Installed the caliper...bled the brakes....good pedal...stops OK....it appears that one piston retracts fully but the outer piston does not return in completely like the inner one? Is this an issue? I'm using new pads and the rotor does not spin as freely as I would like but this just might be because the pads have not worn in yet. Was there a post describing the best way to break in new pads gradually?
