I watched another yt video before this, tried cleaning them with a toothbrush, didnt help. Couple days later i watched this video and cleaned them "several times" until the pistons would come out evenly and pushed them back in with a toothbrush. I didn't have a shimy so I made one from some thick paper and now it's finally running good enough. I could clean them perhaps several more times to make them even better but for now this helped a lot. This guy is a goat.

The "squeeze the brakes and tighten the bolts" trick seems logical but doesn't work, I had to spin the wheel and hand adjust the brake housing until I didn't hear rubbing anymore, then carefully tighten bolts

That's caused when the two pistons don't retract equally into the calliper, known as a sticky or dragging piston. Both the lever vacuum, and the pad spring will apply a shared load across the two pistons. That shared load will always follow the path of least resistance. The piston with the least resistance will retract further into the calliper than the one that drags, resulting in the other piston protruding. This can usually be overcome by cleaning the sides of the pistons with brake cleaner and a cotton bud. Chances are, your rubbing problem will return, so you may want to try this.

@thebrunoserge Agreed, it won’t be dirt. That is most peculiar, a new bike shouldn’t be doing that. I would recommend you check that both pistons are retracting fully. That check is easier done with the wheel removed. If they’re not retracting fully and equally, then you may want to speak to Canyon about it.

First of all, should it move? Some very cheap brakes only have one moving piston. If you’re sure it should move, then hold the apposing piston back, and pull the brake, that should get it moving. Careful though, it may end up moving too far!

My wheel appears to wobble. Would that be the cause of disc rubbing? Or can a wheel wobble independently from a disc rubbing? My bike was shipped to me for some assembly; I heard that the disc brakes can be damaged in transit. I could see the wheel wobble when I took my first spin, and I could hear the mechanical disc brake rubbing at the same time. My powers of observation were not strong enough to tell if the two things were in sync, but I have ordered a spoke wrench and the tools you noted to try an adjust the situation myself--just as soon as I understand.

Allow me to add one more cause of brake rub. Pertaining to Sram AXS: my Red AXS brakes began to rub after running them about 1000 miles. This occurred several times after bleeding and new/used pad installs. What happened? Well, to the best of my ability to troubleshoot, the issue was in the adjustment of the contact point and lever reach adjustment system (as it only occurred on the right lever. Looking at available schematics of the AXS levers, it appears both screws are part of the brake fluid reservoir piston, with the top contact point screw rotation moving the piston up and down, and the lower reach adj screw moving the lever in and out in relation to the piston. So, the both work on opposite ends of the hyd piston in the lever. Sram says to back out the contact point screw when bleeding. I found that in order to eliminate brake rub, I had to run both the reach and contact screws through their full adjustment several times after bleeding (and after suffering from mid ride brake rub) and while doing so, I encountered a sticking point with the reach adj screw - almost as if there was excessive Loctite on the reach adj screw threads. Since using this method post brake maintenance, any mid ride brake rub has gone away. Also, I found it critical not to swap left/right pads if removing and replacing again for any reason.

Mounted the rotors in different positions on the hub and the run out was always at the same postion of the hub, not the rotor. Turns out the machined mounting surface of the hub was out of true. Took me a day of tinkering with dial iindicators, truing stands, etc to figure that one out.

I had a fourth reason pop up on a brand new bike. It was rubbing, not too badly, but rubbing right from the get go. Drove the shop mechanics crazy trying to figure it out. Finally I ended up pulling the rotor off and remounting it on the wheel. Voila, no more rubbing. Weird because it wasn’t loose or anything, properly torqued, but it somehow managed to get a little cockeyed to create rub. I’m finding I have to remove and remount it every once in awhile as it gets out of alignment over time with use.

Good point, viffer94. This is more of a problem for the older skewer style quick release bikes, thru-axle does a better job. I always recommend putting the bike on the floor with the wheel loose, leaning on the bike to add weight, and then doing the wheel up. You then align the caliper to that. Then, in the future, if you take the wheel off, you just need to lean on it when doing it up for perfect alignment. Thanks for your thoughts. Jon

Great video! I'd rather see the pistons of the brakes bottom out in their original set position. Using the spacer and loosening the housing might only be reading a warped rotor. On a side note: Shouldn't you check to see if the rotor is true first? What if you try correcting it by loosing off the piston housing and it reads where the warp is? I know this is likely not going to be the case because of the low chances but it would be as simple to check for the warped rotor first.

Hi, That sounds very annoying, especially with new kit! The question here is to work out what is causing the rubbing, is it misalignment, or is it sticking pistons? If it's new components, then the chances are, it'll be a bleed issue. Also, facing is rarely something you need to do on a used bike. Facing is usually needed post-production of the frame, to tidy and straighten the mounting points. If I were a betting man, with the information I have, I'd say the pistons were not returning in. It may be worth double-checking the hoses for air. I did a video on brake bleed, it's here: kzbin.info/www/bejne/m3jGnZSsqdCif8k

While this is a good video covering all the points, these are just temporary fixes. Rotors warp again under heat, pistons clog again, especially with metal pads, etc. etc. Even with perfectly clean and adjusted brakes you get a little mud or sand grain wedged between the calipers and disc and it rubs again. ☹ Forgot to add: the permanent solution is to just ignore it. Eventually it goes away.

This is the trouble with disc brakes, they're good, but also a pain in the ar$e!

Thanks so much for this video. I recently washed my road bike after a day in the rain, I took my brake pads out, cleaned them with isopropyl alcohol and so did with the rotors. Unfortunately, I did not note the position of the pads (left/right, forth/back) and so in my next ride I got a back/forth wobble in the front wheel when braking hard in a decent. Can the wrong repositioning of brake pads cause such wobbles and if so what would be the best remedy?
@ribblevalleycyclist
@ribblevalleycyclist 9 ай бұрын
Hi Dimitris, Mixing the pads up can result in differing pad thickness within a single calliper, and therefore may cause pad/disc rub or a knocking feeling when breaking. My suggestion is to put pads together that look to be of similar thickness. Also, it's worth giving the pads a bit of a clean, check this video out: kzbin.info/www/bejne/en2pgnSrq56Zeck

I have those Hope rotors on one bike with Ultegra callipers and I like them, but my favourite bike has new Ultegra rotors with the new Ultegra R8100 callipers and those are pretty well perfect.

I like the Hope because the floating technology prevents temporary warping when hot. Not tried the new Ultegra yet.

To clean pistoms.. how about using a pipe cleaner? The little bristle-y brush I see used for everything but cleaning pipes? Seems it would easily be able to gently scrub the sides of the pistons and its very flexible as well. And cheap

Love the video! It blew my mind when you grabbed the right lever for your front brake! 😳 I guess my Canadian mind isn’t wired that way. Is it normal for all UK bikes to control the front brake with the right lever? If so, I would have to be careful renting a bike in the UK. 😜

Actually he's wrong on the last point...if the brakes are still rubbing, chances are it's not a brake bleed you need...it's actually more likely that you need your brake mounts faced (aligned perpendicular with the axels using an expensive facing tool).
@ribblevalleycyclist
@ribblevalleycyclist 4 ай бұрын
Just to explain, what Phillip is saying here is, instead of basic routine maintenance, like replacing brake fluid, which, when contaminated with either air or dirt, is universally known to both affect braking performance, and cause brake rub. You should instead cut into the frame with a £400 ($500) tool, that, when used incorrectly, will cause irreparable damage to your frame. Phillip is right, I’m wrong. Don’t check the basic and obvious things first. Be more like Phillip.

@@ribblevalleycyclist I didn't suggest necessarily that individuals without experience use that tool...many bike shops can perform this service for you....and on your point when the brake lines are contaminated with air/dirt usually the brake pads tend to not provide enough pressure to the brake pads to provide proper contact with the disc, so it's not as likely that rubbing will happen (although I suppose the 'rebound' would be lacking, but that slight amount of rubbing when there is no pressure on the pads from the caliper is usually a very quiet noise). Also, most frames don't get a precision facing job out of the factory and are misaligned enough to cause rubbing problems due to an uneven braking surface. Also, lets not insult one-another, it's not constructive and helps nobody.

Hi Sean, Oh, it is. And they're made from really soft steel, and have a flat screwdriver head, so they round off really easily. You can get titanium versions, but they're silly money. Best just use a bit of copper slip, and don't do them too tight!! Thanks for watching, Jon

Thanks, Pirmin, appreciate it. Agreed. If you have a close look at the bike in this video, I'm using floating discs from Hope. This type of disc is amazing at resolving warping caused by overheating. I will never buy any other disc again. Well worth checking them out, but depending on your location, they can get expensive. Thanks for watching. Jon

Campagnolo doesn't rub
@julesjulian75
@julesjulian75 Ай бұрын
That must be why there's ZERO Campagnolo equipped bikes in the entire Tour De France peloton. Only Shimano and SRAM groupsets. The professionals seem to be saying "Campag?NO GO". I honestly don't know why this is, but the fact that the pro teams pick Shimano and SRAM but not Campy is why I went with Dura Ace. Just an interesting fact that I thought worth mentioning. I only discovered this information recently, I was very surprised TBH.

Thanks Blair, glad you liked it. That is a Top Tip! If you're going to town on it, then a cotton tip soaked in isopropyl alcohol is the correct way to do it. Following up with a cotton tip and brake fluid is also a good idea. I was considering doing 3 separate videos, and showing more detail, like you've suggested. But in the end, I went with the condensed version in one video.
