Tech Report Porsche 944 Turbo
The Porsche 944 turbo calipers are one of the most advanced designs on the road today. It has a 4-piston design that delivers a considerable amount of brake force to each rotor. The caliper pictured here is from on a street-legal racecar. The lightweight alloy construction maximizes heat dispersion and replaces the heavier cast iron two piston caliper.
The caliper you see pictured above was sent to us with multiple layers of different colored “do-it-yourself” powder coatings. The first thing we had to do was remove the layers of coating and get the calipers down to bare alloy. Once this was done we preheated the casting and applied our Polymer caliper coating. Once applied, the Polymer coating was thermally cured to blend the molecules into one tough layer of protection encapsulating the entire casting. This coating is very durable but so thin that it does not interfere with the movement or fit of the brake pads or hardware. The final step in the rebuilding process was to re-assemble with new hydraulics and bleeder screws.
Our Polymer coating is far superior to Powder coating or brush applied coatings which tend to be so thick that they trap heat inside the caliper. Excess thickness can also result in having to scrape off where the pads and hardware are installed in order to have adequate space. Our Polymer coating is so thin (.005 inches) that it can be applied in areas such as inlets and bleeder screw holes and thus reduce the chance of unsightly rust deposits.
As you can see in the above picture, the rebuilt caliper is back to a near new condition. If you are concerned about the type of aftermarket “powder coating” on your vehicle or have other brake questions, please give us a call.
