Thanks Wasabi, I realize now that I got a little trigger happy sandblasting before dissasembly like I did with the one caliper. I do plan on tearing apart the other before blasting and doing a full rebuild with new seals all around for everything. I can agree grit getting places it shouldn't be as I've already found some after removing the piston. I'll do a full cleaning and lube of everything and if I don't think I've done it right I'll buy refurbs. I'm doing all of this as a learning experience but in the end I'd rather be alive than experienced.
