Ceramic Brake Rotor Wear, General Information

WARNING: This page is about a different car, the 2022 Audi SQ7, 2022 Audi S7, and 2022 Audi Q7. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

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.

The permitted minimum thickness of the brake rotor with "min.th" as well as the wear limit -C- for the Carbon-Ceramic Brake Wear Tester: VAS6813 are engraved on the brake rotor cup.

The wear value -C- is different depending on the brake rotor and the measurement location.

NOTE:

If the brake rotor thickness "min.th." falls short at one measuring point, the brake rotor must be replaced.

"or"

if one of the three wear values -C- is reached or falls short when determining the wear using the Carbon-Ceramic Brake Wear Tester: VAS6813 , the brake rotor must be replaced.

The wear value -C- is different depending on the brake rotor.

WARNING:

Risk of accident due to insufficient braking effect.

Ceramic brakes should be replaced when, one of the defined wear limits is reached. The brake rotor can no longer be driven.

If a brake rotor is damaged or worn, check the other brake rotors for damage and wear.
