Thanks for the info. I know the piston rides pretty much on the O Ring but wasn’t sure if there just needed to be a complete smooth surface. The fluid probably needs a smooth surface also I’m guessing just to form a good pressure on the piston. Probably just get replacements and keep originals to maybe sleeve sometime. I’ll have to most likely eat the core charge too. Do the numbers on the calipers indicate a date code? If not then I’m not worried about keeping them. Thanks again
