This Technical Service Bulletin addresses brake rotor vibration or pulsation concerns in certain Volkswagen vehicles. The bulletin provides information on service procedures, including brake rotor inspection, machining, and replacement.
Symptoms: Brake pedal pulsation, vibration felt in the vehicle body, and steering wheel shakes when applying the brakes at highway speeds.
Service Procedure:
A detailed brake rotor inspection is necessary to determine if the brake rotor should be machined or replaced. The inspection should check for severe discoloration, high heat surface damage, or visible cracks on the brake rotor friction surfaces.
Notes:
Brake rotors showing these conditions are not serviceable and must be replaced according to the Volkswagen Warranty Policy and Procedure Manual. Properly machined brake rotors may reduce brake pulsation/vibration after several months in service.
