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: use the appropriate brake pads if the vehicle is being used on a racing circuit.
- Perforated bores -see illustration- in the brake discs must be free. Expose them if necessary → Note Concerning Bores (Perforations) In The Brake Disc Friction Surface .
- The brake discs can still be used even if there is a coating on them provided that they are OK with respect to all wear criteria → General Information On Replacing Worn PCCB Brake Discs . The perforated bores -see illustration- must be free.
