a highvacuum process at
1,700 °C. The resulting material
is not only much harder than
metal, it is also more resistant
to heat.
Even at high temperatures, the
thermal resistance of the PCCB
discs ensures excellent dimen
sional stabilit y. The ceramic
material is totally resistant to
corrosion and of fers excellent
acoustic damping properties.
The pads are mounted in six
piston monobloc aluminium
fixed calipers at the front, with
Porsche Ceramic Composite
Brake (PCCB).
Motorsport is the ultimate test
of braking performance. On
request, we can provide you
with a brake system that has
already had to cope with the
harshest requirements of motor
racing – a brake system fit ted
in the cars competing in the
Porsche Mobil 1 Supercup, for
example: the Porsche Ceramic
Composite Brake (PCCB).
The ceramic discs have a dia
meter of 350 mm front and
rear. The discs are made from
a specially treated carbon fibre
compound that is silicated in four
piston units at the rear. The
resulting brake forces are both
extremely high and remarkably
consistent. The pedal response
is fast and precise with only
moderate input required.
PCCB enables shorter braking
distances in even the toughest
road and race conditions. Excel
lent fade resistance ensures
greater balance when slowing
from racetrack speeds.
The key advantage of PCCB is
the total weight saving of
approximately 50 % over metal discs with similar construction
and dimensions. As well as
enhancing per formance and
fuel economy, this represents
a major reduction in both the
unsprung and rotating masses.
This, of course, offers major
benefits in terms of comfort
and road holding on uneven
road surfaces as well as general
handling and agilit y.
Please note that circuit racing,
trackday use and other forms
of per formance driving can
significantly reduce the service
life of even the most durable pads and discs. As with conven
tional high per formance braking
systems, we recommend that
all brake components be profes
sionally inspected and replaced
where necessary after every
track event.
