Detailed Description

DuraGo BR900390 is a rear brake rotor for 2007-2018 Acura RDX and 2005-2016 Honda CR-V applications. The rotor is manufactured from cast iron in a full cast construction, with a solid braking surface and non-directional finish to support even pad contact during service replacement. Its drum-in-hat configuration, 5-bolt mounting pattern, and 114.3 mm bolt circle match the specified rear fitment requirements for these vehicles. DuraGo has a long history in aftermarket brake components, and its brake drum and rotor program is produced in ISO-certified factories with attention to fit, form, and function. This part cross-references Raybestos Brakes 980294 for the same application.

Common Uses

• Replacing a worn rear rotor on a 2007-2018 Acura RDX
• Replacing a worn rear rotor on a 2005-2016 Honda CR-V
• Correcting brake pulsation caused by rotor wear or thickness variation
• Restoring rear brake surface condition after scoring or heat damage
• Addressing noise or uneven pad contact linked to rotor condition

Installation Notes and Tips

Confirm rear fitment by matching the vehicle year, make, model, and rotor dimensions before installation. Inspect brake pads, caliper hardware, and hub condition at the same time so the new rotor seats properly. Clean the rotor and hub mating surfaces before assembly, and follow the vehicle manufacturer’s torque specifications during reinstallation. For best results, bed in the brake pads according to the pad manufacturer’s procedure after service.

Quality Assurance

DuraGo manufactures this rotor in ISO-certified factories and builds its brake program around fit, form, and function requirements. The BR900390 is engineered as a direct replacement for the listed rear applications and is backed by DuraGo’s aftermarket brake manufacturing standards.
