GeoBrakes stocks complete brake drum kits confirmed to fit the Lexus Nx300h, pairing OEM-grade brake drums at the correct inner diameter for the Nx300h with matched drum brake shoes and hardware for a full rear drum brake overhaul on your Lexus Nx300h in a single package. Every kit ensures drums and shoes are replaced together on the Nx300h, the only way to achieve correct contact geometry and maximum service life from both components. Each kit ships with a 100% fitment guarantee and free delivery across Canada on orders over $99.
A brake drum kit for the Lexus Nx300h addresses the most common brake service shortcut: replacing shoes on a worn Nx300h drum, or fitting new drums with glazed, worn shoes. Either combination prevents correct break-in on the Lexus Nx300h. New shoes have a specific arc radius that must contact a fresh drum surface across the full lining width on your Nx300h. A GeoBrakes drum kit eliminates that incompatibility by delivering matched drums and shoes confirmed for your Lexus Nx300h in a single order.
The kit for your Lexus Nx300h includes OEM-spec cast-iron brake drums at the correct inner diameter for the Nx300h for both left and right rear wheels, drum brake shoes with OEM-grade friction lining matched to the Lexus Nx300h drum bore and wheel cylinder specification, a brake hardware kit with return springs, hold-down hardware, and self-adjusters specific to the Nx300h, and drum retaining hardware where required by the Lexus Nx300h application.
Road salt and freeze-thaw cycles deteriorate every component in the Lexus Nx300h drum brake system over the same service interval. By the time a Nx300h drum is worn, the shoes are typically at or near minimum thickness, the hardware is corroded, and the wheel cylinder boots are deteriorating on your Lexus Nx300h. Replacing drums and shoes alone while leaving worn springs and seized adjusters on the Nx300h produces a service that underperforms within months.
Drum and shoe arc radius must match exactly for correct contact geometry on the Lexus Nx300h. An incorrect drum diameter or wrong-spec shoe lining for the Nx300h produces immediate uneven wear and noise. Every kit in the GeoBrakes catalogue is assembled for the Lexus Nx300h, drum diameter, shoe arc, and hardware spring rates all confirmed as a matched set specific to the Nx300h.
How do I know if I need a basic or full-service kit for my Lexus Nx300h?
A basic kit for the Lexus Nx300h is appropriate when the wheel cylinders have been recently replaced and show no signs of leaking. A full-service kit is the stronger choice during a high-mileage Nx300h overhaul, particularly on Canadian Lexus Nx300h vehicles with significant winter salt exposure.
Should I replace drum kits on both rear wheels of my Lexus Nx300h at the same time?
Yes. Always replace drum brake components on the Lexus Nx300h as an axle set, both left and right rear, to maintain balanced braking force. Drums and shoes at different wear stages on the Nx300h create uneven rear braking that pulls the vehicle to one side.
Can I install a brake drum kit on my Lexus Nx300h myself?
Rear drum brake service on the Lexus Nx300h is a moderately advanced DIY task. It requires removing the drum, dismantling the shoe assembly on the Nx300h, correctly routing return springs, and adjusting shoes to the correct drum clearance. A service manual specific to the Lexus Nx300h is essential.
