GeoBrakes stocks OEM-grade brake drums confirmed to fit the Scion Iq, the cast-iron components that form the friction surface for the Iq drum brake shoes. Available in standard and corrosion-coated configurations for your Iq, every drum is manufactured to the correct inner diameter, wall thickness, and surface finish for the Scion Iq

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