Someone else has probably already commented on this but as a bike mechanic I've done many many bleeds and a little tip is when doing a lever bleed it also helps to tilt the lever both up and down 45 degrees while pumping it as bubbles will sometimes hide along the edges of the master cylinder. PS...you guys rock!! Cheers!!
Great tip!
Dude an year later, different bike (Gravel) That solved an issue i tried to solve multiple times with an full bleed.
Cheers.
I wondered where those bubbles were coming from. Thanks!
The lever wasn’t full with oil. The mineral oil entered the lever replacing air with oil. The replaced air exits as bubbles.
I love it how you guys didn't edit out all the small mistakes. Typically maintenance videos are about perfect execution of steps but in reality, we all make mistakes. We also learn from our mistakes and we can learn from other people's mistakes too. I think one of the greatest fear of new comers is "What if I make a mistake". This video shows that it's ok if you make a mistake, just learn from it and get it right the next time. Great content!
100% agree
We'll be posting a video about how to do a full bleed later this week so make sure you're subscribed!
Nice! The shimano bleed video from the SC/Syndicate mechanic is awesome and solves the issue most brakes calipers have which is dirty/non moving pistons.
😍
¿Sabes que es lo que me gusta de ti?

Es eso, además del corazón de niña que tienes todavía, eres como una fuente cristalina...
I would like to subscribed but the lack of closed captioning sadly discouraged me from doing so.
I've never thought about doing lever bleed only. Always did full bleed, but this makes a lot of sense and it's so much quicker. Thank you, this was really useful :D
These guides are brilliant, especially the format of filming the whole process and then adding a quick step by step at the end - perfect when sat in the garage with the phone at hand.
I’m loving all these tutorials! I just got into mtb and these are definitely the easiest to follow along with as I try to fix up my own bike
Hey guys, just wanted to say that your new channel is soooo helpful. I love the format. This vid especially, as in the past I'd just thought, "Brake bleed? No way. Down to the bike shop I go, that sounds too technical". They're really confidence inspiring vids, so thank you!! And it's also super useful to hear stuff in layman's terms too rather than all the technical jargon that often makes a job sound way more complicated than it actually is. Keep up the good work yous two!
Excellent. I order a bleed kit a few months ago but was a little nervous to do it until I watched this and it went flawless.
These are great! Really appreciate and enjoy the new channel. It will be very helpful as my son and I will overhaul our two bikes over the winter. The Shed is great too! Love all the parts on the shelves!!
I have learn a lot from the two of you on bleeding my brakes I just started using hydraulic brakes. And I had no problem installing them thanks to the two of you here.
Fantastic! Thanks to you, I managed to do a lever bleed within minutes - and there were lots of bubbles coming up :) In the end, it still turned out that I needed to replace my pads, but now I feel confident enough to perform a full bleed if needed!
Alright. I'll finally give this a try. I've been waffling on whether or not to bleed my own brakes, but I'll start with a lever bleed. Thanks as always.
Hey guys, thank you so much for common sense, relatable, understandable instructional videos!
I think these are great tutorials! I also really like the idea of the more in-depth part along with a quick recap at the end!
Thank you for this! I used this guide to fix a brake lever that went squishy. I've never had hydraulic brakes before and they seemed like black magic, this video totally demystified them for me.
Thank you so much for this video! It immensely helped me. My rear brake was near totally useless and I couldn't get any time from a bike shop to look at it because of them being booked up for weeks in advance. I use my bike everyday so this was a total life saver, totally fixed my problem. Thanks again!
This was awesome, thanks. I've happily changed brakes and bled everything on my car and motorbike but pretty new to bicycling (as an adult anyway). Bike brakes are so much smaller and more integrated than on vehicles, I was a bit confused but I feel much happier understanding the fill / bleed point and how easy it is. Great video.
I'm not the first to say this but THANK YOU for this video!! I've had a kit in my garage for maybe 2 months now, but haven't had the courage to tackle the job for fear of messing up the whole brake system and being without my bike until the shop could fix it. As Syd said, this completely "demystified" the process and everything went smooth as silk. Got out tons of bubbles on both brakes, but no dark stuff... woohoo! Thank you thank you thank you. Can't wait for the full bleed vid!
Great video. Just did a lever bleed and was so simple with your help.
Great demo. Gonna try it now!
Great tip, I was about to do a full bleed and this helped me a avoid that longer process. Thanks
Another helpful maintenance video. Good job. Thanks for doing this.
Much easier than I was expecting it to be. Thanks for sharing.
Thanks team. Your instructions worked like a charm!
Thank you for saving me time trouble and money. I really like to know my bikes in and out and do as much as possible.....watching these tips helps me do it right the first time
I love the format of these videos. It's super helpful to someone who is trying to learn more advanced bike maintenance. Thanks guys!
Loving these videos!
Well done Syd... I can see you getting more confident in every episode!
Just used this to do a lever bleed. Bloody awesome. Braking power is much improved.
Infinitely useful video, thanks team!
Did my first lever bleed today !! Thanks for this !
really well demonstrated and explained thank you both.
Great channel, could be the best channel I have found for helping us learn how to work on our bikes. Thanks!
Thank you for this video. Got a new bike and after a few weeks the rear break started getting soft and pulled to the grip. After watching this video I ordered a break bleed kit off Amazon and used this method to bleed it and it worked perfectly. Thank for sharing.
You pair totally rock! I have followed loads of your tips and this brake lever bleed was just the best ever! Now i can stop again :) Thanks very much indeed.
Again Syd you are awesome!
Did this with my new SLX brakes with fluid already in them. Cut the hoses down and followed this guide. Done in 10. Thanks you two! 👍
I SOOO needed to see this!
Excellent video. I need to do this today. Thank you!
I barely ever comment on youtube vids but this one has been so helpful that I feel I have to. I just followed this video to do a lever bleed on newly installed Shimano GRX STI brake/shifters (road-type hydraulic brakes) after shortening the lines and it worked as brilliantly as on mtb brakes. The only difference is that for road brakes you need a little adapter thingy to screw the bleeding funnel into place.
Thanks for all your vids - insightful, concise, entertaining and very well made.
This one and the one on how to set up tubeless tires with a floor pump are my current favorites. They both meant breakthroughs in my bike-building project!
greetings from Belgium!
So good. My 12 year old son, also my bike buddy and budding mechanic, is eating this up as well. You've got a great thing going. Thanks so much.
Unsurprisingly incoherent.
@@strategicthinker8899 ?
Very helpful for me I had no idea how to sort my XTR spongy brakes - you explain it well for a novice like me. Subscribed !
Another great video, thanks! I am saving this one to my Favorites for future reference.
Worked perfectly, thanks
My front brake went from a working state to not at all between rides. I wasn't sure that this would fix my issue but after a test ride, this seems to have resolved the issue. Thank you! Subbed!
Same heare, went from having to pump them to not touching the rotor in 2 days, tought for sure that my levers and/or calipers were dead, I followed this video and they feel brand new again. Thank you Syd.
Thank you for these videos!!❤️ I feel like with your videos I do get a real understanding of the maintenance procedures. With oder tutorials I feel like I watch someone do maintenance without me learning anything.
PS: I‘m sorry if my grammar is a litttle bit off. I‘m from germany and my english isn‘t the best 😬
Thanks for this video saw it when it was new, but just did the process today very helpful and entertaining
Great, easy to follow video. Thanks!
This is so helpful! Thanks 😊
super helpful! thank you
Awesome vid. Thanks! One of my Shimano levers is squishy, so I'm taking this video out to my work bench.
Worked like a charm!
Great video…
Worked perfectly for me.
Thanks!!!
I bought my first bike with hydraulic brakes and this was very helpful... Burping the levers. It's just like burping and bleeding my ranger's hydraulic clutch line... Thanks guys... Keep up the good work...
I enjoy watching your video A true bike mechanic 👩🔧
I'm gonna attempt to do this for the first time this weekend. Great vid!
Found this channel this week! Keep it up and enjoy the tons of information and great videos. Have a 22 Marin rift zone and can't wait to get some wrench time!
Great video. Simple and to the point! You just got another subscriber.
Hey Syd and Mackie. I have tried multiple times to make my hydraulic brakes to work, not succeeded yet, but your video is so upbeat and straightforward I am going to try again. I especially like the video format of going slowly and then repeating the steps in summary. Great job. I will support you with $
Well done and I just ordered the shimano cup as I had Avid brakes before, that is so simple :)
You did the great job, I try my first bleeding in next few days, thanks
Thanks! Very useful video!
Danka 👍 good timing as usual 😁
Here is a tip that helped me. When you pour the mineral oil, turn it so the jug is sideways. This way it will pour easier without the “gulps”. Its like pouring windshield washer fluid into a car. Thanks for the great content on this channel!
Yep, same with pouring a quart of oil into your engine.
Fantastic video. Thank you.
This looks like something even I could do! Thanks! 😄
Thank you Syd! Appreciate you.
thanks for the great informative video !!
Triple thumbs up! I find it helpful that you leave the missteps in the video.
Tip! If you're just doing a lever bleed, maybe best to pull pads and put a bleed block in so you don't overbleed the system. The last lever bleed I did was with worn pads & wheel in, meaning the pistons were already extended a bit. When I later replaced the pads & needed to push the pistons back in, it actually over-pressurized the system & I had fluid blow out the relief valve of the lever (as it had nowhere else to go). In hindsight, an alternative solution to this would be connecting the funnel before pushing the pistons back in, giving the excess fluid a place to go.
If you put a bleed block in then you are fully compressing the pistons making the total volume smaller, then once you put the wheel back in and the pistons readjust to the much thinner rotor you are increasing the volume and will be back to the same problem of not enough oil to fill the volume. You actually solved your own issue in the second part of your statement though. When you change to brand new pads, screw in the cup with oil, remove the old pads, compress the pistons, install the new pads, install your wheel, then finish the lever bleed.
@@Sandriell The brakes and reservoir volume are designed to be filled with the bleed blocks in place and can accommodate worn pads. If you overfill the brakes, on the other hand, you might not be able to change brake pads on the trail! That might not be a problem on a short ride, but if you spend a day in the mountains it is a no-go.
Completely agree with this - this video basically shows how to overfill the system, which is why the lever feel better afterwards. The air coming out is a result of the pistons advancing and the additional space being taken up by fluid in the master cylinder. IME if you're getting to the point of the lever being back at the bars then either the pistons are sticky and not advancing correctly, or you have wear on your pads or rotor.
@@leepowelldev that's the whole point. To bleed the brakes to account for the wear of the pads and rotors
Yup you did the right thing. It's like on a car when you top up the brake fluid when the brake pads and rotor wears down, creating more travel in the system. But when you push the calipers back you take fluid out of the system so it doesn't over flow.
thank you this was too easy 🙌
great video! You deserve way more subscribers
Just what I need to do. Waiting for my cup and oil to arrive. Thank you.
Great stuff Syd and Macky on the Camera 🎥👍🚴🏴🏴👌
Love your videos
Just done this on our Cube MTBs.
Thx for the video 👍👍🚴🚴 UK
This is the most inteligent and easy explain video about brakes i ever seen. Keep going, im interested. I do some services too, but if i do something once per year, i looking on internet for being sure i know what im doin. Cant wait for some realy big services videos. Thank you and i wish you succes.
Looks like Gaerne SG10's on the shelf(MX boots). Those were my favorite back in my riding days. New to this Mountain Bike stuff and your channel has answered all my questions!!! Thanks!!!
Thank you so much for your lever bleed video. I own a Sur Ron X. It has 4 piston calipers(unknown brand) without bleed nipples. And with all the videos referring to Sur Rons, there are none explaining bleeding the brakes. This video helped. Thank you.
Love ya Sid, flat works for me.
Yes, everyone with Shimano brakes should have a funnel and mineral oil. It’s crazy cheap and compact and the lever bleed process is a cake walk.
Really good!
Great vids keep up good job guys
Thank you kindly
Followed this video today and did it myself. Thanks!
Congrats!
@@sydfixesbikes I even used a yellow paint pen like you did
Thank you
Thanks!
thanks guys this is just what I needed to find out. Time to get bleeding! :D
My new to me bike has some Hayes Prime Pro hydraulic brakes...and the front went real squishy today....gonna try doing this...thanks! I subscribed! I'M just one guy with a bunch of broken bikes with very minimal time to ride....but definitely want to....thanks again!
😇🙏💪
thank you!
This worked a treat. Especially helpful were the deliberate mistakes. I would almost certainly have lost the o ring!
Thank you soo much
Bought a new bike online, great bike but the company shipped it with zip strips that caused multiple knicks in rear brake line.
Im a rook so I had a local shop repair, dude got lazy or hurried or wtv and brake was still very spungy.
Watched your vid and resolved issue in 10 min!! Thank you!!
wow, watching you for a last week, guys you are runing super duper interesting youtube channel!
Thank you for a great video which guided me flawlessly as in get it right the first time fixing my rear brake fluid problem. Comprehensive!
thanks!
Love from Norway.
Just did a lever bleed on my wife's bike. Front brake was squishy. I followed your instructions and got a lot of air out of it. Lever feels great now. Also followed your burn-in instruction video for a new rotor on the front after a crash. Also a success. Thanks for the help!
Love these videos!! Sid your eyes crack me up. You look so stressed!!! But you know it all !!
