On request, we can equip any
Panamera model in the range with
a braking system that has already
had to cope with the harshest
requirements of the racetrack: the
Porsche Ceramic Composite
Brake (PCCB). For the Panamera
and Panamera S models, it is
available only in conjunction with
19-inch wheels or larger and for
the Panamera Turbo, it is com-
patible only with 20-inch wheels.
On the Panamera and
Panamera S models, the cross-
drilled ceramic brake discs have
a diameter of 390 mm at the
front and 350 mm at the rear. To
cope with more powerful brak-
ing on the Panamera Turbo,
these discs are 410 mm at the
front and 350 mm at the rear.
PCCB is characterised by its low
thermal expansion, which pre-
vents deformation under heavy
braking. Furthermore, the
ceramic brake discs are totally
resistant to corrosion and offer
more favourable noise-damping
properties.
The use of six-piston aluminium
monobloc brake calipers on the
front axle and four-piston units at
the rear – all finished in yellow
– ensures extremely high brake
forces which, crucially, are excep-
tionally consistent. The pedal
response is fast and precise with
only moderate input required.
All the necessary ingredients are
there for a short braking distance,
even in the toughest conditions.
Moreover, safety under braking at
high speeds is increased thanks
to the excellent fade resistance of
PCCB.
The key advantage of PCCB is
the extremely low weight of the
ceramic brake discs, which are
approximately 50 % lighter than
standard discs of similar design
and size. As well as enhancing
performance and fuel economy,
this represents a major reduction
in unsprung and rotating masses.
The consequence of this is better
road holding and increased com-
fort, particularly on uneven roads,
as well as greater agility and
improved handling.
Please note that circuit racing,
track day use and other forms of
performance driving can signifi-
cantly 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.
