Having read all the threads about changing rotors and pads, and viewing several youtube videos, I felt I could handle the job. Have new rotors, pads, anti vibration shims, all new hardware from Pelican. Plunged in yesterday, all went well until I encountered one of the anti vibration pucks stuck in the caliper. The others came out easily, but one seems frozen. In attempting to pry it out, I broke the thin metal shim connecting the two pucks, figuring I could rotate it and break it free. But no luck. All other parts showed little corrosion, and came apart easily, even the phillips screws holding the rotors. I will try to get a phillips screwdriver in there and try to rotate it, but...i wonder if stepping on the brake pedal would push the puck out of the caliper, or has it been frozen for some time? Any suggestions most welcome, as I am stymied.
