Detailed Product Description

The DuraGo BR900684 disc brake rotor is specifically designed for Audi A6 and A6 Quattro vehicles, ensuring compatibility and optimal braking performance. Constructed from cast iron, this rotor offers effective heat dissipation to minimize brake fade during extended use. Its vented, full cast design enhances airflow, helping to maintain cooler operating temperatures. The rotor features a drum-in-hat configuration, integrating a parking brake drum within the rotor hat, which is common for these Audi models. With a non-directional brake surface, installation flexibility is improved, allowing the rotor to be mounted in either orientation without affecting performance. The precise dimensions, including a 12.99-inch outside diameter and 5 mounting bolt holes, ensure a secure and exact fit for the specified vehicles.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Addressing reduced braking efficiency due to rotor thickness below discard limits
• Resolving noise issues related to uneven rotor surfaces
• Upgrading to a vented rotor for improved heat management
• Ensuring proper fitment for Audi A6 and A6 Quattro brake systems

Installation Notes and Tips

• Verify rotor thickness before installation; replace if below 0.79 inches (20 mm)
• Ensure mounting surfaces are clean and free of debris for proper rotor seating
• Torque mounting bolts to manufacturer specifications to avoid rotor warping
• Check compatibility with existing brake pads and hardware
• Perform a brake system inspection after installation to confirm proper operation
