The 2019 Cayenne will be the first Porsche vehicle to feature Porsche Surface Coated Brakes (PSCBs). The discs are covered with extremely hard tungsten-carbide and are 30% more resistant than steel discs. Obviously, the callipers (ten-piston front and four-piston rear) have been adjusted accordingly ($$$$ and maybe $$$$$). White in colour, these callipers were purposely chosen by Porsche because PSCBs emit virtually no dust. Ceramic brakes will still be available on option.
