DuraGo BR31227 Rear Disc Brake Rotor

The DuraGo BR31227 is a rear solid disc brake rotor built from cast iron for direct-fit brake service on select Honda and Acura applications. It combines OE-style dimensions with a non-directional brake surface to support consistent pad contact and predictable braking performance.

Key Features

  • Cast iron construction with full cast design
  • Solid, conventional rear disc brake rotor
  • Non-directional brake surface for even pad bedding
  • 5-bolt mounting pattern
  • Outside diameter: 10.22 in. (259.6 mm)
  • Nominal thickness: 0.35 in. (9 mm)
  • Discard thickness: 0.31 in. (8 mm)
  • Center hole diameter: 2.52 in. (64.1 mm)
  • Mounting bolt hole circle diameter: 4.5 in. (114.3 mm)

Detailed Description

DuraGo BR31227 is engineered as a conventional rear brake rotor for vehicles that use a solid rotor design. Its cast iron construction supports stable braking characteristics, while the non-directional surface helps the brake pads seat evenly during service. This rotor matches the dimensional requirements needed for rear brake replacement on 2006-2011 Honda Civic, rear; 2006-2008 Acura CSX, rear; and 1997-2001 Honda Prelude, rear. The BR31227 part number is also referenced in aftermarket catalogs for the same application, including 42510S30A00 and PRT5159.

DuraGo manufactures brake drums and rotors through ISO-certified factories and focuses on fit, form, and function. That manufacturing approach makes the BR31227 a practical choice when replacing a worn rear rotor on a Honda Civic, Acura CSX, or Honda Prelude.

What This Rotor Helps Address

  • Brake pulsation caused by rotor wear or thickness variation
  • Reduced braking consistency from a worn rear rotor surface
  • Noise related to uneven pad-to-rotor contact
  • Service replacement for a rotor that has reached discard thickness
  • Rear brake maintenance on select Honda and Acura vehicles

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 issues. After installation, follow proper brake bedding procedures and confirm the rotor is used in the rear position only. Fits 2006-2011 Honda Civic, rear. Fits 2006-2008 Acura CSX, rear. Fits 1997-2001 Honda Prelude, rear.

Quality Assurance

DuraGo brake rotors are produced in ISO-certified factories and built to meet fit, form, and function requirements for aftermarket brake service. The BR31227 reflects DuraGo’s long-running brake program focused on catalog accuracy and application coverage.
