General Repair Information

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2021 Audi S8, 2021 Audi A8 e Quattro, 2021 Audi A8 Quattro, 2020 Audi S8, and 2020 Audi A8 e Quattro. However, it is still accessible from the selected car via links, so may be relevant.

Hairline cracks on the brake rotor friction surface are often noticed during brake repairs. Hairline cracks up to 10 mm long are not a technical flaw and do not justify a brake rotor replacement.
Brake rotors and brake pads that have a worn through friction surface should be replaced.
