Its vented design allows air to flow between the rotor surfaces, enhancing heat dissipation and reducing the risk of brake fade during extended use. With a nominal thickness of 0.87 inches (22 mm) and a discard thickness of 0.79 inches (20 mm), this rotor maintains structural integrity throughout its service life. The rotor’s overall height of 1.43 inches (36.2 mm) and outside diameter of 12.99 inches (330 mm) are engineered to fit a range of Audi vehicles, including the A4, A5, A6, A7, A8, and Q5 models, along with their Quattro and Sportback versions. The five mounting bolt holes with a 4.41 inch (112 mm) bolt circle diameter ensure secure attachment to the hub assembly. This rotor features a non-directional brake surface, allowing for flexible installation without concern for rotor orientation.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCompatible with Audi A4, A4 allroad, A4 Quattro\u003c\/li\u003e\n\u003cli\u003eFits Audi A5 Quattro, A5 Sportback\u003c\/li\u003e\n\u003cli\u003eSuitable for Audi A6, A6 allroad, A6 Quattro\u003c\/li\u003e\n\u003cli\u003eDesigned for Audi A7, A7 Quattro, A7 Sportback\u003c\/li\u003e\n\u003cli\u003eFits Audi A8 Quattro, Q5, Q5 PHEV, Q5 Sportback\u003c\/li\u003e\n\u003cli\u003eAlso compatible with Audi S4, S5, S5 Sportback, SQ5, SQ5 Sportback\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon Issues Addressed by This Rotor\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake rotor warping causing vibration during braking\u003c\/li\u003e\n\u003cli\u003eReduced braking efficiency due to worn or thin rotors\u003c\/li\u003e\n\u003cli\u003eOverheating and brake fade from insufficient heat dissipation\u003c\/li\u003e\n\u003cli\u003eUneven brake pad wear linked to rotor surface irregularities\u003c\/li\u003e\n\u003cli\u003eNoise and pulsation caused by damaged or out-of-spec rotors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eWhen installing the DuraGo BR901398 rotor, ensure the mounting surface is clean and free of rust or debris to promote proper seating. Since this rotor is non-directional, it can be installed on either side without concern for rotation direction. Verify that the rotor thickness is above the discard thickness of 0.79 inches (20 mm) before installation. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Torque mounting bolts to manufacturer specifications to avoid rotor distortion.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDuraGo manufactures the BR901398 rotor to meet or exceed OEM specifications for fit, form, and function.
