Problem Description In certain vehicles, the brake master cylinder casting may be too short. If the brake master cylinder casting is too short, the driver may experience a sudden loss of hydraulic brake performance, with the brake pedal possibly going down to the floor. This can lead to a crash without warning.

The electronic parking brake and its emergency brake function are not affected and will still function.

Corrective Action Inspect and, if necessary, replace the brake master cylinder.

The expected replacement rate for the brake master cylinder is estimated to be very low (less than 1%). Audi expects to find only five (5) vehicles worldwide in the whole affected volume that will require a replacement part.
