Porsche Ceramic Composite Brake (PCCB).
As an optional alternative, the
Cayenne S, Cayenne GTS and
Cayenne Turbo can all be
equipped with the race-proven
Porsche Ceramic Composite
Brake (PCCB)*.
The large disc diameter (410 mm
front and 370 mm rear) adds
significantly to brake performance.
The discs are made from a
specially treated carbon-fibre
compound that is silicated in a
high-vacuum process at 1,700 ºC.
The resulting material is not only
much harder than cast iron, it
is also more resistant to heat.
Even at high temperatures, the
thermal resistance of the PCCB
disc ensures excellent dimensional
stability. The ceramic material is
totally resistant to corrosion and The pads are mounted in six-
