I've installed plenty of rebuilt calipers in my time. Was a ASE Master mechanic for a while. I've seen some nice rebuilds and some real chity stuff from NAPA, Advanced Auto, and the rest. I've had to take new rebuilt calipers apart to see why they wasn't working. I've found cig butts, metal shavings, broken seals, wrong size pistons, missing seals, wrong size bleeders, you name it. It's not uncommon for a rebuilder to remove names on the parts. I have yet to see a rebuilder recoat the bore in a caliper. Too much time and money. A quick hone to smooth out the wall and that's it.
