Watch out for the small o-rings that go between the caliper halves. You'd be surprised at how many don't see/notice those little turds!
Clean them well, hone if needed. While ya got them apart, take the bleeders out, and run a wire down thru the hole to make sure it is clean, all the way thru the caliper(it'll make sense once you see it
).
If the caliper bores are corroded, don't even bother with trying to rebuild...it won't work. The pistons, if corroded can be replaced, but the bores can't be honed if they are corroded....
Good Luck
