Nissan Micra Drum Brake and Hub Assembly in US

On many rear-wheel-drive Nissan Micra vehicles, pickup trucks, and older passenger cars, the brake drum and wheel hub are manufactured as a single integrated casting rather than separate serviceable components on the Micra. When the Micra drum surface wears beyond its maximum allowable diameter or develops damage requiring replacement, and the hub bearing, wheel studs, or hub flange on the Nissan Micra simultaneously require attention, sourcing a separate drum and hub for the Micra produces two separate part numbers, two separate installation operations, and two separate dimensional tolerances that must align correctly. An integrated drum and hub assembly from GeoBrakes eliminates that complexity for the Nissan Micra.

Signs Your Nissan Micra Drum and Hub Assembly Needs Replacing

• Micra drum inner surface scored, grooved, or worn beyond maximum inner diameter specification
• Wheel bearing noise from the Nissan Micra rear axle, humming or rumbling that changes pitch with speed
• Damaged, stripped, or broken wheel studs on the Micra requiring hub replacement
• Wheel wobble or looseness on the Nissan Micra detected during a push-pull hand inspection
• Cracks visible in the Micra drum casting near the stud circle or mounting flange
• Nissan Micra drum has been machined to its wear limit and cannot be resurfaced again

Benefits of a Pre-Assembled Drum and Hub Unit for the Nissan Micra

• Single part number covers both Micra drum surface and hub, no separate sourcing or compatibility matching
• Wheel studs on the Nissan Micra pre-installed and torqued to specification, no stud transfer from the old hub required
• Bearing race pre-pressed where applicable on the Micra, correct bearing preload set in the factory
• OEM-equivalent drum-to-hub dimensional relationship on the Nissan Micra, correct geometry for the brake shoe contact arc
• Eliminates the risk of misalignment from separately pressed bearing and drum components on the Micra

Why GeoBrakes for the Nissan Micra Drum Brake and Hub Assembly

Nissan Micra drum and hub assemblies are highly vehicle-specific. The drum inner diameter, hub bolt circle, hub bore, stud specification, and bearing interface on the Micra must all match the exact Nissan Micra and axle position. Our vehicle selector confirms the correct assembly for the Nissan Micra year, make, model, and axle before purchase. Order alongside brake shoes, a hardware kit, and wheel cylinders for a complete Micra rear drum brake overhaul from a single delivery.

Frequently Asked Questions - Nissan Micra Drum Brake and Hub Assembly

Can the drum and hub on my Nissan Micra be separated for individual replacement?

On Nissan Micra vehicles that use an integrated drum-hub casting, separating the components is not a practical service procedure without machining equipment. Complete assembly replacement is the correct approach when either the Micra drum surface is worn or the hub bearing or studs require service on your Nissan Micra.

Should drum and hub assemblies on my Nissan Micra be replaced in pairs?

Yes. Replacing as an axle pair on the Nissan Micra, both left and right rear, ensures balanced braking, even drum wear, and consistent Micra vehicle handling. Both assemblies on the Nissan Micra have operated under identical service conditions.

Does the Nissan Micra assembly include the wheel bearing?

This depends on the specific Micra design. On many Micra applications, the bearing is a separate pressed-in race or bolt-on cartridge not included in the Micra drum-hub casting. Use the GeoBrakes vehicle selector to confirm what is included for your Nissan Micra and axle configuration.
