well, I want to disassemble them, clean them up and powder coat them (I just bought a home powder coating kit !!! Woo-Hoo!), but then I need to put new seals and all...and it never seems to fail that they will leak between the 2 halves...and yes - I replace the o-ring ! I must be doing something wrong...

If they are remanufactured stainless steel sleeved, and you have gone the whole process of seperating, cleaning, honing the bores, etc, make sure you're not putting the lip seal on backwards (if you're using a lip seal). If you're using actual o-ring style seals and the pistons are clean as a whistle, your bores are toast more than likely.
You really, really need to have a perfectly working brake system. Its why I'm not driving my 'vette at all. The pedal on the right doesn't mean much if the pedal on the left isn't working.
Good luck & be safe.

I agree...no brakes = no Vette.
Not sure if mine are sleeved...when I seperate the halves, I should be able to see the sleeve material opposed to the cast material - yes ?
As for the lip seal, which way is correct - cup pointing into the bore or pointing out ?

I've never seen a set of sleeved ones, but I would imagine that the sleeve can be disseminated from the caliper casting.
On lip seals, the lip points into the bore so that the fluid expands the seal snugly to the bore walls under pressure.
I don't know if corvettefaq (http://www.corvettefaq.com) is still around, but if so, I'll bet there's a good write-up on there for caliper rebuilding. Rebuilding is one of those things that to you, me, and the rest of us seems so easy to do that maybe there's something we're just overlooking. But if not, I'd bet its just the negative benefits of having sleeveless castings.
