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