Detailed Product Description

The DuraGo BR900478 disc brake rotor is constructed from full cast iron, providing a robust and heat-resistant braking surface. Its vented design allows air to flow between the rotor faces, helping to dissipate heat generated during braking and reducing the risk of brake fade under heavy use. This rotor features a drum-in-hat design, integrating a parking brake drum within the rotor hat, which is compatible with the parking brake system on select Audi Q7, Porsche Cayenne, and Volkswagen Touareg vehicles.

With a non-directional brake surface, the rotor can be installed on either side of the vehicle without concern for directional rotation. The rotor measures 329.7 mm in outside diameter and 73.7 mm in overall height, ensuring proper fitment and clearance. The mounting bolt pattern includes five holes spaced on a 130 mm bolt circle diameter, matching OEM specifications for the listed vehicle models.

Compatible Vehicles and Applications

• Designed for Audi Q7 models requiring a 329.7 mm vented disc rotor
• Compatible with Porsche Cayenne vehicles equipped with drum-in-hat parking brake rotors
