General Information
The following applies when using the Carbon-Ceramic Brake Wear Tester : VAS6813 to determine wear:
This is a new test procedure to determine the wear limit of the ceramic brake rotors.
The wear indicators on the brake rotor are no longer present.
The brake rotor must not be weighed again.
Refer to CERAMIC BRAKE ROTOR WEAR, GENERAL INFORMATION
The brake rotor can be identified by the following points:
- The wear indicators -arrow- on the friction surface of the brake rotor are no longer present
- At the printed marks -A through D-
The check occurs by determining the brake rotor thickness "and" the wear value with the Carbon-Ceramic Brake Wear Tester: VAS6813 , both must be measured three times respectively around the circumference.
On the brake rotor cup the permitted minimum thickness "min.th" of the brake rotor is engraved.
On the brake rotor cup the wear value -C- of the brake rotor for the Carbon-Ceramic Brake Wear Tester: VAS6813 is engraved.
Value -A- is a value from the production of the new brake rotor
The values -A and C- can be different depending on the location.
The values -A and C- can be different depending on the brake rotor.
Example of minimum thickness: -3-, brake rotor thickness. It must not fall short of this value.
The value -3- can be different depending on the brake rotor.
