Technical Details and Compatibility

The DuraGo BR901398-01 rotor features a full cast iron construction that balances durability with effective heat management. Its vented design allows air to circulate between the rotor surfaces, helping to maintain optimal braking temperatures and reduce the risk of warping. The rotor’s rust-resistant coating helps prevent corrosion, which is especially beneficial for vehicles exposed to moisture and road salt.

This rotor is compatible with a variety of Audi models including the A4, A4 allroad, A4 Quattro, A5 Quattro, A5 Sportback, A6, A6 allroad, A6 Quattro, A7, A7 Quattro, A7 Sportback, A8 Quattro, Q5, Q5 PHEV, Q5 Sportback, S4, S5, S5 Sportback, SQ5, and SQ5 Sportback. The precise fitment ensures proper alignment and secure mounting with its 5-bolt pattern and 68 mm center hole diameter.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing rotor corrosion and surface rust that affects braking efficiency
• Improving brake cooling to reduce fade during extended or heavy braking
• Restoring proper rotor thickness to maintain safe braking performance
• Ensuring compatibility with ABS systems where tone rings are not required

Installation Notes and Tips

When installing the DuraGo BR901398-01 rotor, ensure the rotor surface is clean and free of any protective coatings or debris before mounting. Verify the rotor thickness is within the nominal range of 0.87 inches (22 mm) and replace if below the discard thickness of 0.79 inches (20 mm). Use proper torque specifications for the 5 mounting bolts to avoid rotor distortion. This rotor is non-directional, allowing installation on either side of the vehicle without concern for rotation direction.
