Information
- Irrespective of wear, a brake disc change can be necessary on the brake disc friction surfaces due to edge damage.
- In such cases, only one brake disc may need to be replaced if the friction area surface of the other PCCB brake disc is still completely OK.
The following criteria apply to edge damage assessment:
- Max. permissible width/depth = 2 mm
- Max. permissible length = 10 mm
- Max. 3 damaged edge areas permissible
