Active safety: standard braking system.
Positive feature: negative acceleration.
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. Perfect for the 911.
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,
black anodised four-piston alu-
minium monobloc fixed calipers
are used on the front and rear
axles. The closed-type design of
these brake calipers makes them
particularly stiff. The front and
rear brake discs have a diameter
of 330 mm for outstanding
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.
