Porsche Ceramic Composite
Brake (PCCB).
On request, we can equip your
Cayman S with a brake system
that has already had to cope
with the harshest requirements of
motorsport: the Porsche Ceramic
Composite Brake (PCCB). The
ceramic brake discs have a diam-
eter of 350 mm front and rear –
for extremely powerful braking.

The brake discs are formed from
a specially treated carbon-fibre
compound that is silicated in a
high-vacuum process at approxi-
mately 1,700 °C. Not only are the
resulting discs much harder than
standard discs, they are more
resistant to heat. The low thermal
expansion of the brake discs
prevents deformation under heavy
braking. Furthermore, the ceramic
brake discs are totally resistant to
corrosion and offer more favour-
able noise-damping properties.
Six-piston aluminium monobloc
fixed calipers on the front axle
and four-piston units at the
rear provide a high and constant
brake pressure. The pedal
response is fast and precise with
only moderate input required.
