Coating On The PCCB Brake Discs (Potential Causes)

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.
• Perforation bores -see Figure- in the brake discs must not be blocked. Clear them if necessary → Checking Information On PCCB Brake Discs  .
• In the event of brake pad wear, the brake discs can still be used provided the brake discs satisfy all wear criteria → Checking Information On PCCB Brake Discs  .
