"Rebuilding" 98-02 Calipers? I just picked up a set of 98-02 Calipers for my '95. I plan on swapping them onto my '95 with a C5 conversion brackets/C5 calipers, so I am going to clean these up and paint them.
I bought these used (obviously) and was wondering if the rusted drums on the inside of the caliper are an issue? I plan on taking a dremel/wire wheel to the entire caliper to clean them up before painting them, so I can "clean them up" (the inner drums).
Also I've heard of people putting new rubber boots in these, where can you buy a rebuild kit for these?
Thanks!

Alright, I did more digging and found this:
http://installuniversity.com/ls1/ins...r-rebuild.html
My question now becomes:
Can I disassemble the calipers to inspect the internals, and put them back together (without a rebuild kit) if nothing is damaged? or is it that once it's apart, you need a rebuild kit? It would be very nice to take the calipers apart to clean everything, but I don't want to purchase rebuild kits if not neccessary.

the rust on the pistons you see externally is normal. as long as you don't see any huge craters i would not worry about them too much.
disassembly is pretty easy, like described in your link. you should have no problem popping the pistons out to inspect then reinstalling with the original seals. just use new brake fluid to lube the seals first before installing, and since you bought these used i would pull them apart to check.
I thought i saw caliper rebuild kits as in new seals on summit.
and i think you can buy/rent a caliper honing tool from local parts stores if you wanted to "fully" rebuild them but i wouldn't recommend it. you can turn these in as cores and get clean reman'd calipers for less. also be sure to inspect the slide pins and grease those well is brake caliper grease.

I called the local auto parts stores, and remanned calipers are $43 a side + a core, so if they would need a full rebuild on each caliper or I find any "damage", I may consider that.

I've seen far worse than that on cars around here 
Those really don't look that bad at all really. They're just dirty and that rust is purely cosmetic on the outside and easily cleaned up. Even if it leaves some slight pitting it won't matter as that isn't in contact with the bore.

Started the "clean up" tonight. I started with one of the Caliper Brackets. I'm not finished with it yet, just got a good start on it (about 20-30 minutes of work so far including changing the dremel head a couple times). The bracket above was the cleaner of the two brackets when I started.
Sorry for the picture quality, lighting was messing with the camera for some reason, but you get the idea.

Do you have pics of your C6 setup?
