Brakes squealing BB7's. If you have the Avid scalloped rotors that are 165mm this is very common. I did a lot of research on my Juicy 7's when I couldn't shut them up. If you clean them extremely well with acetone, disc brake cleaner, etc., they won't squeak for about 15-20 minutes. If you switch pads, they will be quiet for 3-5 rides. The local LBS in my area was switching the rotors. Now with the G2, second generation rotor, most of this can be avoided. Make sure your brakes are lining up on the rotor and not hitting the thin spokes inside the rotor.
I finally shut mine up by switching to a 185mm G2 rotor. Didn't even put new pads on. Have been successfully torturing them ever since. They will squawk when wet once in awhile, but not all the time.
I love my brakes now, use only 2 fingers braking and really rip it up. By the way, to switch rotor sizes all you have to do is change out the caliper brackets. I made the change for less than $100 and bought everything I needed off E-bay. P.S. the BB7's are one of the most adjustable disc brakes out there. I love the system.
