Checking information on PCCB brake discs
Basic information
Checking involves the following:
1. Visual inspection for any surface changes to the brake disc friction surfaces Indication of wear: Associated surface fracture > 1 cm2 -arrow-, but
no accumulation of smaller fractures.
2. Assess the surface roughness (Sr) of the brake discs (max. 80 microns permitted), since this affects smoothness of braking (noise), braking
performance/pedal pressure and brake pad idle time.
3. Check brake discs for minimum thickness -x-. The minimum thickness of the brake disc (example: Min. Th. 33.7 mm) is stamped on the brake
disc chamber.
4. Check brake discs for edge damage -see illustration- (damage caused as a result of improper use).
