ATE is a Continental Automotive Systems brand with deep original equipment brake system experience, and that background is reflected in the rotor’s material selection, coating, and dimensional accuracy. This rotor is specified for rear brake service on 2002-2006 Audi A4 and 2002-2006 Audi A4 Quattro models with a 255 mm rear rotor application. This part cross-references Bosch 14010021 for the same application.

What It Helps Address

• Rear brake vibration caused by worn or uneven rotor surfaces
• Corrosion on exposed rotor surfaces
• Brake pulsation from rotor thickness variation
• Reduced braking consistency from worn rear rotors
• Service replacement needs for 2002-2006 Audi A4 and Audi A4 Quattro rear brakes

Installation Notes and Tips

Verify rotor diameter, thickness, and rear fitment before installation. Confirm the vehicle is a 2002-2006 Audi A4 or Audi A4 Quattro with the specified 255 mm rear rotor setup. Clean the hub mounting surface before installing the rotor, and inspect pads, caliper hardware, and wheel bearings for wear that could affect braking feel. Follow the vehicle manufacturer’s service procedures and torque specifications during brake service.

Quality Assurance

ATE brake parts are engineered to a higher standard than conventional replacement parts, using experience gained from original equipment brake system development. The coated rotor design supports corrosion resistance and consistent service quality for Audi A4 rear brake maintenance.
