Visual Inspection Of The Surfaces Of The Brake Disc Friction Surfaces (Indication Of Wear)

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.

Information

The friction surface changes occur due to material fatigue as a result of extremely high thermal load. These disc temperatures, which occur above all in racing conditions, cause a progressive material fatigue.
Effects on driving: The surface change worsens the smoothness of braking, decreases the disc strength and increases the brake pad wear and therefore makes a precautionary parts replacement necessary.

The following illustrations (PCCB brake disc wear appearance) are to be used for damage assessment.
