Coating On The Pccb Brake Discs (Possible Causes)
WARNING: This page is about a different variant/trim than selected.
The coating on the PCCB brake discs arises as a result of a high load and high temperatures, for example on a racing circuit. Check the following in such cases:
Bores (perforations) in brake disc friction surface
- Ventilation (brake cooling): All components are present, secured correctly and undamaged.
- Brake pad quality: If the vehicle is used for race-track driving, use appropriate brake pads.
- The perforation bores
> Bores (perforations) in brake disc friction surface
in the brake discs must not be blocked. Unblock them if necessary.
