Uneven Disc Brake performance I'm using Hayes CX-5 Mechanical Disc brakes with Avid The G2 CleanSweep Rotors on my cross bike. I believe the Pads that come stock with Hayes CX-5 brakes are semi-metallic. I'm experiening uneven braking, it's really a pain to feather my braking to slow down because of this. It seems that the brakes engage on parts of the rotor, but seems to slide more freely over other sections. I wind up over braking to slow because of this. The rotors are a month or so old and do not appear to be visibly bent at all. What is causing this? How can I even out the performance of my braking?

You say the rotors are relatively new. Have they been bedded in properly? The usual procedure is to get up to about 30km/h, brake hard until you almost stop, and repeat. You should feel the braking power picking up each time you do so.

The bedding in process transfers some pad material to the rotors - this is what the pads grab, rather than the actual steel surface. It should be done any time rotors or pad compounds are changed.
