Coating On The PCCB Brake Discs (Potential Causes)
WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2012 Porsche Cayman, 2012 Porsche Boxster, 2011 Porsche Cayman, 2011 Porsche Boxster, and 2010 Porsche Cayman. However, it is still accessible from the selected car via links, so may be relevant.
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.
