Detailed Product Overview
DuraGo manufactures this rotor through ISO-certified factories with attention to fit, form, and function. The BR900808 uses cast iron construction and a full-cast design to meet the dimensional requirements of rear brake systems on covered Audi platforms. Its 11.81-inch outside diameter, 1.42-inch overall height, and solid rotor profile make it a direct-match option for vehicles that specify a conventional rear rotor rather than a vented design.
Fitment coverage includes 2021-2025 Audi A4 Quattro rear, 2018-2025 Audi A5 Sportback rear, 2017-2020 Audi A4 rear, 2008-2017 Audi A5 Quattro rear, 2009-2017 Audi Q5 rear, 2010-2016 Audi A4 rear, 2013-2016 Audi A4 allroad rear, 2010-2016 Audi A4 Quattro rear, 2010-2016 Audi A5 rear, 2013-2016 Audi allroad rear, 2012-2013 Audi A6 rear, 2013 Audi A6 Quattro rear, 2009 Audi A4 rear with 300 mm rotor diameter, and 2009 Audi A4 Quattro rear with 300 mm rotor diameter.
This part cross-references Raybestos Brakes (e.g., 980694, 980881) for the same application.
Common Issues This Rotor Can Address
- Rear brake pulsation caused by rotor wear or thickness variation
- Brake noise related to worn or uneven rear rotor surfaces
- Reduced braking consistency from a rotor below discard thickness
- Corrosion-related rotor deterioration on the braking surface
- Fitment replacement needs for Audi rear brake service
Installation Notes and Tips
Confirm rotor diameter, center hole diameter, bolt pattern, and solid rear rotor specification before installation. Measure the existing rotor and compare it to the listed 300 mm outside diameter, 68 mm center hole, 112 mm bolt circle, and 5-bolt configuration to verify application match. Inspect pads, caliper hardware, and hub condition during service so the new rotor seats evenly and the braking surface wears correctly.
Quality Assurance
DuraGo backs this rotor with manufacturing standards focused on fit, form, and function. The brand’s brake drum and rotor program is produced in ISO-certified factories and supported by long-standing aftermarket cataloging experience for Audi brake applications.
