Pontiac Grand Prix Disc Brake Rotor and Hub Assembly Kit in US

On Pontiac Grand Prix 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 Grand Prix. When a seized caliper damages the Grand Prix rotor surface, or when hub bearing noise develops alongside worn rotors on your Pontiac Grand Prix, all friction and hub components require replacement simultaneously.

Why the Pontiac Grand Prix Needs a Kit Rather Than Individual Components

New brake pads on your Pontiac Grand Prix 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 Pontiac Grand Prix, bedding-in is inconsistent, producing noise, vibration, and uneven wear. A GeoBrakes kit pairs pad and rotor from the same specification set for the Pontiac Grand Prix, ensuring the smoothest possible break-in and the most consistent long-term friction performance on your Grand Prix.

What Is Included in the Pontiac Grand Prix Rotor and Hub Assembly Kit

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

Signs Your Pontiac Grand Prix Rotor and Hub Assembly Kit Is Due

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

Frequently Asked Questions - Pontiac Grand Prix Rotor and Hub Assembly Kits

Should I replace rotor and hub assembly kits on both sides of my Pontiac Grand Prix?

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

Can I use the pads from the kit with my existing Pontiac Grand Prix rotors?

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

Does the Pontiac Grand Prix kit include the wheel bearing?

This depends on the specific Pontiac Grand Prix application. On many Grand Prix 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 Pontiac Grand Prix.
