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