Disc Brake Rotor and Hub Assemblies in Canada

On many front-wheel-drive cars and crossovers, the brake rotor and wheel hub are manufactured as a single integrated assembly rather than separate serviceable components. This design means that when rotor surfaces wear below minimum thickness, or when hub bearing failure or wheel stud damage is detected, the complete assembly requires replacement as a single unit. A rotor and hub assembly from GeoBrakes delivers both components to OEM specification in one part number, with pre-set dimensional relationships that eliminate the need to source and match separate components.

When Do You Need a Rotor and Hub Assembly?

The primary indicator is worn rotor surfaces, scoring, deep grooves, or thickness below minimum specification, combined with a vehicle design where the rotor cannot be separated from the hub without specialized machining equipment. Additional triggers for assembly replacement include: wheel bearing noise (humming or rumbling that changes pitch during cornering), excessive wheel play detected during a push-pull inspection, damaged or broken wheel studs, and ABS warning lights caused by the hub bearing affecting the integrated wheel speed sensor air gap.

Benefits of a Pre-Assembled Rotor and Hub Unit

• Single part number replaces two worn components simultaneously, no separate component sourcing or matching
• Factory-balanced assembly, no individual balancing or rotor-to-hub run-out matching required
• Pre-set bearing preload on designs where the bearing is integrated into the hub casting
• Eliminates the labour of pressing bearings, transferring wheel studs, or torquing separate components during installation
• OEM-equivalent dimensional accuracy ensures the correct ABS sensor air gap on integrated hub bearing designs

Why GeoBrakes for Rotor and Hub Assemblies?

Rotor and hub assemblies are among the most highly vehicle-specific brake components in the catalogue, rotor diameter, hub bolt circle, hub bore diameter, and bearing specification must all match your exact vehicle. Our vehicle selector confirms the correct assembly for your year, make, model, and wheel position before purchase. As an authorized retailer, every assembly carries the full manufacturer warranty covering both the rotor surface and the hub construction.

Frequently Asked Questions About Rotor and Hub Assemblies

Q: Can I replace just the rotor on a rotor-hub assembly design?

A: On most integrated designs, separating the rotor from the hub requires machining and is not a practical field service procedure. Complete assembly replacement is the correct and most cost-effective approach when either component is worn.

Q: Should I replace rotor and hub assemblies in pairs?

A: Yes. Replacing as an axle pair, both left and right, ensures balanced braking, even wear, and consistent vehicle handling. Both assemblies have experienced the same service conditions and are at a similar stage of wear.

Q: Does a rotor and hub assembly include the wheel bearing?

A: This varies by design. On many FWD vehicles, the bearing is a separate pressed-in unit; the hub assembly includes only the hub and rotor. On other designs, the bearing is integral to the hub casting. Use the GeoBrakes vehicle selector to confirm exactly what is included for your vehicle.
