Refinishing 4 piston calipers, any experience? Options

[davep]

I just picked up a pair of 944 Turbo calipers that need a bit of work. This is the first of these calipers for me to play with. While the early 911 "S" caliper is aluminum, and I have several of them, they are bare aluminum with no protective finish I have noticed. These Turbo calipers are a lot different. They are painted and plastic dipped. The plastic is peeling off in places. Further, there are plates that fit on either end of the pads that are fastened in place with Allen key bolts. To separate the caliper halves, the 4 main bolts must be removed, plus these bolts and the cross-over brake line. The bolts inside look like they will be very difficult to remove. The plates themselves look like stainless steel.

So, any tips for disassembly?
Any tips for cleaning & refinishing?
What is required to install on a 911 strut (bolt spacing is wider than the 911 "S")?

The rebuild lits can be got direct from Brembo.. or through a place like Hoerr Racing.

they sell seals, dust seals, bleed nipples etc, you just need to know which size pistons.

The allens zip right out with an impact and a good allen.

To properly mount them, the calipers should be machined and made radial mount. You can also get away elongating one of the mounting holes

The allens that hold the halves together may come out that way, and I'm not worried about them. It is the little ones inside that hold the stainless plates in place that worry me. Just measured the pistons: 28mm leading and 30mm trailing. Supposedly from a 1988 951 (944 Turbo). Some of the pistons are sticking, but moving. Some of the dust seals are toasted and brittle. I found some places that sell separate parts.

To bad the motor city site doesn't include the wasser-pumpers.

I have some Craftsman Allen key sockets that are decent quality, but I may see my Snap-on guy again. I found some old Snap-on screwdrivers with bad blades; and got new blades for free. The one was so old (40's or 50's) he couldn't get the exact blade for it.
