The pistons in the caliber are not disengaging all the way and the result is that the rotor is rubbing on the brake pads and the wheel can not spin freely. I noticed this problem a couple weeks ago and I took the caliper apart, cleaned it, reassembled, and bled all the air out of the system. Worked great for a few rides but now I am back with the same situation. WTF? I also noticed that my front rotor has some free play where the ring style fasteners attach the two pieces of the rotor together. I'm thinking this might be the source of the problem. Is there a way to tighten these up? Anyone else ever have this problem? Your feedback is much appreciated.
