brake technology that has already
had to withstand the harshest
requirements of motorsport: the
Porsche Ceramic Composite
Brake (PCCB).
To enhance braking performance,
the ceramic composite brake
discs in PCCB have a diameter
of 380 mm at the front and
350 mm at the back. They are
made from a specially treated
The use of six-piston aluminium
monobloc brake calipers at the
front and four-piston units at the
rear ensures extremely high
brake forces which, crucially, are
exceptionally consistent. The pedal
response is fast and precise
with only moderate input required.
All the prerequisites are there for
a short braking distance, even in
the toughest conditions. Moreover,
safety when braking from high
speeds is increased thanks to
PCCB’s excellent fade resistance.
carbon-fibre compound that is
silicated in a high-vacuum process
at around 1,700 °C. The resulting
brake discs are much harder
and more resistant to heat than
standard discs.
PCCB is characterised by its low
thermal expansion which prevents
deformation under heavy braking.
Furthermore, the ceramic brake
discs are totally resistant to
corrosion and offer better noise-
damping properties.
The key advantage of PCCB is the
extremely low weight of the brake
discs which are about 50 % lighter
than standard discs of similar
design and size. In addition, the
monobloc calipers for the new
911 GT3 on the front and rear axle
are made from aluminium, saving
around 4.8 kg per vehicle com-
pared to standard calipers. These
factors not only have an impact
on performance and fuel consump-
tion, but also reduce unsprung and
rotating masses.
The result: better road-holding
and increased comfort, especially
on uneven roads, as well as
greater agility and even better
handling.
Please note that circuit racing
or other forms of performance
driving can significantly reduce
the service life of even the most
durable brake pads and discs.
As with conventional high-
performance braking systems,
we recommend that all brake
components be professionally
inspected and replaced where
necessary after every track event.
