While I have my caliper off, I was thinking about rebuilding them. I found this article where the guy rebuilds a Willwood caliper. Does this seem like it would work for our 996 calipers? Can I follow the same procedure?

And anyone know of a place to order a rebuild kit for the calipers?

 

For the longest time parts were not available for Brembo brake rebuilds. Now you can order directly from Zeckhausen.

Assuming you have the stock brakes, you will need:
2X 40mm kit (front)
2X 36mm kit (front)
[your car has a 40/36 setup, which means you have 2 40mm pistons and 2 36mm pistons per caliper. So you will need 1 40mm and 1 36mm kit per caliper, or 2 of each kit for the fronts.]

2X30mm kit (rear)
2X28mm kit (rear)
[you have a 30/28 pistons on your rear, so you need 2 of each kit]

You should check your caliper part numbers and then confirm your piston sizes, just to be sure.

The link you posted will work as a template. But, here is the pelican writeup, and here is a writeup from Rennlist on how to do it. Both will require a little adaptation for your car, the Rennlist writeup is closer to our setup. So, I put the text of the writeup below.

=======================
Rennlist Writeup
=======================

The Process for S4 four piston calipers with dust boots and seals:

Removal/Disassemble
1. remove calipers from the vehicle
2. using compressed air, blow one piston out of the caliper at a time as you hold the other three in with blocks of wood and c-clamps. use a block of wood set into the caliper to capture the piston you are removing and keep it from flying out, watch your fingers. keep your pistons organized and make sure they go back into the same cylinders they came out. clean before reinstalling.
3. once your pistons are out remove bleeders and the brake line between the two halves. clean the caliper with brake cleaner.

Clean/Strip Anodizing
4. use duct tape cut to the appropriate size circles and tape off all four cylinders. plug holes with bleeders if you plan to replace or use 10mm grease fittings. keep the aircraft remover away from the cylinder walls and caliper internals.
5. use small disposable brushes to apply aircraft remover (Klean Strip) to the calipers, cover liberally, the anodizing will imediately start to bubble off. wear rubber gloves and eye protection when using the remover.
6. after the caliper is completely coated and the stripper has worked for half hour to an hour take them to your local car wash and spray them down, again wear eye protection and rubber gloves.
7. back home, remove tape and spray down again with brake cleaner, let air dry. a brass brush can help get the last bit of anodizing off. repeat 5-7 if necessary.

Refinish
8. use 3M blue painters tape to tape off cylinders again and plug the bleeder and line holes.
9. use wire to hang calipers and paint with high temp caliper spray paint.
10. i used a flat black paint and hoped to keep a matte finish but the high temp clear coat gave them a slight sheen.
11. after dry bake in over per directions

Rebuild
12. using your fingers, coat the cylinder walls with fresh brake fluid. brake fluid is hard on your hands, wear latex gloves.
13. dunk seals in fresh brake fluid and install them into the grove in cylinders making sure they do not twist.
14. dunk piston into brake fluid and slip piston into the cylinder until it binds against the seal.
15. slip dust boot onto the piston and into the grove.
16. you will use a c-clamp to press the pistons into the cylinders. i cut wooden dowels just slightly smaller in diameter than the cavity in the pistons about an inch long so they were just longer than the depth of the cavity and stuck out far enough to get a c-clamp on them. slowly use a c-clamp to press against the wooden dowel and a wooden block on the back of the caliper to move the piston into the cylinder. it takes very little effort to press in. if you feel the back of the piston catch on the back lip of the grove for the piston seal simply back off on the c-clamp half a turn, re-align the clamp and turn in again. it was quite common to catch the grove and i had to constantly back off on the c-clamp and try again. once you get the first one in you will get the feel of it and the rest will be a piece of cake, just don't force the first one or you will damage the piston.
17. once the piston is all the way in use your finger to press the boot into the grove in the face of the caliper. wipe away access fluid.
18. repeat steps 12-17 for each piston...

 

Thanks td. Great help
