Ceramic Brake Rotor Wear, General Information

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2022 Audi S5 Sportback, 2022 Audi RS 5 Sportback, 2022 Audi A5 Sportback, 2021 Audi S5 Sportback, and 2021 Audi RS 5 Sportback. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

The wear is determined 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 brake rotor minimum thickness "min.th." and the wear value -C- are engraved on the brake rotor cup for the Carbon-Ceramic Brake Wear Tester:VAS6813 .

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.

NOTE:

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

CAUTION:

Risk of accident due to uneven braking.

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