Detailed Description

DuraGo BR31254 is engineered for front brake applications that require a rotor and hub assembly with integrated service components. The vented rotor construction supports heat management during braking, while the non-directional surface helps provide consistent pad contact during rotor service. With the ABS tone ring, bearing cups, and wheel studs included, this assembly is built to match the fit, form, and function expected in professional brake repair.

This part fits 1991-2003 Chevrolet and GMC front applications, including 1994-2003 Chevrolet S10 front, 1994-2003 GMC Sonoma front, 1995-1997 Chevrolet Blazer front, 1992-1997 GMC Jimmy front, 1992-1994 Chevrolet S10 Blazer front, 1991 GMC Sonoma front, 1991 GMC S15 Jimmy front, and 1996-2000 Isuzu Hombre front. It also cross-references Monroe Shocks & Struts 5575 for the same application.

What It Helps Address

• Brake pulsation caused by worn or out-of-spec rotor surfaces
• Front-end brake noise related to rotor wear or uneven contact
• ABS-related service needs when the tone ring is part of the assembly
• Hub and bearing service on vehicles using an integrated rotor/hub design
• Fitment issues from incorrect stud pattern or bearing cup configuration

Installation Notes and Tips

Verify rotor outside diameter, bolt circle diameter, stud thread size, and bearing fitment before installation. Clean the hub mounting surface thoroughly and inspect pads, caliper hardware, and wheel bearings for wear before completing the brake job. Because this is a front rotor and hub assembly, confirm the vehicle’s front application and ABS configuration against the part listing before service.
