- About This Video
There are many benefits to disc brakes, but there are also many frustrations too. One of the biggest is when they start honking like a goose. Sorting this problem isn’t as hard as some would have you think, and in this video, I’ll show you how.
Screaming brakes is caused by one of two things, moisture or contamination. If your brakes are clean and dry, and they’re still screaming like a Banshee, then they’re probably contaminated.
Not only is the noise annoying to both you and everyone around you, but braking performance is reduced dramatically.

Finally, success. I had previously tried various aspects of the process, using isopropyl alcohol, plus cleaning the pistons with mineral oil, then drying. I strongly suspect that the rotor was my problem.
I went to the trouble of removing the rotor and using brake cleaner, for the first time. I also hit everything else with brake cleaner and also applied sandpaper and heat to the pads.
Before the rotors were even re-bedded, the squealing stopped.
Love this video. Some rotor cleaning vids border on black magic and incantations. There is no mystery. We cleaning metal using solvents to get all the grease off. The sandpaper cleans and smooths. Good old alcohol and acetone is all you need. Great stuff.
Glad you enjoyed it 👍
Even simpler: climb the highest mountain in your area and pull the brakes constantly while descending back down. By the time your back down the brakes should be hot enogh that every contaminant is either evaporated or has burned off. Repeat if necessary. This way you get plenty of exercise too. 🚲 😎
I've done this myself, gammelgemse. There is a fantastic climb in the Ribble Valley called Waddy Fell, it's ideal for this. I've also seen videos where people use blow torches..... Not sure I'd want to recommend that though!!
I like this method better. YMMV
Heat = warping
So no.

Dude you are a legend. My brakes have been a huge pain for me for months now. They start screeching, I clean/replace the parts, they start screeching, I clean them again.
I've done this over and over and over.
After reading your comment I lightly braked while pedaling (not even downhill) for 2 minutes. And voila, they were quiet again.
It funny that all the pro tour bikes squeal even with professional mechanics working on them daily.
Rim brakes with alloy rims are so much more enjoyable in the winter and carbon for the summer.
Disc brakes are for MTB’s.
My go to channel for bike maintenance......thank you
Kind of you. Thanks 👍
This howto helped my out to cure squealing Front break after upgrading my wheelset and installing Icetech XT rotors (MT-800). After doing battle with my issue for some time, It came down to a few key points. 1. use clean microfiber cloth to wipe rotors after using high alcohol isopropyl or (rubbing alcohol ) or rotor cleaner to get them as clean as possible. 2. clean the break calipers also with isopropyl well getting whatever grit in there out. 3. Ensure your calipers are straight as possible aligning with your rotor, assuming your rotor is also not bent. 4. Newer Icetech routers may be slightly thinker brand new. Its best to get new break pads that also match the rotor (new pads may be slightly thiner). My case: BR-M800 caliper to j05A resin pads. Previously metal J04. cleaning the previous pads might have also worked but also but just getting fresh pads seemed like the better option. The newer Shimano pads come in a paper box rather than the plastic. Also the back of the break pad is one solid black piece. Resin pads are more muted but no more squeal! I may go back to J04 metal later but so happy my bike is quite now.
Glad you enjoyed it. I too used to run sintered pads, but as I’m not an aggressive rider, the increased noise far outweighed the increased performance. I just stick with resin now. No noise, and my posh Hope rotors will thank me for it in the long run.
I'm taking delivery of my first bike with disc breaks this Saturday. Now I have a list of products to get and a "go-to" video as reference in case I need it. Great job.
On cars we put a small amount of copper grease on the back of the pads to dampen noise from vibration.
I do the same on my bike, for that exact reason. MTB’ers also do it. I personally won’t ever recommend it though, because if it gets on the braking surface, it’s new discs and pads!
Maravillosa explicación, muy didáctico el video
Thank you 👍
Just had to do this today Jon, mine were squealing like a banshee. Haven't tested 'em yet though. Keep your fingers crossed for me. Good video, thanks 👍🚴
Fingers crossed Pete 👍
@@ribblevalleycyclist No joy...tested this morning...still banshee like 🙄 Persevered, recleaned rotors and pads but this time used nail polish remover, re sanded then cleaned again using nail polish remover...as silent as a silent thing. The difference this time around...nail polish remover as opposed to iso propyl alcohol or even muc off specific cleaner 🚴👍
Great video, very helpful to a disc brake newbie. The links at the end didn't appear though.
Hi Work In Progress. Glad you found it useful. Thanks for the info, I'll go and check it.
I have been using Gorilla pads since 8/2021 (around 15,000 miles now) and my experience is as yours. 100% agree with you about price and the Shimano cooling fins being unecessary. I find they last much longer than the Shimano equivalents. The ones I use are for: Shimano Dura Ace BR-R9170 Ultegra BR-R8070 BR-RS805 BR-RS505 BR-RS405 BR-RS305 L02A - Enduro kevlar. Great videos - thanks.
Hi Kirk,
Glad you liked the video. The trouble is, a lot of people just think they have to use the one from the groupset manufacturer........ odd, because people don't do this with rim brakes.
I did a more detailed video on these pads, link below if you've not watched it already:

Thanks for watching,
Jon
🙄I intended to make my comment against your video about alternatives to Shimano pads - apologies! I'll post the comment again, against the correct video this time. @@ribblevalleycyclist
I'm not gonna complain about anyone binge-watching my videos @@kirkalderson4005 🤣
I purchased some Gorilla Finned semi-metallic brake pads on your recommendation. They universally fit 105, Ultegra and GRX, for only £11.99+ a pair. I'll try them out before replacing the rotors
Keep us posted, Justin 👍
Dear Ribble Cyclist, I saw Fenwicks All Weather lube in the video. Can you recommend it to me for the winter months? And does the chain still remain a little bit clean with this lube? Thanks for your help with all your video's. They really help me everytime !
Hi, Yes, it’s my go-to oil nowadays for the winter months. There are other options out there, from big brand cleaning product manufacturers for example, but your drivetrain ends up looking like you used crude oil!!!! The Fenwicks is a great product 👍
Merci!
Thanks, Denis 👍
Personally i would clean the pads then make sure there fully dry and sand them. And NOT clean them afterwards cause that brake dust will help to get them broken in faster.
I'm surprised you didn't mention 'upgrading' the pad retaining bolt with one with a hex fitting. I'd left mine too long and of course it sheared, then sheared from the other end (with a set of grips on it) and required drilling out which was is something I don't want to repeat.
In terms of brake cleaner, a mate (who also has a road rally car) uses Nappa brake cleaner in a standard pressure sprayer (the type you can buy for weedkiller) which seems a good compromise between ££££ bike products and the cannisters that last about 30 seconds before they're empty (the local place had a can of Weldtite Jet Blast and whilst effective, it didn't last long at all). I recently also invested in a tool to push the pistons back in which has been pretty handy of late although I'm kicking myself for not going for the PT.
Good shout, Paul. Agreed, a hex bolt is a nice upgrade. Saying that though, a blob of something on the thread and not installing it with a jack hammer is also affective 🤣🤣🤣.
Yeah, a lot of cyclists turn to car brands for disc cleaning products. That one I use is made by a car company! Pistol tool, I just use the handle on my long nosed pliers!!!!! Yeah, I know, I should use the correct tool. I have one somewhere, but I misplaced it about 6 months ago. I've not replaced it, because the current solution seems to do the job even better than the correct tool. Maybe I'll treat myself to a PT one soon.
@@ribblevalleycyclist it was the neglect that got me this time. The state of the pads was a touch embarrassing. It's safe to say that my wife's bike, my bike and my Dad's bike all of which seem to fall to me to keep on the road are now hex.
We've all been there!! I have a pal that had to buy a new calliper.
Cleaning the brakes fixes my problem for about 2 weeks. After that they're noisy and have terrible brake force again. I've done this a few times now.
Any idea why the problem comes back all the time?
Do we need to bed-in the brakes after this operation? Thanks!
Hi Denis. Yep, a good idea to bed them in again. Thanks.
@@ribblevalleycyclist Thank you for the reply! Always a pleasure to watch your videos. Be well!
@@denis_roy_7 Thank you Denis. And it’s always a pleasure to hear people getting something from them.
Great video, but off to the bike mechanic for me!
Hope you get it sorted 👍
Can you use acetone on rotors to clean?
Yes, no problem at all. I wouldn't use it as your regular go-to cleaner though. Brake specific cleaner has additional additives for removing brake film and grease, that you won't find in acetone.
@@ribblevalleycyclist What about 99% isopropyl alcohol?
@@yonglingng5640 Yes, same as previous answer, no problem at all. I wouldn't use it as your regular go-to cleaner though. Brake specific cleaner has additional additives for removing brake film and grease, that you won't find in isopropyl alcohol.
I really do not like disc brakes especially hydraulic ones. I’ve had two back wheel lockups both times came off, and a failure of the front brake on a steep downhill it’s a good job I used to race cyclocross 😵💫 if I had to use them I’d choose mechanical ones. They are fully adjustable great when you’re out on a ride and hear the dreaded PING PING 👍
I find clarks discs make noise too if wet no matter what try im getting Shimano ones
Sintered/Metallic pads can also be the cause of noise in the wet.
@@ribblevalleycyclist yer but if bed them in with shimano discs i never had problems. I try clarks on and off years always crap it just i made mtb and got clarks brake set so put on discs as all had in 6bolt . Roll on pay day for new discs lol
@@ribblevalleycyclist by way got resin pads at mo so must show discs no good there diff steel sure of it
Agreed, if you’re getting noise with resin, then there may be a disc issue
@@ribblevalleycyclist cheap steel maybe dont no . Prop get shimano xt discs . My bin will like clarks ones 😂👍
Nope, too much trouble! Rim brakes or let it squeal! Bring back the simplicity of bike riding!
Unless you have an ebike.
Has anyone noticed that when wet previously contaminated brakes are ok.
Sure, if that contaminat was water soluble.
Isopropyl Alcohol on all surfaces , pads and rotors.
Sounds like a good idea. If it works, go with it 👍
If you want a heavy noisy bike buy a disc brake one
Didn't a 5.8kg disc brake bike just win the British National Hill Climb Championships? 🤔
@@ribblevalleycyclistthe bike would have been lighter with rim brakes only an idiot would ride a disc brake bike on an hill climb
@@Tarmaccyclocross So Andrew Feather, the British Hill Climb Champion, is an idiot....... I think we're done here.
Don’t use acetone without gloves
