How to Clean Disc Brake Pads and Rotors - STOP BRAKE SQUEAKING!
ฝัง
- เผยแพร่เมื่อ 17 ส.ค. 2020
- Here's the technique I use to clean squeaking disc brake pads and rotors when they are contaminated.
3 things you need: disc brake cleaner, a clean rag and some very fine grit sand paper or wet and dry paper.
-Remove the wheel then the pads.
-On one pad at a time closely spray disc brake cleaner onto the pad to loosen the dirt and oil.
-Wipe the freshly sprayed pad back and forth on a clean rag to remove the dirt that you've loosened.
-Spray and wipe the pad again until the amount of dirt being wiped on the rag is minimal.
-Put the wet and dry/sand paper on a flat surface and rub the pad gently in a circular motion to remove some material and bring out the fresh layer underneath.
-Wipe away the dust on a clean section of the rag.
-Thoroughly spray both sides of the rotor with disc brake cleaner then wipe dry with a clean rag to remove the dirt and oil. Repeat this process until the area of the rag used to wipe the rotor shows no signs of dirt.
-Re-install the pads and wheel and check the caliper alignment.
-Bed the freshly cleaned pads and rotor back in by performing several stops on the road....cycle at speed and brake to allow the bike to slow to walking pace.

Thank you for creating a Fluff free how to video.
Thank you. Helpful. Concise. Surprisingly not everyone on youtube is a pro cyclist. Who knew?
9/10 video as it shows all the steps, but NOT how it sounded AFTER the fix. I too have a bicycle with a baby elephant screaming in agony when I apply the breaks - just as in the intro of this video - but I would have liked to have heard proof that it actually did anything.
WIll try this later today and I am quite confident that it will do "something" - atleast untill I get a set of new pads in the mail.
Well. What to say?
I did the brake-job and started with the rear and I was amazed by how well it worked. It was quite a mouse and spurred on by this success I did the front. Assembled everythng and tok it for a short ride aaaaand... it howls like a baby elephant beaten around the trunk with a screaming banshee.
The old brakepads where horrible before I cleaned them, but after brake cleaner and sanding them on 800 grit wet/dry paper using alcohol they looked like new. Cleaned the rotors and there was no more black that came off of them and they felt like they were new.
So, what gives?
What I hear is one thing, but when it howls you can also feel the whole bicycle vibrating between the legs so is this some clue to what else this could be? Rotors seems to run true and the pads are really gripping and biting into them and the stopping power is really really good.
Any ideas?
@@GoingShirtlesshi im not sure how bikes work entirely, but maybe your break isn’t centered so when the wheel is attached it may be grinding on one side. As far as how to adjust it, i have no clue. But thats something i saw in another video’s comments as I need to do some maintenance myself. Also hope you figured it out otherwise in this 9 months, but if not please feel free to share what it was cause i have the same problem.
@@GoingShirtless So you're saying it worked really well for brake performance, but they've gotten load AF? Did it go away with time?
@@RadoHudran Sadly no,. They brakes are grabby as hell but they are stil quite annoyingly loud. It is hard to pinpoint the source of the noise as they do sound different now and I feel this is more a vibration than the actuall pads making the noise.
I wonder if there could be something done in the way of decoupling the calipers from the frame by adding a rubber o-ring or just a piece of old innertyre tubing fashioned to be a spacer of sorts.
Did you try sanding the disc break?
What does bed mean? I not the bed u sleep in. I mean the last step in this video. What does it mean
i think it meant like to test them
Ty@@mart4144
what if I don't have sand paper
Very good. Thank you!
This is very useful
Thanks
So so so important to bed in carefully!!! I glazed hundreds of pounds worth of rotors on the back of bad advice!! Slowly and gently team!! Slowly and gently!!
what does that mean "bed the pads"?
@@ernis.e kinda like "breaking in" the pads. You gotta get up to speed about 20+ kmh and then slowly pull on the brakes so that initial layer of brake pads wear off and kinda get used to the rotor surface. It's very important because down the line you'll get uneven braking. I've been there just a few weeks ago. Dont rush in cleaning your brake pads and rotors!
Thank you for your advice
Nice thx! Ive seen that some suggest to sand the brake rotor 2. And what grit for sand paper? Ive seen 120 but this one look like 1500 lol
@@deadbabyjokes5319 I got like 800 or something, finest sand paper at bunnings really.
Useful thanks
Would have been nice to hear the results after the cleaning.
Wet clean Discs scream horribly.
It wasn't shown because it doesn't fix the problem. Get a can of CRC DeSqueak and that will fix it 100%.
What grit sand paper should I use
I expect a 250 grit sand paper. Or a fine grit for 3M sand sponge
Fot the rotor itself can't you just use a degreaser. Thanks.
Thank youu ♥
Do you think that pro teams do not know all that. In torrential rain, disc brakes scream horrendously. I have the recording.
I found this video helpful and didn't really know "all that". Then again, I'm not a pro... If you're a pro but looking on TH-cam, you're not a pro.
Can it be done with WD40 for cleaning?
no
HELL NO YOU WILL KILL YOUR BRAKE
No ! WD40 is not good for this. Use a brake cleaner.
What spray
Could be isopropyl alcohol 70% or a disk break cleaner
This is fake, I use alcohol 100% for cleaning rotor and my brakes dont work, what to do?
Now if i press the brakes it doesn't stop the vehicle 🤣 it simply moves
Mine is always swueaking even it has no contaminants 😂
It might be too tightly adjusted.
@@Hjernesprengwhat do you mean?
Don't spray so much. One short spray is plenty enough. You need to clean it mechanically afterwards anyways and many brake cleaners are toxic.
Cleaning like this doesn't stop the squealing. All you need is a can of CRC De-Squeak and it will fix the problem.
0:06 what tool is that?
a screwdriver
no need, just use a wet clean cloth, clean it everytime after riding. its all fine.
Just buy new pear they are cheap
