DuraGo BR901030 Disc Brake Rotor - Rear

DuraGo BR901030 Rear Brake Rotor

The DuraGo BR901030 is a vented drum-in-hat disc brake rotor built from cast iron for rear brake service on heavy-duty applications. It is engineered for 2011-2019 Chevrolet Silverado 3500 HD and 2011-2019 GMC Sierra 3500 HD DRW rear disc brake rotor and hub assembly applications.

Key Features

• Cast iron, full cast construction for consistent braking performance
• Vented rotor design for rear brake heat management
• Drum-in-hat rotor configuration for DRW rear applications
• Non-directional brake surface for straightforward service preparation
• 8 mounting bolt holes with 180 mm bolt circle diameter
• Outside diameter: 355 mm (13.98 in)
• Center hole diameter: 130 mm (5.12 in)
• Nominal thickness: 40 mm (1.57 in); discard thickness: 38 mm (1.5 in)

Detailed Description

DuraGo BR901030 is a rear disc brake rotor and hub assembly component made for heavy-duty truck braking systems. The cast iron, vented construction supports stable braking under load, while the drum-in-hat design matches the rear brake layout used on dual rear wheel Silverado 3500 HD and Sierra 3500 HD models. DuraGo manufactures this rotor through ISO-certified factories and focuses on fit, form, and function for aftermarket brake service. This part cross-references Raybestos Brakes 580895 for the same application.

What It Helps Address

• Rear brake pulsation from worn or uneven rotor surfaces
• Brake noise caused by rotor wear or surface irregularity
• Reduced braking consistency on heavy-duty rear axle service
• Rotor thickness loss that reaches service limits
• Fitment issues when replacing the rear drum-in-hat rotor on DRW trucks

Installation Notes and Tips

Confirm rear axle configuration and DRW application before ordering. Verify rotor dimensions, bolt pattern, center bore, and thickness against the existing part on the vehicle. Clean the hub mounting surface thoroughly before installation to help prevent runout-related brake complaints. For best results, inspect pads, calipers, and related rear brake components at the same time.

Quality Assurance

DuraGo has over 45 years of aftermarket manufacturing experience and produces brake components in ISO-certified factories. The BR901030 is built to meet fit, form, and function requirements for the listed Chevrolet Silverado 3500 HD and GMC Sierra 3500 HD rear applications.
