When it comes to brake technology, we demand nothing but the best.

only much harder than metal, it
is also more resistant to heat.
Even at high temperatures, the

PCCB enables shorter braking
distances in even the toughest

lent fade resistance ensures
greater balance when slowing
from racetrack speeds.
The key advantage of PCCB is
the total weight saving of approxi-
mately 50 % over comparable
metal discs. The mounting bells
on both front discs are made
from weight-saving aluminium. As
well as enhancing performance
and fuel economy, there is a major
reduction in both the unsprung
and rotating masses. This, of
course, improves comfort and
road-holding on uneven road
corrosion and offers excellent surfaces as well as general
acoustic damping properties. handling and agility.
The pads are mounted in six-piston
monobloc aluminium fixed calipers
at the front, with four-piston units
at the rear. The resulting brake
forces are not only extremely
high, they are also exceptionally
consistent. The pedal response
is fast and precise with only
moderate input required.

Please note that circuit racing,
trackday use and other forms of
performance driving can signifi-
cantly reduce the service life of
even the most durable pads and
discs. As with conventional high-
performance braking systems,
we recommend that all brake
components be professionally
inspected and replaced where
necessary after every track event.
