Andre Meyer Posted August 18, 2014 Posted August 18, 2014 Hi Guys I have been battling with brake squeal for quite some time now and have noticed that many other riders complain as well. It became so bad that I sometimes avoided rides with friends because of the excessive noise. I tried all the advice. Cleaning and sanding and even burning of brake shoes and rotors. Realigning brakes. You name it. Ended up buying new brake shoes and rotors. Same noise!!! I then took the brake shoes out and sanded them on the back of the brake shoes where the paint is until they were smooth. I then polished them with braso until smooth and shiny. I then applied a very thin layer of copper slip and "Wallah". No more brake shoe squeal. Hope this helps.

worriesnot Posted August 18, 2014 Posted August 18, 2014 "sanded them on the back where the paint is"? and you say that worked?interesting... which brakes you have?
NINER_boy Posted August 18, 2014 Posted August 18, 2014 (edited) Also, clean or replace your rotors. New / clean rotors with sanded and clean brake pads should not leave a squeal.PS, remember you need to break them in again after all this cleaning. The Webcol acohol swabs work a charm If after ALL of this you still have a squeal, there is something else on your bike that rattles under braking. Hop you find the source of troubles soon Edited August 18, 2014 by NINER_boy
VaderZA Posted August 18, 2014 Posted August 18, 2014 I had the same problem on my Avid CR's. Solved it with a little bit of copper slip on the BACK of the brake pads, so between the metal part of the pad and the calliper.
Andre Meyer Posted August 18, 2014 Author Posted August 18, 2014 Did so but hard to believe the noise was generated by the contact between the brake pistons against the back of the brake shoes and not the contact between pads and rotors. The way to test this is to spray a bit of water on the rotor. If the brake squeal subsides then the problem is between pad and rotor. If the squeal persists the problem is between the contact between the back of the brake pads and the brake caliper pistons. worriesnot 1

VeloErv Posted August 18, 2014 Posted August 18, 2014 have a look at the embedding process that all brake manufacturers suggest. follow those instructions and you'll end up with less chance of noisy and poor performing brakes.
