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

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.
