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