Power Brake Booster

Shop New OEM power brake boosters for GM vehicles. Our factory-original vacuum and electric brake boost assemblies are sourced from GM surplus — the correct booster diameter, pushrod travel, and vacuum port configuration for your braking system.

The brake booster multiplies your pedal force to generate the hydraulic pressure needed for effective braking. Booster diameter and vacuum reserve volume determine pedal feel and stopping power. An OEM booster provides the factory-specified assist ratio that your vehicle's master cylinder and caliper sizing were designed around.

Brake booster replacement requires brake system bleeding and pedal adjustment. Verify part numbers against your vehicle's brake system configuration before ordering.
