For the 2019 Porsche Cayenne, Porsche launched a new rotor and pad combination that comes with a white brake caliper. The Porsche Surface Coated Brake (PSCB) has a hardened tungsten carbide coating and specially developed brake pads to improve performance and reduce brake dust. Compared to conventional cast iron brakes, the rotors generate up to 90% less brake dust.
The PSCB brake package is a $3,500 option. It uses ten-piston calipers at the front and four-piston calipers in back. A side effect of the new technology is the unique appearance of the coated discs. After an initial period of day-to-day driving, the pads polish the surface, creating a mirror-like finish. The only drawback is replacement rotors from Porsche – the tungsten carbide-coated units are only sold in pairs and can cost more than $3,000 for just the front rotors.
