Brake discs
Note
When performing repair work on brakes, hairline cracks are
♦
often found on the friction surface of the brake discs. Hairline
cracks up to a length of 10 mm do not present a technical
problem and do not justify a renewal of brake discs.
Brake discs with cracks going all the way across the friction
♦
surface must be renewed.

Note
Hairline cracks on the friction surfaces of ceramic brakes can be
caused during manufacturing and therefore already appear to
varying degrees when the brakes are new. Hairline cracks on the
friction surfaces do not justify a renewal of the ceramic brake
discs.
