Caliper Rebuilding
RacingBrake caliper rebuilding application coverage is getting better and better for Porsche, as we get more inquiries and interests from Porsche community.

We have piston sizes from 28/30/33/34/36/38/40/42/44 to 46mm, with 30 & 32mm in height, so chances are we have all the size for your calipers but if you can't find your models/calipers just tell us and we will identify them for you.
RB pistons are machined from solid 304SS bar stock, with thin wall cut process to reduce the weight, having 6 vents to help brake release. The surface is of chrome plated to assure the smoothest movement for modulation and brake control, and for leak free service whether the calipers are under cold winter in your garage, or the hot summer on tracks.
RB's unique yet simple design Stainless Steel piston is all you need to replace a variety of OE type pistons:
The advantage of Stainless Steel piston over OE's aluminum:
1. Better thermal stability (less volumetric change as temperature changes)
2. Better strength & rigidity
3. No corrosion
4. Very lower thermal conductivity - Transmit on about 10% of the heat vs. aluminum, so you will not boil your brake fluid nor would need titanium shims or other cumbersome constructions like you see on different OE pistons.
5. One solid piece construction - Unlike OE's 2pc which the top (yellow) part is usually of "phenolic" - different material than aluminum so it can get cracked or separated due to the heat stress.
Regardless what type of OE caliper pistons you have:
Like this shaft/seal inside pistons from 996 Turbo
Or this type from 997 TT
Or this type from 997 GT2/3 (Phenolic top is separated from piston body):
They can be replaced with RB SS piston, seal and dust boot for a clean and less cumbersome set up, and bring your calipers to a new life.
Picture below shows SS pistons, Oil seal (in black), and Dust boots (blue) which is made of Teflon for high temperature track application. If you don't track you will only need standard (black) boots.

Site looks nice overall.
No love for 944 Turbos on the site. They have a dust seal vs a dust scraper and are nearly impossible to find. I have about given up rebuilding them. May be switching to a Wilwood caliper.
