⇒ "3 Ceramic front brakes (PR 1LW)", page 54
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.
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.

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.
