Note
Depending on the version, the minimum weight of the brake disc
is stamped on the disc. The brake disc must then be additionally
weighed in order to assess the amount of wear. The disc must be
renewed when the minimum weight is reached. Brake discs
should always be renewed on both sides of the axle.

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.

The minimum thickness of the
