Speedmaster 8" Universal Dual Diaphragm Brake Booster PCE165.1004.01 Zinc

The Speedmaster 8" Universal Dual Diaphragm Brake Booster (PCE165.1004.01) is a zinc-finished brake booster engineered to amplify hydraulic pressure and reduce brake pedal effort in vehicles equipped with power-assisted braking systems. Designed as a universal component, this dual diaphragm booster delivers consistent stopping power by increasing the force applied to the master cylinder, making it ideal for street rods, customs, and restoration projects.

This brake booster offers reliable performance across a wide range of vehicles and brake system configurations. The dual diaphragm design provides responsive braking feel while the durable zinc finish resists corrosion in underbody environments. Common applications include hot rods, classic muscle cars, custom builds, and retrofit installations where factory brake boosters require replacement or upgrading.
