I know this topic has been beaten to death, but I have to figure it out. I able to tollerate my sqeeky avid disc brakes when Im riding trails on my own, but riding with others around, it pisses me off. The longer the ride, the increase in the noise level. Ive cleaned the rotors, I even have a second set of wheels with a set of off brand set of rotors and the same thing. Do I need to change the pads, could they be worn out? Its not pad adjustment, Im now a pro at the adjustment. What the hell!
