GeoBrakes stocks OEM-grade brake drums confirmed to fit the Geo Prizm, the cast-iron components that form the friction surface for the Prizm drum brake shoes. Available in standard and corrosion-coated configurations for your Prizm, every drum is manufactured to the correct inner diameter, wall thickness, and surface finish for the Geo Prizm

The brake drum on the Geo Prizm is the rotating cast-iron bowl that the Prizm drum brake shoes press against to slow your vehicle. Mounted to the rear axle hub of your Geo Prizm, it spins with the wheel and provides the friction surface that the shoes contact under braking. Unlike brake rotors, which can be visually inspected from outside the wheel on many Prizm vehicles, Geo Prizm brake drums fully enclose the shoe assembly, which means wear and damage often goes unnoticed until braking performance on the Geo Prizm is noticeably affected.
Standard OEM-Grade Drums for the Geo Prizm
Standard OEM-grade cast-iron drums for the Geo Prizm are manufactured to the original equipment diameter, wall thickness, and surface finish specification for your Prizm. They are the direct replacement for the factory Prizm drum with no modification required.
Coated Brake Drums for the Geo Prizm
Coated Geo Prizm brake drums feature a corrosion-resistant coating applied to the external drum surfaces of your Prizm, the hat section, outer wall, and wheel mounting face. Surface rust is a common issue on Geo Prizm drum brake vehicles in US, particularly during periods of non-use in winter when moisture and salt collect inside the Prizm wheel well. A coated drum on your Geo Prizm resists surface rust that can transfer to the wheel mounting face, making future drum removal significantly easier at the next Prizm brake service.
Geo Prizm brake drum replacement requires matching the correct inner diameter, wall thickness, bolt circle, hub bore, and drum offset for your Prizm. Errors in any of these dimensions produce incorrect shoe-to-drum clearance, uneven wear, and braking problems on the Geo Prizm. Our vehicle selector eliminates those risks by confirming the correct drum for the Geo Prizm exact year, make, model, and axle. Coated Prizm drum options are available for vehicles with heavy salt exposure.
How long do brake drums last on a Geo Prizm?
Geo Prizm brake drums typically last 150,000 to 200,000 kilometres with periodic resurfacing, significantly longer than disc brake rotors on the Prizm. Each resurfacing removes material from the Prizm drum and reduces wall thickness. Once the Geo Prizm drum reaches its maximum allowable inner diameter, it must be replaced rather than turned again.
Should I replace brake drums on my Geo Prizm in pairs?
Yes. Replace both Geo Prizm drums on the same axle to maintain balanced braking. Drums of different inner diameters on the Prizm create uneven friction forces, causing the Geo Prizm to pull to the fresher-drum side during braking.
Should I replace drums and shoes at the same time on my Geo Prizm?
Yes, it is strongly recommended for the Geo Prizm. New shoes on a scored or out-of-round Prizm drum wear unevenly from day one. New Geo Prizm drums with old shoes that have worn to match the old drum surface will contact the new bore incorrectly. Replacing both together on the Prizm ensures proper break-in and maximum service life from both components.
