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

WARNING: This page is about a different car, the 2014 Porsche Cayenne, 2013 Porsche Cayenne, 2012 Porsche Cayenne, and 2011 Porsche Cayenne. 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.
