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