Front Brakes
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2015 Audi S7, 2015 Audi RS 7, 2015 Audi A7 Quattro, 2014 Audi S7, and 2014 Audi RS 7. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Hairline cracks on brake rotor friction surfaces are often observed during brake repairs. Hairline cracks up to 10 mm long are not a technical flaw and are not cause for brake rotor replacement.
Brake rotors with friction surfaces that have worn through should be replaced.

NOTE:
The minimum brake rotor weight may be stamped on, depending on the version. The brake rotor must be weighed for additional wear evaluation. If the minimum weight has been reached, the brake rotor must be replaced. Always replace brake rotors in pairs on each axle.
NOTE:
Hairline cracks on the friction surface on ceramic brakes occur during the manufacturing process and can be found on new brakes in different stampings. Hairline cracks on the friction surfaces are not a reason to exchange the ceramic brake rotors.
NOTE:
The brake system installed in a vehicle is documented on the vehicle data sticker via the relevant PR number -A and B-.
