Avid disc brake truing: am I the only one with this problem?
I recently bought a Avid bb7. The rotor that came with had +/- 0.030 runout, and even with the Park rotor truing tool I couldn't come close to truing it to a point where the caliper pads could be run all close together w/o rubbing the rotor. I then bought two Avid rotors from a local shop. Both out of round. The shop employee said it's the norm for (Avid?) rotors to be out of round out of the box and for truing to be frequently necessary, but Park says that it's usually better to simply chuck a non-tru rotor and buy a new one than to be take the trouble to tru.
Am I the only one with this problem? I don't think I'm setting up the brake wrong. The instructions on the Park website seem pretty clear. And even if I'm setting up the brakes incorrectly, I can see with my wheel truing stand and a dial indicator that the rotor has signicant runout.
