I have them apart and the usual rust and pitting was present. I cleaned and smoothed it and basicly runined it by changing the shape of the piston a hair. Should I just slap it together with new seals and test it or bag it altogether for rebuilds at $50 each? I don't care if I have to replace them after this new set of pads is shot, re-using the rotors since the pad still were about 1/8" to 1/4".
