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