DuraGo BR31318 Rear Brake Rotor

The DuraGo BR31318 is a rear disc brake rotor built for specific Honda and Acura applications. It uses full cast iron construction and a solid, non-directional brake surface to support consistent braking performance on the vehicles listed below.

  • Solid rotor design with a non-directional brake surface
  • Outside diameter: 12.32 in. / 313 mm
  • Nominal thickness: 0.44 in. / 11.1 mm

Detailed Description

DuraGo BR31318 is a rear brake rotor engineered for 2003-2008 Honda Pilot and 2001-2006 Acura MDX applications. It is a drum-in-hat style rotor made from cast iron, with a solid rotor profile and non-directional braking surface to simplify service preparation. DuraGo manufactures brake drums and rotors through ISO-certified factories, with an emphasis on fit, form, and function for aftermarket replacement needs. This part cross-references Raybestos Brakes (e.g., 980032) for the same application.

What This Rotor Helps Address

  • Rear brake pulsation caused by worn or uneven rotor surfaces
  • Brake noise related to rotor wear or surface irregularity
  • Reduced braking consistency from a rotor below discard thickness
  • Service replacement needs on Honda Pilot and Acura MDX rear brake systems
  • Rotor replacement for drum-in-hat rear brake assemblies

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and hub fitment before installation. Clean the hub mounting surface thoroughly to help prevent runout-related brake pulsation. Because this rotor is non-directional, surface orientation is not a concern during installation, but proper brake service procedures should still be followed. Confirm rear application fitment for your exact year and model before ordering BR31318.

Quality Assurance

DuraGo has over 45 years of aftermarket manufacturing experience and produces brake components in ISO-certified factories. The BR31318 is built to meet fit, form, and function requirements for the listed Honda and Acura rear brake applications.
