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