The 911 Turbo and 911 Turbo S

Porsche Ceramic Composite
Brakes (PCCB).
The 911 Turbo S models are
equipped as standard with a
PCCB
braking system that has already
proved it can withstand even
the toughest racing conditions,
such as those encountered in
the Porsche Mobil 1 Supercup.
That system is the Porsche
Ceramic Composite Brakes
(PCCB). PCCB is available as an
option for 911 Turbo models.
The ceramic discs have a
diameter of 14.96 inches (380
mm) at the front and 13.78
inches (350 mm) at the rear.
The discs are made from a
specially treated carbon-fiber
compound that is silicated
in a high-vacuum process
at 3,000°F. The resulting
material is not only much
harder than metal—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
offers excellent acousticdamping
properties.
The pads are mounted in sixpiston,
aluminum monobloc
fixed calipers at the front, with
four-piston units at the rear. The
resulting brake forces are both
extremely high and remarkably
consistent. The pedal response
is fast and precise with only
moderate input required.

PCCB enables shorter braking
distances in even the toughest
road and race conditions.
Excellent fade resistance helps
to ensure greater balance
when the vehicle is slowing
from racetrack speeds.
