Buick Regal Disc Brake Rotor and Hub Assembly Kit in US

On Buick Regal vehicles where the brake rotor and wheel hub share a single integrated casting, a rotor and hub assembly kit is the most complete way to restore full brake corner performance on your Regal. When a seized caliper damages the Regal rotor surface, or when hub bearing noise develops alongside worn rotors on your Buick Regal, all friction and hub components require replacement simultaneously.

Why the Buick Regal Needs a Kit Rather Than Individual Components

New brake pads on your Buick Regal must bed into the rotor surface during the first 200 to 300 kilometres. When the pad compound and rotor surface finish are mismatched on the Buick Regal, bedding-in is inconsistent, producing noise, vibration, and uneven wear. A GeoBrakes kit pairs pad and rotor from the same specification set for the Buick Regal, ensuring the smoothest possible break-in and the most consistent long-term friction performance on your Regal.

What Is Included in the Buick Regal Rotor and Hub Assembly Kit

The kit for your Buick Regal includes the integrated rotor and hub assembly at OEM specification for the Regal hub geometry, brake pads in ceramic or semi-metallic formulation matched to the Buick Regal rotor surface finish, caliper hardware with slide pins and anti-rattle clips for correct caliper operation on your Regal, and rotor mounting hardware where required by the Buick Regal application.

Signs Your Buick Regal Rotor and Hub Assembly Kit Is Due

• Regal rotor surfaces scored, deeply grooved, or below minimum thickness specification
• Wheel bearing noise on your Buick Regal, humming or rumbling changing pitch during cornering
• Excessive wheel play or looseness on the Regal detected during a manual push-pull inspection
• Steering wheel or floor vibration on your Buick Regal at highway speed from rotor runout
• ABS warning light on your Regal caused by hub bearing affecting the wheel speed sensor air gap
• Damaged or stripped wheel studs on the Buick Regal requiring hub replacement alongside rotor service

Our vehicle selector confirms the correct kit for the Buick Regal left and right positions before purchase, with full manufacturer warranty coverage across all included components for your Regal.

Frequently Asked Questions - Buick Regal Rotor and Hub Assembly Kits

Should I replace rotor and hub assembly kits on both sides of my Buick Regal?

Yes. Replacing both left and right on the same axle of your Buick Regal ensures balanced braking, even wear, and consistent vehicle handling. Both assemblies have experienced the same service conditions on the Regal and are at a comparable stage of wear.

Can I use the pads from the kit with my existing Buick Regal rotors?

While the pads will physically fit existing Regal rotors, it is strongly recommended to install new pads on a new rotor surface. Worn Buick Regal rotors have an uneven profile that prevents new pads from bedding in correctly, producing vibration, noise, and accelerated pad wear on your Regal.

Does the Buick Regal kit include the wheel bearing?

This depends on the specific Buick Regal application. On many Regal front-wheel-drive platforms, the wheel bearing is a separate component not included in the rotor-hub casting. Use the GeoBrakes vehicle selector to confirm what is included in the kit for your Buick Regal.
