the resulting braking discs much
harder than standard discs, they
are more resistant to heat.
PCCB is characterised by its low
thermal expansion, which prevents
deformation under heavy braking.
Furthermore, the ceramic brake
discs are totally resistant to
corrosion and offer more favour-
able noise-damping properties.

Please note that circuit racing,
trackday use and other forms
of performance driving can
significantly reduce the service
life of even the most durable
brake 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.
