The brake discs have wear indicator plates in the friction surfaces. The wear indicator plates (six on each brake disc) are arranged close to the outer diameter, offset by 120° at three points -arrows- . The three wear indicator plates on each friction surface (3 on the inside and 3 on the outside) are positioned directly opposite each other. Each wear indicator is approx. 2 cm2 . The wear indicators are barely visible on new brake discs.
The minimum brake disc thickness (wear dimension) is stamped on the brake disc hub (example: Min. Th. 37.7 mm).
