World premiere of the Porsche Surface Coated Brake
In the new Cayenne, Porsche is launching an innovative new braking technology: the Porsche Surface Coated Brake (PSCB). At the core of this new technology are discs with an exceptionally hard tungsten-carbide coating, combined with specially developed brake pads. Compared to conventional grey cast iron brakes, the new system boasts far superior properties - including an up to 30 per cent longer service life. The discs not only wear at a significantly slower rate, but also generate less brake dust accumulation on the rims. The increased friction values of the brakes also ensure improved responsiveness. The PSCB delivers stable braking even under extreme stress. As with the Porsche Ceramic Composite Brake (PCCB), which is still available as an option, the PSCB uses ten-piston callipers at the front and four-piston callipers at the rear.
A side effect of the new technology is the unique appearance of the coated discs. After around 600 kilometres of day-to-day driving, the pads will have polished the surface to a gleaming shine, creating a mirror-like finish. The aesthetic effect is enhanced by the white brake callipers. The PSCB is included as standard on the Porsche Cayenne Turbo, and is available as an option for all other Cayenne models. The PSCB is available in combination with 20 or 21-inch wheels.
