Disc brake noise
« on: May 21, 2007, 12:19:39 PM »
Am I the only person that has disc brakes that squeal? I have a full suspension bike and if I adjust the brakes for the feel I want they start to squeal after a bit of riding, especially the back brake. The rotors don't seem to be warped or anything. I've tried to realign the calipers but still get the same thing. I even took it to a shop for a tune up and get the same thing. They are Avid BB7 mechs, same pads that came with the set. ???

How are you adjusting them? I've found on my Avid mechs that if the inside pad is too far in it'll make them squeal. When I have it just right they don't squeal at all.

the hydraulic brakes are a little different in that both pistons will move, but on the mechanical brakes only the outside moves and it flexes the rotor over into the inner pad. So it makes them more sensitive to being adjusted. But I agree, if adjusting them doesn't help, or you have them right already, then switching pads can help. I know I need to find some different ones for my Marta's, they howl like a dog sometimes, and when they do that they don't stop for crap!

Yes I have found that if I back off on the inside pad it goes away but then I have to grab more brake lever that I think I should. Of course it's the back brake so it's not to bad if its a bit soft. I may try some organic pads and see what happens. Anybody try one organic and one semi like mentioned in MBA?

Have you tried turning the outer pad in some to compensate? Or try tightening the barrel adjuster some at the brake lever. I have mine where I barely have to move the lever and I have brakes. It can be a pain though because the rotor has to be dead true to run them that close.
