Technical Details and Specifications

The DuraGo BR900474 rotor is designed with a nominal thickness of 1.34 inches (34 mm) and a discard thickness of 1.26 inches (32 mm), ensuring a precise fit and long service life. Its overall height measures 2.7 inches (68.5 mm), and the center hole diameter is 3.35 inches (85 mm), matching factory dimensions for seamless replacement. The rotor features a vented design to enhance cooling during braking, reducing the risk of brake fade under heavy use. This rotor does not include an ABS tone ring and is not cross-drilled or slotted, maintaining a conventional braking surface suitable for daily driving and moderate performance needs.

Compatible Vehicles and Applications

This disc brake rotor is compatible with the following vehicles:

• Audi Q7
• Porsche Cayenne
• Volkswagen Touareg

It is designed to meet the OEM specifications for these models, providing a direct replacement option for worn or damaged rotors.

Common Issues Addressed by This Rotor

• Brake rotor warping causing vibration during braking
• Excessive rotor wear leading to reduced braking efficiency
• Overheating and brake fade under heavy load conditions
• Uneven rotor surface causing noise or pulsation
• Corrosion-related rotor degradation (note: this rotor does not have rust-resistant coating)

Installation Notes and Tips

When installing the DuraGo BR900474 rotor, ensure the mounting surface is clean and free of debris. Verify the rotor thickness before installation to confirm it meets or exceeds the discard thickness of 1.26 inches (32 mm). Use proper torque specifications for the 5 mounting bolts with a 5.12 inch (130 mm) bolt circle diameter. Since this rotor is non-directional, it can be installed on either side without concern for rotation direction. It is recommended to replace brake pads simultaneously to maintain optimal braking performance.
