- Usually centering you bicycle hydraulic disc brakes takes care of pads dragging on the rotors. If it doesn't, there are typically two other issues to look at, which I show in this video.

For 3 years, I have endured rubbing front disc brake. Lots of useless advise led me to change: pads; rotor; mineral oil and bleed; calliper. My local bike shop couldn't resolve (in fact made it worse!). I even bought new wheels (not because of rubbing) which had the exact same problem. 3 minutes of watching your video, and I thought 'heck, let's try this'. 15 minutes later, problem was resolved! Thank you so much for such a clear, simple solution!
Brilliant! Going nuts trying to fix my dragging brake pads. Tried to exercise the pistons again and again to no avail. Removing excess fluid solved the problem immediately. In hindsight, the brake lever was very tight and a sign that the fluid had expanded. I don't know why other videos aren't showing this, but thanks a bunch.
This is the literally one and only video dealing with this issue. Very helpful and saved my weekend!
Great video. So many videos out there that basically teach you to center your brakes. this one helped me diagnose and fix a rubbing pad that was driving me crazy. thank you!!!!
Great, video! It is amazing how many cycling channels do not cover this. They generally just talk about a bent disk or centering the caliper. again great video, very informative and simple to follow.
Is the rain water dirt affect the disc break working
Amazing! This video stopped me from having to go to my local bike shop pleading for help. Thank you so much for making this video short and sweet!
4 years later and this video finally ended hours of frustration trying to get my caliper centered. Apparently my grx brakes were over pressurized despite following the shimano manual to the T. Thank you!
Was a little intimidated working on hydraulic brakes for the first time, your video was to the point and very informative. Thanks! All working well now.
Thank you so much Clint. After trying out about 20 other videos all of which suggested the same solutions of straightening the caliper, truing the rotors etc etc, yours was the first and only one that suggested relieving a few drops of mineral oil from the system. This solution immediately solved the problem on my Canyon CFR running Campag Super Record EPS and it was quick and easy for me to do. Quality content from knowledgeable people like yourself is hard to find out there in a sea of repetition and ineffective solutions purveyed by so many others. I’ve sent a super thanks your way. Thank you 🙏
Love it. So glad I could help!
As usual..concise and accurate information delivered thoroughly. Many thanks Clint. Greetings from The West of Ireland.
Top bloke. Just solved my irritating disk rub issue after viewing this vid.
Huge thanks. I was trying to resolve brake squeal but after cleaning and scuffing the pads 3 times, I found the pistons were not moving equally. One was almost stuck. I guess the imbalance of piston pressure to the pads and rotor was causing the squealing. Followed your instructions and the piston eventually worked together in equal movement. Took it out for a test and voila. They no longer squeal.
The video addressed the issue I was having with a new bike build, which was excessive hydraulic fluid in my front brake line. Thank you Clint for your clear explanation!
if you drain the fluid, does it not make the brakes more mushy?
Thank you very much for the tip about too much pressure in the system. Had very little clearance on some new pads and was finding it very hard to get the calipers centred well enough to stop all rub. Just did as you said and bled off a little fluid and all is right with the world again.
Relatively new Tarmac… tried everything… and the solution was your last step. Bleeding them a bit gave me enough gap to finally end the rubbing. Thanks!
Thank you for posting this, clear and simple to follow and solved my brake problems.
Thanks a lot for the excellent explanation and demonstration! I’ve got excessive pressure in my system , but I was afraid to open a bleeding port because I thought the whole bleeding process will then be required and I do not have tools or a good service shop where I live… so I fixed my brakes in a few seconds after watching this video 🤌 thanks!
Many thanks Clint for your excellent tutorial. I just loosened the bleed port screw and out flowed the brake fluid.
I now enjoy no brake pad drag.
Brilliant video, right to the point ! Very well explained and shown !
Thank you so much, excess pressure was the problem for me, fixed thanks to you :)
Thank you for the video. It seems like something always needs to be tweaked on my MTB bikes. Always learning....
Thanks! Went from cool and dry, to warm and humid. Pads were DRAGGING this morning. Quick watch of this video and 20 mins later I was ready to roll! Thanks again! (note, wish i could have tipped more, but no option beyond $2)
Thank you
Finally fixed after trying the last step of soaking up a small amount expanded of fluid. No more rubbing after centering, lubing the pistons, repeat, and repeat. Thanks!!
Great Info....Perfect timing for gravel ride tomorrow.
Thank you, thank you, THANK YOU!! I wish I would have watched this an hour earlier than I did.
As usual your video is so informative you have save me a lot of mullah n frustration n time, more power to your show n stay healthy n safe alwayz
Great explaining about both scenarios. Very helpful. Tks
Great one. I've seen tons of videos on how to do the first part but none of all this. Awesome
Unbelievably helpful. Thank you.
Very helpful. I have new Shimano XTs and rotors and they were dragging. I went thru you list of remedies and found loosening the mounts to center the rotor was the answer. I just flipped over the bike and spun the wheels to feel for vibration between the rotor and pads as I incrementally tightened the mounts., I had to do it by feel since they are so close I couldn't see the gap and clenching the brake levers down and retightening the mounts wasn't fixing it.
The Birzman Clam was a very useful nugget. Thank you Clint.
I was searching the comments for the spelling of this little tool. Thank you
Thank you! I tried everything to push disks between new pads after replacement. Was ready to mess with bleeding screws... So, you saved my sram breaks! :)
saved me a trip to the bikeshop! thanks!
Fantastic, finally s.o. to cover this!
Excellent video. Thanks for posting.
thanks a lot! it fixed my problem, super helpful .
Thanks for this Clint. Great info.
Very helpful. Thanks for sharing.
Great video! One thing I would recommend is checking the rotor to make sure it is warped / bent. Just look straight down at it between the pads while spinning.
This technique worked perfectly. Saved me!
Good vid thank you. I had to go thru this procedure after a buddy of mine decided to squeeze my left lever with the bike on the repair stand and the wheel removed....took a while to push the pistons back but the plastic levers did the biz.
Got it. Very informative!👍👍👍. Immediately subscribed.
It was a very helpful video. Thank you sir!
Gonna hit this again. Noticed you mentioned pushing them about 6x..haven't heard that before but have endless rubby and also squashy underpowered brakes (deore xt). Also been through the mill trying all options, convinced it was a stuck pad issue but only cycled them once or twice. ...I'll be back shortly (as big Clive would say)😄
That was extremely helpful.
Thanks a lot.
Very helpful... I learn more stuff about the bike... thanks!
Thank you, Clint Gibbs!
Thank you, this is great information
You are a life saver sir Clint 💪🤘🙏
Exactly my problem - now I have the solution. Thanks a lot.
thanks for that great explanation... greetings from Brazil.
This helped! Thanks.
You’re the man! This solved my issue.
Great video. Thanks
The tip about expansion of fluid was the ticket! Thanks!!
👍
Thank you for your advice. 👏👏👍Saves me from madness.
Tyre lever did the trick!
Very good information video
thanks you saved me lots of time and agony with this video!
this really helped! thanks!
Great explanation and the tyre levers work a treat! I’ve just done it successfully in my Sram Code RSC. I previously popped out a piston in Sram Guide so your tip not to push the piston out more than 3 mm has saved me this time. Cheers 🤙🏽
Had brake drag and was working on it for hours before your instruction. Thanks for making my ride drag free!
i was replacing brake pads on sram apex 1 equipped bike, the pistons woudnt go all the way back, this fixed the problem :) thanks!
Excellent advice!🇬🇧☺
Thanks for the great video. I wish I could go out to the garage in T shirt and sandals and work on the bike...not happening here in Northwest Indiana.
Great video, thank you.
Awesome video! worked for me
Hoolee cow. He's talking about bicycles! I listened intently the first 50 seconds.
Brake bleed was the culprit. Thank you!
SUCH A GOOD VIDEO. THANK YOU. Sorry stuck on caps
Spot on thanks
Thank you!!!
THANK YOU!!!
Thanks Clint 👍🚒🇬🇧
Brother, Thanks!!!
I might have a rear dragging on my hardtail 29er I need to scope out. Good timing
ElevationEveryWeekend check the disc too could be slightly warped and rubbing in a certain place win the wheel spins
Thanks
Thank you ,my problem solve.
That was very helpful
you prolly dont care at all but does any of you know of a tool to log back into an instagram account?
I was dumb lost my password. I love any assistance you can offer me
@Sterling Ayden Instablaster ;)
@Jacoby Alfredo thanks so much for your reply. I found the site thru google and I'm trying it out now.
Seems to take a while so I will get back to you later with my results.
@Jacoby Alfredo It worked and I now got access to my account again. I am so happy!
Thanks so much, you really help me out !
@Sterling Ayden no problem =)
My mtb has been sitting from just this issue. Went to put new pads on, and the new pads would rub the rotor. Not sure what I did, but when I let a little fluid out and I lost pressure in my brake lever. LBS will save the day!
DOT is awful for Florida, I really like the feel of SRAM brakes, but I won't run them because of of the extra hassle.
Thanks!
Thank YOU!
Thanks for this vid! Brand new Codes on my bike and the front brake was dragging ever so slightly. Took the pads out and pressed the pistons back in and voila! Problem solved!
Thank you SO much for this video, Clint. You are a cycling demi-God. Had a stuck piston and tried all the suggestions in other videos and nothing worked until i back-bled the system. Piston popped right back in. Question: I've obviously got water in the brake system now. Is that an indication to bleed the affected brake?
If you have not bled the brakes in every year then I would do a bleed. However, if you just don't have the tools to do it, you could wait and see if you have that problem again.
Cool and useful video. I am curious about this little pad centering tool you show at the end. Can you provide a reference on it - brand, store, etc. Sounds useful to have.
Check out one of the links in the description below the video. It's the Birzman tool
I have the tool myself, it is good quality but...it's squared at the top edge, so if your using narrow rotors (SRAM for example use narrower than Shimano) it's not going to be sitting flush on the ring. I love the look of the tool but they should have rounded the top instead of square folding it. I tend to use a thick sheet of paper each side instead just for accuracy (paper is pretty accurate lol)
Is it necessary to remove the brake pads? Seems like you can push in the pistons while the pads on still on. I have 2-piston Shimano XT brakes. And thank you for this.
Thank you for this great tutorial. I'm confused about you mentioned Di2 specific fluid. Doesn't the regular Shimano mineral oil works for Ultegra BR-R8070's?
All Shimano brakes use the same Shimano mineral oil
Is it possible to remove brake fluid?
if the piston is stuck, could it be from dirt? If so, i would assume you should clean the piston before pushing it back in.
Great video. Thank you. Are you using tyre levers because you do not have the dedicated tool to spread the pistons? I have this tool and it is actually made of metal. Is this the reason why you prefer to use plastic tyre lever?
I’ve always used tire levers and never felt the need to get the tool.
I think i need to replacement my seels in my sram guide rsc how do you know ? My wheel has resintance and piston don't go back far enoug
Try bleeding the brakes. Worked for me.
Clint, aby suggestions how to fix this problem: Thread on SRAM Guide RSC rear caliper is worn out. Other than replacing the caliper any suggestions? Bolt through the caliper with a nut at the end? Thanks
Hard to understand fully without seeing it, but typically the bolt goes through the caliper and into the fork or frame. For stripped threads, wherever they are, you may be able to use a helicoil.
@@ClintGibbs helicoil it is! Thanks!
I have a problem when i descend in the corners or when im climbing out of the saddle my brakes rub. When i push the bike on to one side and it "dings" and than the other side and "ding" again. I hope my explaning was good enough. Plz help
They just need to be centered.

Man I got a new rotors and new brake pads and I can’t stop them
From rubbing not matter what I do. I got new rotors thicker one from trp 2.3mm and I’m wondering that probably my sram codes rsc don’t work out with the type of rotors 😊
Cracking
I did this with my dot brakes and the pistons didn’t go back in. I would push one in and the other one would come out.
you ever have the issue where everything's centered perfect when spinning or riding straight but when turning or standing/climbing the wheeling rotor flex (while off the brakes) and the rotor pushes over into the pads (while they are still aligned perfectly)
Yes. That usually happens when there is not enough space between the pad and rotor and a little bit of flex will cause the pads to rub. Do the method of relieving some pressure out of the system like a show in this video and it may work for that.
Also, could the thru axle adaptor end caps be the wrong size on the new Roval wheels? I just put my stock Vision front wheel in and it works fine
Never heard of that but I guess it could be!
@@ClintGibbs
In this video, he uses a shim for the rotor to help the rotor to center as well?
ua-cam.com/video/evlL0rg4CKE/v-deo.html
In the past i know you've mentioned you're not a fan of sram brakes at least in the front because the clearance is tight. Im finding this to be true as well. Would this procedure help with the tight clearance?
Absolutely
Yes
Hello, I have an issue that I'm hoping you'll help me with. The brakes are shimano tiagra hydraulic. I have one piston that doesn't retract fully and after centering the rotor I can ride for a bit without any issues and then usually by the end of the ride, the pad is rubbing again and sometimes preventing wheel from spinning. I have given my bike to my local mechanic twice now but same issue. I can't find any new calipers in stock too so I'm wondering whether you have any ideas that I could try myself. I haven't ridden in 2 months because of this :(
If you are going through the process of unsticking the piston, that is really the only thing you can do. Of course you need a center of the brakes after that. If it keeps happening it may be a warranty issue.
@@ClintGibbs thank for the answer! I have cleaned the pistons and did the push back and forth quite a few times. When both pistons are pushed all the way in and the brake is applied the left side won’t go out at all unless the other one is held in. Pretty strange
Hi ! Hoping someone can help , my breaks/ ( not hydrolic) my rear pads and my disk are getting extreamly hot , set of on my comuute this morning and I could lock up the rear wheel however on the way home my rear brakes were about as effective as a peice of chocolate , bit confused got new pads and rotor on the way but need to commute for a week, any tips?
New pads need to be seated in. Basically you do about 10 hard stops from about 20 mph, not quite coming to a full stop.
Nice videos but there are other issues that you haven't covered. I had an issue with brand new Shimano brakes.The pads wouldn't stop dragging. After trying everything. I opened the bleed port on the lever and expanded the pistons outward. A little fluid was expelled but that did the trick. It was almost like it was overfilled.
I actually did a dress that in this video, especially starting around 2:50
