The brake drum on the Oldsmobile Delta 88 is the rotating cast-iron bowl that the Delta 88 drum brake shoes press against to slow your vehicle. Mounted to the rear axle hub of your Oldsmobile Delta 88, 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 Delta 88 vehicles, Oldsmobile Delta 88 brake drums fully enclose the shoe assembly, which means wear and damage often goes unnoticed until braking performance on the Oldsmobile Delta 88 is noticeably affected.
Standard OEM-Grade Drums for the Oldsmobile Delta 88
Standard OEM-grade cast-iron drums for the Oldsmobile Delta 88 are manufactured to the original equipment diameter, wall thickness, and surface finish specification for your Delta 88. They are the direct replacement for the factory Delta 88 drum with no modification required.
Coated Brake Drums for the Oldsmobile Delta 88
Coated Oldsmobile Delta 88 brake drums feature a corrosion-resistant coating applied to the external drum surfaces of your Delta 88, the hat section, outer wall, and wheel mounting face. Surface rust is a common issue on Oldsmobile Delta 88 drum brake vehicles in US, particularly during periods of non-use in winter when moisture and salt collect inside the Delta 88 wheel well. A coated drum on your Oldsmobile Delta 88 resists surface rust that can transfer to the wheel mounting face, making future drum removal significantly easier at the next Delta 88 brake service.
Oldsmobile Delta 88 brake drum replacement requires matching the correct inner diameter, wall thickness, bolt circle, hub bore, and drum offset for your Delta 88. Errors in any of these dimensions produce incorrect shoe-to-drum clearance, uneven wear, and braking problems on the Oldsmobile Delta 88. Our vehicle selector eliminates those risks by confirming the correct drum for the Oldsmobile Delta 88 exact year, make, model, and axle. Coated Delta 88 drum options are available for vehicles with heavy salt exposure.
How long do brake drums last on a Oldsmobile Delta 88?
Oldsmobile Delta 88 brake drums typically last 150,000 to 200,000 kilometres with periodic resurfacing, significantly longer than disc brake rotors on the Delta 88. Each resurfacing removes material from the Delta 88 drum and reduces wall thickness. Once the Oldsmobile Delta 88 drum reaches its maximum allowable inner diameter, it must be replaced rather than turned again.
Should I replace brake drums on my Oldsmobile Delta 88 in pairs?
Yes. Replace both Oldsmobile Delta 88 drums on the same axle to maintain balanced braking. Drums of different inner diameters on the Delta 88 create uneven friction forces, causing the Oldsmobile Delta 88 to pull to the fresher-drum side during braking.
Should I replace drums and shoes at the same time on my Oldsmobile Delta 88?
Yes, it is strongly recommended for the Oldsmobile Delta 88. New shoes on a scored or out-of-round Delta 88 drum wear unevenly from day one. New Oldsmobile Delta 88 drums with old shoes that have worn to match the old drum surface will contact the new bore incorrectly. Replacing both together on the Delta 88 ensures proper break-in and maximum service life from both components.
