Please note that circuit racing,
track day use and 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
On request, we can equip the new
Panamera models with a braking
system that has already had to
cope with the harshest require-
ments of the racetrack: the
Porsche Ceramic Composite Brake
(PCCB). For the Panamera S mod-
els, it is available only in conjunc-
tion with 19-inch wheels or larger
and for the Panamera Turbo, it is
compatible only with the 20-inch
RS Spyder Design wheel.
Presumably, you won’t be using your Panamera for motorsport activities.
But you never know.

On the Panamera S and
Panamera 4S, 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 braking on
the Panamera Turbo, these discs
are 410 mm at the front and
350 mm at the rear. The brake
discs are formed from a specially
treated carbon-fibre compound
that is silicated in a high-vacuum
process at approximately
1,700 °C. Not only are the
resulting brake discs much
harder than standard discs,
they are more resistant to heat.
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
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
exceptionally 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 comfort, particularly
on uneven roads, as well as
