Product Details

Part number BD8839 is part of DuraGo’s brake drum and rotor program, a catalog-focused aftermarket line manufactured in ISO-certified factories to meet fit, form, and function requirements. This rear drum is specified for a wide range of rear brake applications, including 1975-1992 Chevrolet Camaro rear, 1974-1992 Pontiac Firebird rear, and 1982-1991 Chevrolet S10 rear. It also covers many GM A-body and G-body applications such as the Chevrolet Monte Carlo, Buick Regal, Oldsmobile Cutlass, Pontiac Grand Prix, and Chevrolet El Camino.

This part cross-references Anchor 2091 and CSF 2027 for the same application.

Common Problems This Drum Addresses

  • Rear brake pulsation from worn or out-of-round drums
  • Reduced braking consistency from heat buildup in the drum assembly
  • Brake surface wear that exceeds discard diameter limits
  • Fitment issues on 9.5-inch rear drum brake applications
  • Noise or vibration caused by damaged drum surfaces

Installation Notes and Tips

Verify the vehicle’s rear brake configuration before ordering, especially on models with notes such as 9 1/2 inch rear drum, heavy-duty exclusions, or cut-out axle cover requirements. Confirm bolt circle diameter, center hole diameter, and brake surface width against the existing drum and hub before installation. For best results, inspect rear shoes, hardware, and wheel cylinders at the same time so the new drum can seat evenly.

Quality Assurance

DuraGo manufactures this brake drum in ISO-certified factories and builds the product line around fit, form, and function requirements for aftermarket service. BD8839 is engineered for direct replacement use on listed rear brake applications, including Chevrolet Camaro, Pontiac Firebird, and Chevrolet S10 fitments.
