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