Causes Of Build-Up On PCCB Brake Discs
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:
- 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 in the brake discs must not be blocked. Unblock them if necessary. > Bores (perforations) in brake disc friction surface
NOTE:
Work cannot be carried out on the bores in the brake disc friction surface
- Damage to brake discs
→ Clean the bores on PCCB brake discs with high-pressure cleaning equipment if necessary. Observe the relevant environmental and safety regulations.
→ Do not machine the bores. Drilling or counter-sinking is not permitted.

If there is a build-up, the brake discs can still be used provided all wear criteria for the brake discs are OK.
