How To Fix Noisy Squeaking Squealing Disc Brakes On A Bike

- I show the steps to repair the squeal on a bicycle disc brake. The most common cause of screeching disc brakes is dirty, contaminated rotors or pads. Usually cleaning them will solve the problem. But if the pads are contaminated with oil, then the pads will need to be replaced.
I often get asked what can be used instead of alcohol. I do not know. Isopropyl alcohol is the most thing to use to clean bike disc brakes. There are some specialized bike disc brake cleaners such as Finish Line Bicycle Disc Brake Cleaner. www.amazon.com/exec/obidos/AS...
Anything else, may or may not work. Anything else, may or may not ruin your brakes. Do not use automotive brake cleaner. It may ruin your brakes.

When sanding the brake pads, lay your sandpaper on the work surface and rub the pad on the paper. The way you do it can more easily lead to an uneven brake pad surface.
I just got my wife into mountain biking, and I converted the wheels on her new bike to tubeless (didn't go smoothly). When I put the wheels back on the front brake squealed like a banshee. It was unrideable. I watched 3 videos on how to cure it and your video looked the most reasonable for my situation. I followed the steps you outlined exactly and now it's quiet as a mouse. Thank you so much!
I actually just poured a bit of isopropyl alcohol on the caliper and went for a ride, worked pretty well. The squeal doubled in intensity for about 2 minutes but it was fine after that. The friction from braking and the air from the disc spinning must have helped to dissolve the contaminants and dry it out.
Cleaned the rotors and pads as suggested and sanded the pads too, and now no more squeal, thanks RJ‼️🚴♂️
This is awesome! took my rear breaks from a loud shriek down to a very manageable whistle ! thanks for the tips!
This video solved my problem. Remember to do the break-in, after 25 to 30 break cycles the noise disappeared and the breaks started breaking much better than before.
Life saver, my rear break was as loud as a trumpet, until I applied rubbing alcohol to where it is silent. Cheers my guy 👍🚴❤️
My brakes were perfect before I removed both wheels for truing. Put wheels back on and had the turkey gobble on rear and slight squeal on front. Found this video, removed and sanded pads, cleaned rotors with acetone. Brakes are now perfect again.
Just cleaned my front rotor. No more squeaking at all. Thanks mate!
Thank you for this video! So helpful!
This helped me so much thank you!! Keep inte up bro🤗💸
Thanks for the tips, the torch truck worked great!
Instructions weren't clear. I went to my garage and lubed my discs.
Also check the rotor and look for its wear limit. Magura rotors for example has a limit of 1.8mm. if its thin like below 1.8mm then you should replace it. Worn rotors can produce a squealing noise also
The shop I work at we lightly sand the rotor and pads, douse in rubbing alcohol and burn both the pads and both sides of the rotor for about a minute. This method works pretty much 90% of the time except if the pad is basically dripping oil because they do absorb it.
Thank you for the clear processes of troubleshooting my brakes and the bicycle dad joke!
Thanks man you just helped out a lot
This video helped me out a bit found out how dirty my one disc brake was.
This will be my job for the weekend.
