Porsche brakes are renowned
for their stopping power, setting
the standards for deceleration
and stability. They are designed
to cope with extreme forces
such as those experienced during
hard braking.
The brake calipers have a mono-
bloc aluminium construction.
This makes them tough but light
and enables a rapid response
and release of the brake. The
pedal travel is short and easy to
modulate.
In models with the 3.6-litre engine,
a new generation of braking
system with black anodised four-
piston aluminium monobloc fixed
calipers is used on the front and
rear axles. The brake calipers are
now even stiffer thanks to their
Active safety: standard braking system.
Positive feature: negative acceleration.

closed-type design. The brake disc
diameters are larger: 330 mm
front and rear and the rear brake
discs are 4 mm thicker – for even
better braking performance.
The S models have four-piston
aluminium monobloc calipers
that are larger, reinforced and
have a striking red painted finish.
The front axle has larger brake
pads and thicker brake discs.
All models have cross-drilled
brake discs ensuring optimum
braking in the wet. The discs are
internally vented for rapid heat
dispersal.
Other features include a
powerful 10-inch brake booster
for reducing pedal effort in the
rear-drive models and integral
air spoilers for enhanced air flow
in the brake cooling ducts.
For even better braking perform-
ance with braking force support,
a 9-inch tandem brake force
amplifier is used on the all-wheel
drive models.
