First channel that doesn't just tell the same as everyone else. The obvious. They even disprove many of the common tips with argumentation as to why the tips will never work and in what situation.
I was so sure I had contaminated the set and have changed them three times now! It is quickly becoming a reason for me to stop using discs. But the glassing issue I have never heard of, so this is probably what is happening since I was sure oil was not an issue because I even changed the caliber once.

Hi Karen, let me know how you got on. Which tip solved your problem?
Thanks finally found the issue, only channel which addressed it until now.
Hi Stevko. Thanks for your comment🙏. I am pleased that you found our video helpful🙂
Very good video, disc brakes can be a real pain and on my road bike having tried everything you suggested I ended up having to change discs and pads before having to change the calipers as well. The cost is ridiculous for the limited improvement over rim brakes on the road. I will not buy another road bike with disc brakes again if I can avoid it. MTB is a different story, rim brakes are useless off road and for some reason disc brakes on MTBs seem to be more reliable 🤔
Hi Stuart, glad you found it useful🙏. Hopefully your brake is working like a dream now😉. I appreciate that you've shared your opinion with us about disc brakes on road bikes, it's an interesting topic. In February I am planning to start a weekly livestream to talk about bike related topics and this sounds like a great one to discuss👌. Hope you can find time to join us in the conversation😎.

@@cyclemaintenanceacademy thanks for your feedback Mary, subscribed and looking forward to your livestream
In my case, one or the other method works fine for the rear brake. However, I can't get rid off the noise for my front brake. I have done all mentioned in the video except changing the caliper itself, I don't see any oil leak though. I have been riding for more than a year with rear brake only to avoid noise at the front, which reduces efficient stopping. Only when I change the brake pads with new thick ones, the noise goes down, but after a little while they all start squeaking. Really annoying.
Finally I replaced the entire brake with a brand new one and the noise disappeared. It means there was an invisible leak of oil from the lever to the caliper. Such a relief.
Hi and thanks for sharing your experience. I'm glad you found a way to solve the problem.🙂
i havent performed, but am now ready to diagnose, etc. thanks
That's fantastic to hear! I'm glad the video has prepared you to tackle the diagnosis. If you run into any questions or need further assistance while working on it, feel free to ask. Happy diagnosing, and I hope you get that squeaky noise sorted out! 🚴♂️🔧
@@cyclemaintenanceacademy cleaned the rotors, and adjusted the cables, then did a few stops. It is now much better. Almost completely silenced.
thank you for enlightening me. I've been cleaning my brakes and it just won't stop squeaking. i just realized it has uneven bedding.
Thanks for your feedback. Let us know how the bedding in works for you.😁
i did the bedding-in braking only 17 times and it still worked!... impressive eh?
You are a true hero!😎 Guidelines are great because they keep everyone on the safe side - you and the manufacturers. Bike parts manufacturers like Shimano test their brakes (or, like food manufacturers, test their food to check if it's fresh up to the date they mention). Now, sure, your brakes will probably be fine even after just 10 tries, or those sausages might still be good a couple of days past the "best by" date. But that's where the manufacturer can't promise the brake pads will evenly transfer enough material onto the rotor or guarantee your stomach won't regret those sausages!😨 (By all means I've had sausages a few days past their "best by date," and surprisingly, they still tasted pretty good! 😂).
Hello, thank you for your video; what kind of sand paper grit should I use on my brake pads please?
Hi, and thanks for your question. I'm pleased that you liked the video.
To remove the glaze from the pads, all you need is fine-grit sandpaper. I recommend using 120 grit or lower for best results. Let me know if you have any more questions or need further advice.🙂
@@cyclemaintenanceacademy Thank you so much 😊
The alcohol method worked for me. Both worked on my old and new noisy brakes.

Very good explanation ! Thank you so much.
Thank you and you're welcome Monique 🙂
Thanks!! Simple and to the point.
Hi, thanks for the comment🙏. It's always good to hear that our video helped someone🙂
Disc brakes on a road bike are a nightmare - have tried all the above - MTB bike on the other hand works with no problem - didn't need to bed in, or any additional cleaning of the pad and rotors. Have now upgraded the road bike to Shimano dura-ace which has an increased clearance between pad and rotor - these seem to be working OK at the moment. Does leave the question as to whether the design of the road bike set up is flawed.
Hi, thanks for the comment and for sharing your experience with others. Sorry to hear that you had so much trouble with the disc brakes on your road bike. I hope that the new Dura-Ace brakes will finally put an end to your problem, allowing you to enjoy noise-free rides.🙂🚲
Hello, I have bought a NEW eBike and has now 50km. I realised that when braking harder, it makes the gurgling sound like bubbling! What is the problem and what should I do? Thanks for the advice in advance!
Hi, and thanks for your question. First of all, congratulations on your new e-bike. Regarding the problem with your brake, I would love to help but it's a bit tricky to offer the correct advice without seeing the bike. Can you take it to the shop that you bought it from? I hope you will sort this out soon. If you find out what the problem was feel free to share it with us. Good luck👍
I've got new pads coming in but will be keeping the rotor, hopefully my rotor is fine
🤞. Let us know if the new pads solved the problem.
Can i use 905 thinner instead of isopropyl alcohol for cleaning pads?
Hi, thank you for your question, and apologies for not being able to get back to you sooner.
While 905 thinner (a type of solvent typically used for cleaning and degreasing) can be used to clean certain surfaces, it's generally not the best option for cleaning bike brake pads, especially when compared to isopropyl alcohol.
Isopropyl alcohol is widely recommended because it's a safe, effective, and gentle cleaning agent that removes oils, dirt, and contaminants without damaging the material of brake pads. It evaporates quickly, leaving no residue, and is specifically safe for use on brake components.
905 thinner, on the other hand, is a stronger solvent and could potentially damage the brake pads or leave harmful residues that might affect braking performance. It is often used for tougher cleaning jobs (such as degreasing or cleaning metal parts) and might be too harsh for brake pads that need to maintain their grip and integrity.
If you’re looking to clean your pads, I’d strongly suggest sticking with isopropyl alcohol to avoid compromising the braking system's performance and safety.
You can also have brake noise from a sticky piston. Usually in this case the noise will be when you release the lever. The sticky piston does not retract fully and therefore your pads will be dragging on the rotor. The solution to this is to rebuild the caliper and make sure the pistons are not damaged. For less expensive brakes I think it's probably easier just to buy a new caliper.
Hey, thanks for clarifying this problem and explaining the solution! It's really helpful for other viewers to know about the sticky piston issue and how it can cause noise. Appreciate the insight!🙂
Great video and helpful, I’m not sure if my braking issue fits these issues. I just bought my Gravel bike back in July and probably have under 300 miles on it and my front disc brakes squeaks when I break. I can’t imagine the pads are worn or the rotor is bad. What do you think it could be?
Hi Joseph, thanks for your comment. Yes, it's a tricky one. What I can recommend first is to check if your caliper is aligned with the rotor. We made a video on how to do this, you can watch it here: ua-cam.com/video/J8OsyIOovbA/v-deo.html
Also, check if all the bolts on the rotor are tightened. Did you bed in the pads? If not then it would be a good time to do this.
If you tried all of these and your brakes are still squeaking then it will be good to try and replace the pads and rotor to eliminate the contamination issue.
I hope this helps. Let us know how you got on.
so on my new bike one of the brakes started Squeaking and it sounds uneven cleaned it and nothing and the disc is strait and the other things seem fine to so going to have it serviced
hi, sorry to hear about the squeaking brake on your new bike! It can be frustrating when issues like that arise, especially with new equipment. Having it serviced is a great idea, as a professional can help identify the problem and ensure everything is working properly. i hope they've managed to sort it out for you!

What type of sand paper should I get? any specifications?
Hi, and thanks for your question. It's a tricky one. You will find a variety of answers online and it really depends on your preferences. I use middle grit sandpaper myself.
Thank you! For me Magura rotors with Shimano resin pad made wonders.
Hi Lucian, thanks for your comment and I'm pleased that you enjoyed our video. Glad to hear that the combination of these components work for you. Did you try any other mixture of differnt brand rotors and pads to compare?
@@cyclemaintenanceacademy Thank you for your fast response.
I am Glovo cyclist courier. Pedaling around 20.000kms per year in traffic.
@@cyclemaintenanceacademy Yes, on my gravel/trekking bike I did pair RD 7120 SLX rear derailleur with 11 46 xt cassette 11, R8000 dual chain ring crankset and 11 speed XT shifter. I would have got RD8120 but couldn't find it at the right price.
I did this because there are no 11 speed rear derailleurs that work with dual chainring crankset and 11 46 cassette, only 11 42. Limited by design... But 7120 or 8120 12 speed derailleurs work with 11 speed systems in this scenario.

Soak pads in Fairy Liquid and rinse in Hot water & repeat
fairy liquid is a very good degreaser. Leaving pads greasy and squeaky free. Works 100%
Hi, thanks for sharing your experience and I'm glad this method worked for you. However using a wash up liquid on disc brake poads is niot recommended. While it may seem like a quick and easy cleaning solution, it can leave residues that may negatively affect the performance of the brakes. Dish soap is formulated to break down grease and oils, but it can also leave a slippery film, which could lead to poor braking performance, reduced friction, and even noise when the brakes are applied.
For cleaning disc brake pads, it's better to use isopropyl alcohol or specific brake cleaner products designed for this purpose. These cleaners are formulated to evaporate quickly and leave no residue, which ensures that your braking surfaces are free of contaminants and function as intended.
is it advisable to sand down rotor disc? i have seen some videos here on youtube where they sand the rotor but did not try it because i might regret it later..
Hi Jonathan, thanks for your question.
It's a tricky one and yes the vast amount of videos can be confusing and you're given conflicting information. Firstly let's see why some videos advise to sand down rotors (as this is usually not explained). So, the rotor does not get contaminated like pads. Sanding pads can potentially remove a layer of contamination (if you're quick enough). Rotors have a layer of pad transferred during the bedding in procedure. If that procedure is not done properly then an uneven layer of pad is transferred and this can cause vibration, which we hear as a squeaky noise. Only then sanding the rotors can potentially make a difference. It's hard to say whether this is causing the problem as the layer transferred is microscopical and not visible to a human eye. We do not sand rotors for our customers, for the price of a new one we just fit a replacement. However I understand that you may want to try it if no other solution works. First make sure that your rotor is spotless. Especially the edges of the holes on the rotor can collect contaminated dirt that can be transferred back onto newly fitted pads. I leave the decision to you.
Let me know your thoughts and if you decide to go ahead and sand them, share your results with me and other viewers🙂
Good ideas and solutions.
Thanks for the kind words!🙂 If you ever need more bike-related tips or have any other questions, feel free to reach out. Happy cycling! 🚲😊
If I let the pads with a little oil on them overnight and act tomorrow will it work?
Sorry for the delayed response! I would advise that if the oil has been left on the pads for too long, it can definitely affect their performance and cause contamination, making them less effective. Ideally, oil should be cleaned off immediately to avoid damaging the pads. However, since it's been a while since your comment, I'd love to know if you've been able to fix the issue! Let me know how it turned out.
Thank you. This is very helpful 😇
Thanks John, I hope it helped to solve your squeaky brakes problem
thank you so much so helpful and well explained👌
That's great to hear and hope you hear no more squeaking 🤣
Does this problem also come when we completely buy a new bike?
Hi, and thanks for your questions. Yes, that's possible as well. First try to bed in your brake pads. That's the most common reason why the brakes make squealy noise on a new bike. Let me know how you got on and if the squaky noise is gone.
how to choose a disk ? can i buy a cheep disk from aliexpres? are all disk the same?

1:07 => That´s EXACTLY my noise problem, that I have for years now !!! SM RT86 rotors with Saint M820 brakes. I tried the following organic pads: DS03S, Kool stop, BBB, Cube. The Kool stop were silent when they were new, but loud in the end, too. All other pads were loud all the time (especially in humid conditions). I love my bikes and I maintain them neurotically. I only have that problem on my Haibike FS RC 26 pedelec. Not on my recumbents or my E-Scooter. Does anyone have advice for me (speaking from experience with my above mentioned setup) ?
Hi, and thanks for your comment. I understand your frustration but don't throw in the towel just yet! Replace both the brake pads and the rotor with new ones, and bed in the pads. This will most likely do the trick. I hope this helps and let me know how you got on?
@@cyclemaintenanceacademy I cleaned the discs (also the cut out holes !) and the pads (on the inside) with acohol, filed the pads a bit down on the inside with a key file and then broke in the pads (20-30 times braking from 25km/h down to 15 km/h). The noise was gone after that :) It seems, that since I have more than one bicycle, I tend to neglect some things here and there ;_)
I have a continuous humming sound that only stops when I apply the brakes. Any ideas??
Hi Steve. Thanks for your question. The caliper may not be set up correctly. It sounds like your rotor continuously rub on one of the pads and it stops when the pads are compressed. Try to adjust the caliper so that the rotor sits evenly between the pads. We have a video on our channel on how to adjust disc brake pads. Let me know if this was of any help.
Well done. Thank You and good luck with your channel!
Thanks George, Glad it was useful:)
What is the likely cause if they only squeal when wet?
Hi, and thanks for your question. Because there is a very small amount of lubricant in water brakes can sometimes squeak in the rain. This should stop when they dry out. I hope this helps.🙂
Thank you for educating us :))
You're welcome 🙂
Can i know what's the breaking pads name please? Thanks
Hi, and thanks for your question. I imagine you are looking for a type of disc brake pads that will fit on your brake. The best way is to check the brand and model number of the brake and type this into googe (for example: Shimano Deore BR-M6100). If you have Shimano brakes and are not sure where to find a unique model number you can check my video here for guidance: ua-cam.com/video/9Mqx8qwKiHk/v-deo.html

I have changed my break pads but my bike still squeaks wot should i do
Hi Jack, thanks for reaching out with your question.
It might be that the rotor has not been cleaned thoroughly (which we all know is tough to clean because you have to reach between all these little holes). Even if you put in new pads, the oily residue from the rotor can still be transferred to the surface of the new pads and contaminate them.
Another possibility is that if the pads haven't been properly bedded in, an uneven layer from the pads could have transferred onto the rotor's surface, causing vibrations and that squeaky sound you're hearing.
You can try either thoroughly cleaning the rotor before fitting new pads or fitting both a new rotor and new pads and properly bedding them in. This should help eliminate any contamination or unevenness and hopefully solve the squeaking issue. Give it a try and let me know how it goes. Good luck!
Thanks do much my brakes are so stringa now
You're very welcome! I'm so glad to hear your brakes are working great now. Thanks for the feedback! If you run into any other issues, feel free to ask. 😊
I changed pads, did not work. I spray diluted dishwasher on rotors and squeaking goes away for next few hours ride. Don't know why.
Hey Niraj, thanks for your comment and for sharing your experience with others. Great that this method worked for you for a few hours however wash-up liquid is made of detergents that can be absorbed by disc brake pads. This will contaminate them causing squeaking and reducing braking power. I hope this helps🙂
my brother put break cleaner on his discs if it fixable?
Hey, thansk for your question. It depends. If the liquid he used had contaminate the pads then you may need new pads and clean or replace disc rotor.

What exactly is occurring with a glazed brake pad?
Hi. The material in the brake pad hardens and goes glassy.
Great video, though I think you can sand/resurface and clean the rotors instead of replacing them.
Hi, Yes, it might be possible. Sanding just makes the surface too rough and I don't know how to resurface. Not something that I've come across. When we write our videos, we do as much research as we can and draw on our own experiences. We then follow the route that will be the most successful. I would never doubt that there are many paths to true Enlightenment.
@@cyclemaintenanceacademy Ah, one can sand with increasing grits, or there's resurfacing paste available as well.
Recommended grit?
Hi, thanks for your question and I'm sorry for not abnswering it sooner. I would advise using a fine grit sand paper.
brand new brakes, properly torqued screws, thoroughly degreased with disk brake cleaner... squeeks like MAD BANSHEE at low speed...
im guessing some form of misalignment.... they brake like hell also... like it is almos binary in that they are on or off... very little mid control...
I know I could introduce air into the hydrolic lines to "cushion" the fel a little but I feel like that is so wrong from a mechanical standpoint.
I feel like it is a harmonic issue related to manufacturing or misalignment... still not a big enough issue to make me buy anything new yet.

Maybe the quality of the shimano pads are not what they used to be😢Simply cannot get rid of that dreadful screech no matter what i do. The front brake is perfect!
Hi, and thanks for your comment. It can be really frustrating when those brakes just won't cooperate, especially if the front one is doing great! I'm not sure if this is because of the shimano pads.

@@cyclemaintenanceacademynew pads on, clean rotor and no noise for a couple of days..then the screech/noise comes back😢Rubbed mud onto the rotor and again, the noise comes back after a while😅Maybe its because the rotor is smaller 160 and its takes more energy/power to brake..if you know what i mean.
Bedding the brakes in one at a time sounds like a good idea.

Haha, that's a great approach! It sounds like you're really on top of keeping things simple and clean with your bike maintenance. It's good to hear you’re keeping the chain waxed and not overcomplicating things with oils or cleaners. Keep riding safe out there in Michigan!🙂
Great video. I completely agree with replacement of pads and rotors, proper centering of the pads on the rotor, and some kind of bedding the pads. Below is a trick works well, and can buy some time, for example; if you just want to keep riding while you wait for the new parts to arrive, don't have the money for the new parts at the moment, etc.:
Remove the wheel. Remove the rotor. Run the brake surface of the rotor against a bench grinder that has a wire wheel attached. Hold the rotor so that the brake surface is perpendicular to the wire wheel, vs. holding the rotor so that the wire wheel is "scrubbing" in line with how the pads run. This perpendicular smoothing by the wire wheel will take the sharp edges off of all the scratches on the rotor, so that the pads will stop "playing" on the scratches, like how a record player/turn table needle plays on a record album. Dress both sides of the rotor this way. A little flat sanding, as done in the video, on the pads, and quick wipe off, and then re-assembly the bike. The brakes will be quiet for a long time. I stumbled upon this accidentally when dealing with an extremely noisy and embarrassing front brake. Originally I tried cleaning, with no change. Then I used 60grit sand paper to sand both sides of the rotor, and the surface of the pads in a cross-hatch pattern. Still no change. Next, I replaced the pads with new metallic pads. Still no change. Knowing that the issue must be with the old rotor, I ordered a new one. In the mean time, I still wanted to ride, and thought, "I wonder what would happen if I just wire wheeled the rotor? It's clearly ruined/worn out, so I'm not going to hurt it." I didn't even remove the rotor from the wheel. I just held it up to the bench grinder, did my thing, re-installed the wheel, and went for a ride.........perfection! I recently did the same trick on another bike while waiting for the new parts, but this time, was more serious, and removed the rotor. Dressed both sides of the rotor, and again, with brand new pads, it was completely silent (I did replace the rotor a week later, once it had arrived in the mail).
Hey, thanks for your comment and sharing the advice🙏. It looks like you found a trick to give the od squaky rotors a second life. I loved that you tried because you had nothing to lose and it worked! I'm really pleased that it did the job for you and I hope others will read your advice and, if they have a bench grinder, they will try and share with us if it worked for them as well.
And I'm glad that you enjoyed our video😊
Thank you.
You're welcome Jeffrey 🙂
nice thankyou
You're wlecome. If you need more advice or you've stuck with anything else just give me a shout.
This video was enough to scare me away from disc brakes forever. I stay away from high maintenance things & people.
Hi Matt, thanks for your comment. We had the same feeling when making the video😂
Living in a hilly district such as the Yorkshire Dales, and on a weighty Ebike, disc brakes are pretty much essential.......
Try hydraulic brakes. For me disc break is the in between of V brakes and hydraulic breals
Just clean them once in a while, who saying clean them every day😂😂
Love this comment
I have the same problem right now and I will let you know if this works.
Like the comment so that I can share the results.
Sounds great! Definitely let us know how it goes-I’m curious to hear if it works for you. I’ve liked your comment to make it easier to find your update. Good luck! 👍😊
Great, thanks
Glad you like it Ian :)
i think mine could be salt contamination salt in the air at my marina
Hi, thanks for the comment. That's interesting, I know that salt can cause corrosion but I'm not aware that it can contaminate pads and rotor. Keep us informed if you replace them and simmilar thing will keep happening.
