Detailed Product Description
The DuraGo BR900678 is a vented disc brake rotor constructed from full cast iron, providing a balance of strength and heat dissipation essential for maintaining braking efficiency. Its vented design helps reduce heat buildup during braking, which is critical for preventing brake fade on Audi A6 and A6 Quattro vehicles. The rotor measures 12.63 inches in outside diameter and features a nominal thickness of 1.18 inches, ensuring compatibility with factory specifications. With five mounting bolt holes arranged on a 4.41-inch bolt circle diameter, this rotor fits securely and aligns precisely with the vehicle’s hub. The non-directional brake surface allows for flexible installation without concern for rotor orientation.
Compatible Vehicles and Applications
This disc brake rotor is specifically compatible with Audi A6 and A6 Quattro models, designed to meet the OEM fitment and performance standards. It is suitable for drivers seeking a direct replacement rotor that maintains the original braking characteristics of their vehicle.
- Addresses brake rotor wear and thickness below discard limits
- Resolves issues related to brake vibration and noise
- Improves heat dissipation to reduce brake fade
- Restores braking performance after rotor damage or warping
Installation Notes and Tips
When installing the DuraGo BR900678 rotor, ensure the mounting surface is clean and free of rust or debris to promote proper fitment. Use the correct torque specifications for the five mounting bolts to avoid rotor distortion. Since this rotor does not include an ABS tone ring, verify ABS sensor compatibility if applicable. It is recommended to replace brake pads simultaneously to optimize braking performance and rotor longevity.
