General Information On Replacing Worn PCCB Brake Discs
Three criteria governing the condition of the parts can make replacement necessary depending on the wear of PCCB brake discs:
- Surface changes in the brake disc friction surfaces (material fatigue/wear) at an advanced stage (indication of wear: associated friction surface damage > 1 cm2 ).
- Surface roughness of the brake disc friction surfaces too great (roughness depends on mileage and load).
- Brake disc minimum thickness is not attained due to wear (material erosion due to friction).
- In practice, all three forms of brake disc erosion usually occur.
- Only in rare cases (in the case of long-term race driving brake loads/very high temperatures on the friction surfaces) does the surface change so quickly that a premature brake disc change has to be performed.
- Blue discs on the brake disc chamber and/or strongly colored brake calipers indicate a long-term, sustained high load, on a racing circuit, for example.
