On request, we can equip your
Cayman S with a brake system
that has already had to cope
with the harshest requirements of
motorsport: the Porsche Ceramic
Composite Brake (PCCB). The
ceramic brake discs have a diam -
eter of 350 mm front and rear –
for extremely powerful braking. All the necessary ingredients are
there for a short braking distance,
even in the toughest conditions.
Moreover, safet y under braking

at high speeds is increased thanks
to the excellent fade resistance
of PCCB.
The key advantage of PCCB is that
the brake discs are approximately
50 % lighter than standard discs
of similar design and size. A factor
The brake discs are formed from

a specially treated carbon -fibre
compound that is silicated in a
high-vacuum process at approxi -
mately 1,700 °C. Not only are the
resulting discs much harder than
standard discs, they are more
resistant to heat. The low thermal
expansion of the brake discs
prevents deformation under heav y
braking. Furthermore, the ceramic
brake discs are totally resistant to that helps to reduce unsprung and
rotating masses on the vehicle.
The consequence of this is bet ter
road holding and increased

comfort, particularly on uneven
roads, as well as greater agilit y
and improved handling.
Please note that circuit racing,
trackday use and other forms
of performance driving can
significantly reduce the service life

it is automatically reactivated for
your safet y if either of the front
wheels (in ‘Sport ’ mode, both
of the front wheels) requires ABS
assistance. ABD remains perma -
nently active. Two additional
functions of PSM increase safet y
even further: precharging of the
brake system, and brake assist.
If you suddenly release the accel -
erator pedal, PSM automatically
readies the braking system. With
the braking system having been
precharged, the brake pads are
already in light contact with the
brake discs. Maximum braking
power is therefore achieved much rigidit y of the car. The forces

(PSM).
PSM, which comes as standard, is
an automatic control system that
stabilises the vehicle at the limits
of dynamic driving performance.
Sensors continuously monitor
driving direction, speed, yaw veloc-
it y and lateral acceleration. Using
this information, PSM computes the
actual direction of motion. If this
direction deviates from the desired
course, PSM initiates braking
interventions targeted at individual
wheels in order to stabilise the
vehicle.
sooner. When sudden braking is
detected, the brake assist function
applies maximum brake pressure
to all four wheels.

transverse members at the front

improves traction using the ABD
(automatic brake differential)
and ASR (anti-slip regulation)
functions, giving an agile
response. When ‘Sport ’ mode is
selected on the optional Sport
Chrono Packages (p. 62), the PSM
intervention threshold is raised to
enable greater driver involvement
– particularly at speeds of up to
approximately 70 km/ h (45 mph).
The integrated ABS can further
reduce the braking distance.
For an even sportier drive, PSM
