For brake disks and brake pads, the break-in requirements specified by the vehicle manufacturer must be observed.

When replacing brakes, the chassis components must always be checked with regard to clearance and the wheel hub with regard to wobble, and the appropriate documentation must be produced.

If the vehicle is no longer in its original condition due to tuning work such as wheel accessories and tracking plates, the entitlement to make warranty claims is lost due to third-party work. The same warranty claims are lost if the vehicle is used for motor sports or similar events.
