Pontiac Bonneville Disc Brake Rotor and Hub Assembly Kit in US

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

Why the Pontiac Bonneville Needs a Kit Rather Than Individual Components

New brake pads on your Pontiac Bonneville 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 Bonneville, 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 Bonneville, ensuring the smoothest possible break-in and the most consistent long-term friction performance on your Bonneville.

What Is Included in the Pontiac Bonneville Rotor and Hub Assembly Kit

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

Signs Your Pontiac Bonneville Rotor and Hub Assembly Kit Is Due

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

Why GeoBrakes for the Pontiac Bonneville Rotor and Hub Assembly Kit

Rotor and hub assemblies for the Pontiac Bonneville are among the most vehicle-specific brake components in the catalogue. Hub bolt circle, rotor diameter, hub bore, and the wheel speed sensor interface are all specific to the Pontiac Bonneville. Our vehicle selector confirms the correct kit for the Pontiac Bonneville left and right positions before purchase, with full manufacturer warranty coverage across all included components for your Bonneville.

Frequently Asked Questions - Pontiac Bonneville Rotor and Hub Assembly Kits

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

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

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

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

Does the Pontiac Bonneville kit include the wheel bearing?

This depends on the specific Pontiac Bonneville application. On many Bonneville 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 Bonneville.
