Porsche Surface Coated Brakes have a thin layer of tungsten carbide on the outside of the rotor. This tungsten carbide layer means no rust, significantly less brake dust, and they don't have brake fade typical of cast-iron brake rotors.
The tungsten carbide layer is applied using high velocity oxygen fuel spray, and provides a rotor that lasts about 30% longer than traditional iron rotors. Better performance comes at a price, but they're about 1/3 the cost of carbon ceramic rotors.
These PSCB rotors come standard on the Porsche Cayenne Turbo and Cayenne Coupe Turbo. Check out the video to learn all about Porsche's world-first brakes!
