What This Brake Drum Helps Address
- Rear brake pulsation caused by worn or out-of-round drum surfaces
- Reduced braking consistency from excessive drum wear
- Noise from damaged or heat-affected rear drum components
- Brake service needs on Chevrolet Spark, Aveo, and Pontiac G3 rear drum setups
- Replacement of drums that have reached the discard diameter limit
Installation Notes and Tips
Verify rear axle fitment by year, make, model, and hub configuration before installation. Some 2004 Chevrolet Aveo and 2006 Chevrolet Aveo5 applications note hub not included, so confirm the vehicle’s rear brake assembly matches the listing before ordering. Inspect shoes, hardware, wheel cylinders, and the drum’s mating surfaces during service, and measure the existing drum before reuse or replacement. The BD920110 is a rear brake drum only and should be matched to the vehicle’s specified brake dimensions.
