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.\u003c\/p\u003e\u003cp\u003eWith 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.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDesigned for Audi Q7 models requiring a 329.7 mm vented disc rotor\u003c\/li\u003e\n\u003cli\u003eCompatible with Porsche Cayenne vehicles equipped with drum-in-hat parking brake rotors\u003c\/li\u003e\n\u003cli\u003eFits Volkswagen Touareg models with matching rotor specifications\u003c\/li\u003e\n\u003cli\u003eIdeal replacement for worn, warped, or damaged rotors on these vehicles\u003c\/li\u003e\n\u003cli\u003eAddresses issues such as brake noise, vibration, and reduced stopping power\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure rotor thickness is above discard thickness (26 mm) before installation\u003c\/li\u003e\n\u003cli\u003eClean mounting surfaces to prevent rotor runout and uneven wear\u003c\/li\u003e\n\u003cli\u003eTorque mounting bolts to manufacturer specifications for secure fitment\u003c\/li\u003e\n\u003cli\u003eCheck compatibility with existing brake pads and parking brake components\u003c\/li\u003e\n\u003cli\u003eInspect wheel bearings and hub assembly during rotor replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDuraGo manufactures the BR900478 rotor to meet or exceed OEM standards for fit, form, and function.
