Porsche Ceramic Composite Brake (PCCB).
When it comes to brake technology, nothing holds us back.
On the 911 Turbo models, the
ceramic discs have a diameter of
380 mm at the front and 350 mm
at the rear. 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 metal,
it is also more resistant to heat.
Even at high temperatures, the
