Porsche Ceramic Composite Brake
(PCCB).
The optional Porsche Ceramic Composite
Brake (PCCB) has a proven track record
from the world of motorsport. The cross-
drilled ceramic brake discs have a diame-
ter of 350 mm front and rear for even
more formidable braking performance.
The use of six-piston aluminium monobloc
brake calipers on the front axle and
four-piston aluminium monobloc brake
calipers at the rear – all finished in
yellow – ensures extremely high brake
forces which, crucially, are exceptionally
consistent. PCCB enables shorter braking
distances in even the toughest road and
race conditions.
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.
Circuit racing will require extra main-
tenance to be carried out in addition to
the routine maintenance.
Electric parking brake.
The electric parking brake, which you
can activate and deactivate manually,
releases automatically as you pull away.
With the hill-hold function, you can pull
away without ever rolling back. The
system automatically detects when the
vehicle has come to a halt on an uphill
gradient requiring intervention. PSM then
maintains the brake pressure at all four
wheels to prevent the vehicle from
moving in the opposite direction.
Airbags.
The new 911 Targa 4 models offer
advanced airbag technology in the form
of full-size driver and front passenger
airbags, which are inflated in two stages,
depending on the severity and type of
accident (e. g. frontal or offset frontal). In
less serious accidents, the airbags are
only partially inflated, thereby minimising
discomfort to the occupants.
Porsche Side Impact Protection System
(POSIP).
The new 911 Targa 4 models are equipped
as standard with the Porsche Side Impact
Protection System (POSIP). It comprises
side impact protection elements in the
doors and two airbags on each side. An
integral thorax airbag is located in each
seat side bolster, while the door panels
each contain an upwards-inflating head
airbag. Each thorax airbag has a volume
of 10 litres and each head airbag 15 litres,
ensuring excellent protection in the event
of a side impact.
Roll-over protection.
The 911 Targa 4 models have exemplary
torsional rigidity and flexural strength.
Increased protection is provided by the
steel roll-over protection system located
under the aluminium panel of the Targa
roll bar.
