DuraGo BR901028 Disc Brake Rotor - Rear

DuraGo BR901028 Rear Brake Rotor

The DuraGo BR901028 is a rear vented drum-in-hat disc brake rotor built from cast iron for select heavy-duty Chevrolet and GMC applications. It is engineered for fit, form, and function in the rear brake system, with a non-directional braking surface and full cast construction.

For Silverado 2500 HD, Silverado 3500 HD, Sierra 2500 HD, Sierra 3500 HD, and Suburban 3500 HD applications, this rotor supports direct replacement service where the original rear rotor is worn, scored, or below discard thickness.

Detailed Description

DuraGo manufactures aftermarket brake components through ISO-certified factories with attention to fit and dimensional consistency. BR901028 is a rear disc brake rotor for 2011-2026 Chevrolet Silverado 2500 HD, 2011-2026 Chevrolet Silverado 3500 HD SRW, 2011-2026 GMC Sierra 2500 HD, 2011-2026 GMC Sierra 3500 HD SRW, and 2016-2019 Chevrolet Suburban 3500 HD. This rotor uses a vented, drum-in-hat configuration and a non-directional braking surface to support even pad contact during service. The cast iron build and specified thickness dimensions make it a direct-service replacement for rear brake maintenance on these platforms. This part cross-references Raybestos Brakes 580876 for the same application.

What It Helps Address

• Rear brake pulsation from rotor wear or thickness variation
• Scoring, grooves, or heat checking on the braking surface
• Brake noise caused by uneven rotor contact
• Reduced braking performance from a rotor below discard thickness
• Service replacement needs on Silverado 2500 HD, Sierra 3500 HD, and related rear brake applications

Installation Notes and Tips

Verify rotor dimensions, hub fitment, and rear axle configuration before installation. Clean the hub mounting surface thoroughly to reduce runout concerns, and inspect pads, calipers, and hardware condition during brake service. Because this rotor is non-directional and not slotted or cross-drilled, installation is straightforward when matched to the correct rear application.

Quality Assurance

DuraGo states that its brake drum and rotor program is produced in ISO-certified factories and built to meet fit, form, and function requirements. The BR901028 is part of that cataloged brake program for professional replacement service.
