GeoBrakes stocks OEM-grade brake drums confirmed to fit the Saturn Sw2, the cast-iron components that form the friction surface for the Sw2 drum brake shoes. Available in standard and corrosion-coated configurations for your Sw2, every drum is manufactured to the correct inner diameter, wall thickness, and surface finish for the Saturn Sw2

The brake drum on the Saturn Sw2 is the rotating cast-iron bowl that the Sw2 drum brake shoes press against to slow your vehicle. Mounted to the rear axle hub of your Saturn Sw2, 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 Sw2 vehicles, Saturn Sw2 brake drums fully enclose the shoe assembly, which means wear and damage often goes unnoticed until braking performance on the Saturn Sw2 is noticeably affected.
Standard OEM-Grade Drums for the Saturn Sw2
Standard OEM-grade cast-iron drums for the Saturn Sw2 are manufactured to the original equipment diameter, wall thickness, and surface finish specification for your Sw2. They are the direct replacement for the factory Sw2 drum with no modification required.
Coated Brake Drums for the Saturn Sw2
Coated Saturn Sw2 brake drums feature a corrosion-resistant coating applied to the external drum surfaces of your Sw2, the hat section, outer wall, and wheel mounting face. Surface rust is a common issue on Saturn Sw2 drum brake vehicles in US, particularly during periods of non-use in winter when moisture and salt collect inside the Sw2 wheel well. A coated drum on your Saturn Sw2 resists surface rust that can transfer to the wheel mounting face, making future drum removal significantly easier at the next Sw2 brake service.
Saturn Sw2 brake drum replacement requires matching the correct inner diameter, wall thickness, bolt circle, hub bore, and drum offset for your Sw2. Errors in any of these dimensions produce incorrect shoe-to-drum clearance, uneven wear, and braking problems on the Saturn Sw2. Our vehicle selector eliminates those risks by confirming the correct drum for the Saturn Sw2 exact year, make, model, and axle. Coated Sw2 drum options are available for vehicles with heavy salt exposure.
How long do brake drums last on a Saturn Sw2?
Saturn Sw2 brake drums typically last 150,000 to 200,000 kilometres with periodic resurfacing, significantly longer than disc brake rotors on the Sw2. Each resurfacing removes material from the Sw2 drum and reduces wall thickness. Once the Saturn Sw2 drum reaches its maximum allowable inner diameter, it must be replaced rather than turned again.
Should I replace brake drums on my Saturn Sw2 in pairs?
Yes. Replace both Saturn Sw2 drums on the same axle to maintain balanced braking. Drums of different inner diameters on the Sw2 create uneven friction forces, causing the Saturn Sw2 to pull to the fresher-drum side during braking.
Should I replace drums and shoes at the same time on my Saturn Sw2?
Yes, it is strongly recommended for the Saturn Sw2. New shoes on a scored or out-of-round Sw2 drum wear unevenly from day one. New Saturn Sw2 drums with old shoes that have worn to match the old drum surface will contact the new bore incorrectly. Replacing both together on the Sw2 ensures proper break-in and maximum service life from both components.
