Detailed Description

DuraGo manufactures aftermarket brake components through ISO-certified factories, with a focus on fit, form, and function. The BR900838 rear rotor is built for 2005-2012 Acura RL vehicles and follows the listed OE-style dimensions, including a 12.2-inch outside diameter, 5 mounting bolt holes, and a vented drum-in-hat layout. Its cast iron, full cast construction supports stable braking characteristics and dependable rotor replacement service.

Use BR900838 when replacing a worn rear rotor on an Acura RL and you need a part that matches the vehicle’s rear brake geometry. The non-directional surface simplifies service preparation, while the specified discard and nominal thickness measurements help confirm replacement timing during brake inspection.

Common Reasons for Replacement

  • Rear brake pulsation or vibration during stopping
  • Rotor wear that reaches discard thickness
  • Brake noise caused by uneven rotor surfaces
  • Reduced braking consistency on Acura RL rear brakes
  • Service replacement during rear brake maintenance

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and center bore before installation. Clean the hub mounting surface thoroughly to help prevent runout-related brake issues, and inspect pads, calipers, and hardware condition at the same time. For best results, follow the vehicle service manual for torque specifications and bedding procedures after installation.

Quality Assurance

DuraGo states that its brake drum and rotor program is manufactured in ISO-certified factories and built to meet fit, form, and function requirements. The BR900838 is part of that professional-grade cataloging approach for rear brake service on the Acura RL.
