Pontiac Bonneville Brake Drum Kit in US

A brake drum kit for the Pontiac Bonneville addresses the most common brake service shortcut: replacing shoes on a worn Bonneville drum, or fitting new drums with glazed, worn shoes. Either combination prevents correct break-in on the Pontiac Bonneville. New shoes have a specific arc radius that must contact a fresh drum surface across the full lining width on your Bonneville. A GeoBrakes drum kit eliminates that incompatibility by delivering matched drums and shoes confirmed for your Pontiac Bonneville in a single order.

What Is Included in the Pontiac Bonneville Brake Drum Kit

The kit for your Pontiac Bonneville includes OEM-spec cast-iron brake drums at the correct inner diameter for the Bonneville for both left and right rear wheels, drum brake shoes with OEM-grade friction lining matched to the Pontiac Bonneville drum bore and wheel cylinder specification, a brake hardware kit with return springs, hold-down hardware, and self-adjusters specific to the Bonneville, and drum retaining hardware where required by the Pontiac Bonneville application.

Why American Conditions Make a Full Kit the Right Call for Your Pontiac Bonneville

Road salt and freeze-thaw cycles deteriorate every component in the Pontiac Bonneville drum brake system over the same service interval. By the time a Bonneville drum is worn, the shoes are typically at or near minimum thickness, the hardware is corroded, and the wheel cylinder boots are deteriorating on your Pontiac Bonneville. Replacing drums and shoes alone while leaving worn springs and seized adjusters on the Bonneville produces a service that underperforms within months.

Signs the Brake Drum Kit on Your Pontiac Bonneville Is Due

• Rear brake pulsation or grabbing on your Pontiac Bonneville during stops, out-of-round drum bore
• Grinding or scraping from the Bonneville rear axle with the parking brake fully released
• Bonneville drum inner surface scored or worn to maximum allowable diameter on inspection
• Friction lining at or below 1.5mm on your Pontiac Bonneville visible during drum removal
• Parking brake on your Bonneville requiring excessive travel before holding on a slope
• Pontiac Bonneville pulling to one side under braking, asymmetric drum or shoe condition

Why GeoBrakes for the Pontiac Bonneville Brake Drum Kit

Drum and shoe arc radius must match exactly for correct contact geometry on the Pontiac Bonneville. An incorrect drum diameter or wrong-spec shoe lining for the Bonneville produces immediate uneven wear and noise. Every kit in the GeoBrakes catalogue is assembled for the Pontiac Bonneville, drum diameter, shoe arc, and hardware spring rates all confirmed as a matched set specific to the Bonneville.

Frequently Asked Questions - Pontiac Bonneville Brake Drum Kits

How do I know if I need a basic or full-service kit for my Pontiac Bonneville?

A basic kit for the Pontiac Bonneville is appropriate when the wheel cylinders have been recently replaced and show no signs of leaking. A full-service kit is the stronger choice during a high-mileage Bonneville overhaul, particularly on American Pontiac Bonneville vehicles with significant winter salt exposure.

Should I replace drum kits on both rear wheels of my Pontiac Bonneville at the same time?

Yes. Always replace drum brake components on the Pontiac Bonneville as an axle set, both left and right rear, to maintain balanced braking force. Drums and shoes at different wear stages on the Bonneville create uneven rear braking that pulls the vehicle to one side.

Can I install a brake drum kit on my Pontiac Bonneville myself?

Rear drum brake service on the Pontiac Bonneville is a moderately advanced DIY task. It requires removing the drum, dismantling the shoe assembly on the Bonneville, correctly routing return springs, and adjusting shoes to the correct drum clearance. A service manual specific to the Pontiac Bonneville is essential.
