Product Details and Specifications

The DuraGo BR900478-01 rotor is made from cast iron, a material known for its excellent thermal conductivity and wear resistance, making it suitable for heavy-duty braking applications. Its vented construction allows air to flow between the rotor surfaces, helping to dissipate heat more effectively and reduce brake fade during prolonged use. The rotor features a rust resistant coating that helps protect against corrosion, which is especially beneficial in wet or humid environments.

This rotor is designed as a drum-in-hat type, integrating a parking brake drum within the rotor assembly, which is common in many Audi Q7, Porsche Cayenne, and Volkswagen Touareg models. The 5 mounting bolt holes with a bolt circle diameter of 130 mm (5.12 inches) ensure a secure and precise fit. The non-directional brake surface allows for flexible installation without concern for rotor orientation.

Compatible Vehicles and Applications

• Compatible with Audi Q7 models requiring a 12.98-inch vented disc brake rotor
• Fits Porsche Cayenne vehicles with drum-in-hat rear brake systems
• Suitable for Volkswagen Touareg models with matching rotor specifications
• Ideal replacement for worn or damaged rear disc brake rotors on these vehicles
• Designed to maintain proper braking performance and safety standards

Installation Notes and Tips

• Ensure rotor surface is clean and free of oil or debris before installation
• Check brake pads for wear and replace if necessary to ensure optimal braking
• Torque mounting bolts to manufacturer specifications to avoid rotor warping
• Verify rotor thickness before installation; replace if below discard thickness of 1.02 inches (26 mm)
• Use proper tools and follow vehicle-specific service manual instructions
