DuraGo BD8939-01 Rear Brake Drum

The DuraGo Titanium Series brake drum is built for rear brake service on a wide range of GM and Cadillac applications, including Chevrolet Malibu, Pontiac Grand Am, and Buick Century models. Part number BD8939-01 combines a corrosion-resistant exterior coating with a titanium gray finish that suits open-wheel designs while helping protect the drum from rust.

Key Features

Cast iron / steel top construction for dependable brake performance
Rust-resistant coating on the exterior, hat, and edge
Outer cooling fins for improved heat management
Nominal drum diameter: 8.8 in. (223.5 mm)
Maximum discard diameter: 8.91 in. (226.3 mm)
5-bolt pattern with 4.5 in. bolt circle diameter
Brake surface width: 2.14 in. (54.4 mm)
Center hole diameter: 2.78 in. (70.6 mm)

Product Details

BD8939-01 is a rear brake drum engineered in an ISO-certified factory to meet fit, form, and function requirements. The composite construction, 10.87 in. outside diameter, and 2.76 in. overall height support proper drum brake service on compatible rear axle applications. This DuraGo brake drum is a practical OE-style replacement for vehicles such as Chevrolet Classic, Oldsmobile Alero, Pontiac Bonneville, and Buick LeSabre, where consistent braking surface dimensions and corrosion protection matter.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Brake Issues It Can Address

Rear brake pulsation caused by worn or out-of-spec drum surfaces
Rust buildup on the drum exterior and hat area
Reduced braking consistency from heat-related wear
Noise or vibration from damaged or uneven drum surfaces
Service replacement needs on rear drum brake systems

Installation Notes and Tips

Verify drum diameter, bolt circle, and center hole dimensions before installation. This rear drum is listed for specific applications including 2004-2005 Chevrolet Malibu rear, 1999-2005 Pontiac Grand Am rear, and 1993-2003 Buick Century rear. Some fitments note exceptions such as heavy-duty brake packages or specific bolt-circle requirements, so match the vehicle’s brake configuration before ordering. Part number BD8939-01 should be installed on the rear position only for the listed applications.

Quality Assurance

DuraGo manufactures the Titanium Series brake drums in an ISO-certified facility and builds them from experience developed over decades in the automotive aftermarket. The corrosion-resistant coating and controlled manufacturing process support consistent fitment and durable service on rear drum brake applications.
