Thanks for watching.
First time I viewed a video mentioning to widen the pad spring which makes sense. Brake rub with these disc brakes only happens with my front tire and it is an ongoing problem. I fix it but it eventually comes back. Rim brakes are so much easier to deal with than these disc brakes. The engineering of the disc brakes is lacking. Hopefully the bike industry will fix this problem. I shouldn't have to constantly have to deal with this headache. Thanks for the video.
I know you put this video out over 5 years ago but wanted to say thanks. I spread the springs with a small screwdriver and it fixed the problem. I don’t think the pistons were retracting all the way back in as I’d get rub for about 10 seconds after braking. Really appreciate the video!!
Watched this video last night... just came back to say that after 3-4 hours of trying to stop a new disc rotor from rubbing, THIS was the information that actually helped me! I followed all your recommendations and it did the trick, can’t thank you enough!
This is the reason why I work to pay my internet bills. Keep it up 👍 sir
Great Shows exactly what I needed. My first time using disks. It was a new bike the front ones rubbed. The video gave me the confidence to try. I surprised myself when it worked so well.
Spot on explanation. To the point with no messing around padding out the video.
Thank you very much.
I just got my road bike. After around 20 years of mountain bike with standard disk brakes . And i did not know how to adjust brake pads on hidraulic Shimano 105 brakes.
Another good impresion for me is that the tutorial is so good even if you don't know nothing you will get it done.Thanks again.
Thank you so so much! What great little tips and tricks there - the feeling when you get that first spin without sound is a real sense of satisfaction! One new subscriber for sure !!
The Tipp with opening the spring of the pads solved my Problem. Many thanks!
this was so helpful after i got new hunt wheels and put new disc rotors and pads. i thought tried everything til you showed to spread out the metal clip. worked to perfection! thank you
Just got my first fay bike last night and after installing everything, this is the exact sound I got. Couldn't figure it out so was planning on taking to the local bike shop today. I'm gonna give this a go.
I found this video to be very helpful after several trips back and forth to the bike shop u have saved me money and time. Thank you!!
Thank you sir. I’m new to disc brakes and having issues with the rear rubbing. Did it up like you taught me and the front is perfect and the rear still rubs. I’m not giving up I hate brake rub…Grrrrr
The spring trick is genius. Thank you!
Thanks for the video, it really saved me. When I bought my bike with my first set of disc brakes the shop gave me a little orange plastic spacer to fit between the brake pads for when I remove the wheel. He said if the spacer is not there and at some point the brake level gets "pulled" i.e. bumped or rested against something, the calipers will squeeze together more than they should, and stay that way. The result is the disc may no longer fit between the pads, or fit too snugly. I take my front wheel off frequently and the spacer does the trick - except when I forget. If this happens to you, the key part of the video is at about 3 minutes when he uses a screw drive to push the pistons back in. I had to push pretty hard, but slowly they went back in, then everything fit again.
Thank you, opening the spring that holds the pads did the trick for me.
Will try the spring trick taswell. Have ultegra hydralics and my problem is not aligning them but that the pads don’t move apart enough after releasing the lever. Maybe 1/3 mm instead of 1 mm. Front break rub when I stand up. Rear is fine.
Was able to solve my brake rub issue by following your video. Thanks!
Thank you so much! This video saved me when I got bad brake rub the night before a big group ride. 😀
Thank you for this. As you said, takes perseverance! I took solid 20mins and several rounds get it just right!
Disc brakes are such a pain in the ass I am seriously starting to wonder if the benefits really outweight the hassle.
Got my first bike with disc brakes. Thanks for the video.
Legend. The only advice that actually worked. Thanks so much!
Just fixed my breakes by the help of your video - thanks ...
This is why Chris Froome hates discs :) Thanks for the vid
this trick whit spring is amazing thanks a lot
Brilliant Mate! Thanks so much...in 5 minutes by brake rub was fixed!
Thanks! Just got a new bike with discs and straight out of the box the front disc has a rub. Tomorrow...
that worked like some sorta black magic!!! thanks for sharing, this and RD video helped so much fixing the bike noise
Very helpful, thank you!!! I had some rubbing after changing the pads and the tip about taking a nip off the retaining bolt and grabbing the brake was a big help, as was opening the spring. Problem solved 🙂
Clear explanation. i aint got no rub nomore. tnx a bunch
Thanks, this was great advice as I had this rubbing issue on replacing my front pads. You are spot on, I did need to persevere and re-try a few times. 'Helping' the spring along per your tip and ensuring the pistons were pushed in to near-flush also helped. Would still not swap back to rim brakes if you paid me!
You're an idiot and the reason we all have to suffer with these garbage hydraulic brakes and all the mountain loads of problems they come with. The average person spends 50% of their time fixing a brake as opposed to riding their bike
Another tip if your brakes squeal like mine did when applying the brake is change or the standard pads, I swapped my standard shimano grx pads for a set of gorilla aluminium backed composite pads, they bite much better and zero squeal.
Widening the pin fixed the problem (105 R7020) .Many Thanks
Not tried bending the spring before. Worked well. Thx.
Thanks for the top tips! Really helped me & now I can enjoy a silent ride again 🤣👍
Thank you from Brazil. Solved my problem
I’m new to disc brakes, tried to upgrade wheels and their rubbing... I’ll give this a go.. thank you
Yeah, removing the break rub on the stand is easy. Not having it reappear when riding is another ball game. On my bike it simply reappears at times and I don't think I can do anything about it except simply learning to live with it, although it is annoying. On the last ride it got really loud on the front wheel at around 80 mile mark, after I think I hit a bigger pot hole, then after about a minute with some repeated activation of the brake lever it went quiet again. I ride mainly flat courses activating the brakes sparsely so no chance of overheating to occur. The bike is new, top brand and top price tag frame set and has maybe 500 miles done so far, with a stock Shimano wheelset with Shimano Ultegra discs.
you are not alone in this....
Same with me, just making a right turn is enough to start disk brake rub on my Wilier with Ultegra disk brakes!
Loose spokes
Thanks, this is a really well made tutorial which has enlightened me as a newbie on disc brakes a lot about solving this issue. Thank you so much.
Amazing pro tip with the pad spring. As we say where I work a true bike veteran
Thanks!
Thanks. I was getting frustrated with what should be a simple task!
Thanks for this, just sorted my front brake
Extremely helpful. Thank you!
Thank you for this video, finally my front wheel doesn’t rub!! :)
Thanks, for the simple solution.
really helpful! - saved me for ride tomorrow
Great video, clear and useful help! Thank you.
Excellent thanks, mine are at that last stage and I was about to start messing with that pad adjustment.
Perseverance. All I needed to hear 😂 thx, great video
Thank you, mate. No rubbing. Finally.
Great advice, perfect caliper setup now thanks!
Dont have the exact same kind of disc brakes but you are a life saver!! My university student wallet blesses you hahaha
Thanks for the video!!!
Nice video. Very helping. It works
Check also that the piston faces and pad packing plates are free of contamination. I think he might of done this without being obvious about it, but if the disc is just slightly warped,, loosening/tightening the calipers at different places on the disc's rotation will alter the centering slightly, possibly enough to 'split the difference' and avoid rubbing.
Great tips. Careful when pushing the ceramic pistons back into the caliper. Park makes a specialized tool for this purpose though I’m sure you could fashion something to work.
Brilliant tip about the pad spring. Thanks.
I wonder how they avoid brake rub when changing wheels on the Tour.
hmmm good question, maybe one more reason why you see more bike changes instead of just wheel changes, besides the speed.
Someone should send this to Froome’s mechanic...
great video thanks. I found skipping straight to manual adjustment with somebody spinning the wheel until I could make microadjustments worked great also!
Thanks for more one very good explanations 👍
thx for this...fixed my problem
Great video but its enough to make me want to put caliper brakes back on the bike!
Quite good. Many thanks.
Thanks!
Thnx fella. These rubs were pissing me off
Works perfect, thank you
Thank you so much for this, completely saved me! Legend.
spot on bike sorted now.Thanks.............
Worked for me. Cheers
Great tip.
Thank you sir! You helped me out
Nice vid mate, thanks 👍🏽
Cheers pal great help👍
7:39 Is there a problem if I don't put this snap ring on?? because I'm trying to put it on and when I finish the grip it kind of opens, it looks like it's going to burst, I have this snap ring on another bike and it doesn't do that, the grip is normal and it makes some very different clicks.
Tried everything on this video and the r8000 rotors seem to be too thick for the r7000 calipers.
no, they are not. the shimano rotors are all the same thickness. and even if they were not, there is much more clearance in the calipers. i am using 2.25mm thick heavy duty mtb rotos instead of the 1.7mm thin shimanos without problem.
you might not have a problem with the calipers, but more with the pads beeing too close.
remove the pads.
remove the wheel.
push the pistons all the way back into the calipers.
put wheel back on.
adjust the caliper by eye so that the disc rotor runs straight in the middle.
put the pads back in.
pump the brake untl it has a bite point again. the pistons will now have adjusted to the rotors thickness.
if your aligning by eye was good, this might be enough to have a perfectly aligned brake. the rotors should not be bent in any direction when pulling the brake. otherwise you can now try to re-align the calipers.
it is best to do this with new (or even worn pads). if one pad is more worn than the other, or one piston moves more than the other, it gets more complicated.
Grx 400 caliper. Pull the brake hard and it wont recentre. The pads dont retract. Clraned the the pistons tried all the tricks. As soon as you pull the lever hard it recentres tighter and rubs. Ever come across this?
you did not show the adjustment on the rear disc brake adjust same on the front so we can follow also. im new and need a steep by steep instruction. thank you.
Hi! Is this a major big deal ? Because my DYU S2 bike is like this I can hear sound in the disc brake rotor touching /rubbing ? Thanks. Pls reply. Happy new Year.
I really like your videos, they saved me a lot of time, grievances and money. I have a problem with my front disc brake, same as you show in the video, new Dura Ace 9170 with flat mount. I have installed the new caliper, new rotor, new brake pads, all centered, rotor is reasonably true. When I riding straight or in the workstand, there is no rubbing. When I am getting out of the saddle for sprinting or climbing, or in the workstand when I turn the handle bar sharply to the left, the rotor rubs the pads. No significantly but it annoys. I tried everything from re-aligning, lubing and execising the pistons, bleeding etc., no succes. Wheels and hubs are also new from a quality brand. Any idea what can cause this or does the brake need more time to settle in?
Think you’ve covered all the bases there! It seems the problems appear and disappear no real logic to them!!
Thanks for your reply. Will check with Shimano, I remeber I read somewhere that they had some quality problems with some production runs of the DA 9170 calipers...
Be interesting to here what Shimano have to say!
God forbid you have a flat. This is why I stick with rim brakes. So don't have to deal with this.
Thank god that there are thru axles which allow to put the wheel back in exactly the same position, so adjusting is just necessary when you set up new pads.
As far as I know there is a certain way to do this with a quick release, but thru axles are 100% fool proof.
Is it safe to tighten the caliper mounting bolts without a torque wrench? I notice you don't use one but you've got the experience to know when you're not overtightening bolts. My brakes are rubbing but I'm nervous of trying this without a torque wrench and damaging my carbon frame.
Fantastic videos by the way; such a help!
The torque setting is 6-8nm for the bolts!
I’m ready to go back to rim brakes now... Ultegra disc brakes suck... constant rub...tick tick tick tick... yes I fixed it... first ride out... started rubbing again... took it to my LBS... “we fixed it”... next ride out... started rubbing again... I’m over it.
PaulHD_ CYC is it that bad?! I was going to buy a disc brake bike tomorrow 😂. These manufacturers are forcing this on us.
if it is a constant problem you either have a piston thats not really going back into the caliper, or bent rotors. the shimano ones are not my favourite either. you can try to straighten them, but from my experience, they most of the time go out of true again after one or two hard braking maneuvers. simpler one piece designs, like from magura or trickstuff seem to work much better in this regard. at least for me.
@@Raptors0524 Having the same problem with my new hybrid, yes on my mountain bike, the the discs meet mud and impact, ive not had a problem in years.
Digi20 rotors are bent due to the heat, especially after downhills when you use the brakes more and for longer period. Most of the times you dont need do to anything about it, on the next ride it usually corrects itself (rubbing stops after a couple of brakings). I hate it as well and tried multiple times to bend the rotor back, adjust the caliper positions etc - after mountain intervall trainings. But I found that these efforts are almost useless - it usually rubs after heavy breakings and usually disappears during an endurance ride.
So in theory Everytime I take my front wheel off (to mount on bike rack) and it rubs I have to do this?.. going back to rim brakes
If the braks rubs then yes you will have to slacken off the caliper and re centre the disc rotor. Or like you say stick with rim brakes and save all the hassle.
@@FreeToCycle unfortunately it's been happening the last few times I removed my wheel aka EVERYTIME
O the joy of disc brakes!
Its no problem with thru axles. but quick release and disc brakes can be quite a nightmare, especially on the fork.
i second Digi20
thru axles make the alignment of the hub and brake axis a lot more consistent . Since ive gone to thru axles with all my disc brake bikes, rubbing has been a non issue. QR skewers and Disc brakes can be a pain in the neck.
This is why I am sticking to rim. Too much drama. But this is a good video
The latest rim brake pads from Campagnolo and Shimano are really excellent and provide all the stopping power any one needs. My Ultegra disk brakes are a constant problem mainly on the front which is constantly going ping ping after I brake!
Spread the spring with a screw driver, problem solved. Thanks!
👍
Great video, I'm hoping that I can replicate what you have done. Typically, would we find that removing the front wheel interferes with the alignment? I wouldn't expect it to but mine may look great in a stand and spin forever but after a ride the pads seem so much closer together. Brakes don't appear to need bleeding - I'm hoping that having a bit of a play with the metal prongs which hold the pads might help. It is so frustrating on new wheels with Dura Ace pads like yours! Part of me wants to sell them and buy a rim frameset!
Hydraulic brakes are the dumbest most retarded thing they ever made for bicycles. Not a single bike has ever needed Hydraulic but they kept pushing them because of marketing idiots working at these bike companies. I sold a bike with a hydraulic brakes because nothing would solve the disc rub issue, I went with a cheaper model and got cheap Tektro Mechanical diskbrakes and its been a dream, can adjust anything with ease that uses a regular cable.
Please could I ask about where it rubs in only one spot when you span the wheel. I thought that by definition that has to mean a bent rotor. How can loosening off the bolts, and squeezing the brake on and then retightening the calliper bolts, solve this? Thank you.
I resorted to using my rotor truing tool to resolve a one point rub - you might be able to average the deviation with adjustment at random points of rotor to eliminate the rubbing noise as appears to have been achieved here but you might also get the rubbing noise back when you load the bike with your body weight
I can manage to get them running silent on the stand but as soon as I put some heat through the rotor it seems to rub again until it’s cooled down. Is this expansion of the rotor? I have the same dura ace rotors as in this video. I’ve tried with two different wheelsets and get the same result. Driving me crazy!
Must be the disc expanding slighty, never had that before it may go away when the pads wear.
No discs are better than my Campagnolo Super Record rim brakes.
Great video, but what a total load of unecessary aggro!!
My bolts holding on the calipers are like the hulk holding them in
You don’t have this issue with rim brakes...your avg Joe wouldn’t know how to fix this. Don’t get me wrong I have a disc gravel bike, find the industry over hypes the tech. Keep it simple ..
M Lee You’re correct in one sense, but not always. Especially if changing wheelsets with different rim widths. Pretty easy adjustment. I will disagree though on the idea of the industry overhyping the tech. There is no better braking, whether be the power or modulation that disc brakes. I live where we have flats, rollers and mountains nearby and can tell you that disc brakes are a wonder while descending. Not only that, the consistency of braking is superior across all conditions.
This is so dumb, omg. I own a disc brake road bike. Would never buy one again, just because if that. Fck that modulation, I want silence
*nice*
My rear is the same as yours here. Did you do the whole thing on the rear as the front?
Yes same process on the rear!
Disc brakes suck! A four thousand dollar bicycle should not require such a waste of time. What a con. I have ridden thousands of miles on rim brakes, never a problem with brake rub nor lack of stopping power.
Thnks!!
Thanks for the good info and detailed explanations. This helped me. I logged-in specifically to like and subscribe and hope that helps you in return.
Thanks!
disc brake in road are absolutly disastr never again
Yeah I just completely took my break off and threw it away I’m gonna go back to the old style. Way too complicated and hard to work on I can’t even imagine trying to work on these out on the road 😬
wow that free hub is silent ;o
It sure is👍
