Power Brake Booster 7in 55-64 GM

The ALLSTAR PERFORMANCE Power Brake Booster 7in 55-64 GM is designed for restoration specialists working on classic Chevrolet and GMC trucks and cars from 1955 through 1964. This single-diaphragm unit is intended to enhance the hydraulic assist of vintage brake systems, which may feel weak or fail over time.

This 7-inch single-diaphragm design integrates into second-generation Chevy platforms, reducing pedal effort while maintaining the feedback that classic car enthusiasts appreciate. It multiplies hydraulic pressure from the master cylinder, aiming to improve braking performance without introducing unwanted sponginess or lag.

Restorers of 1955–1964 Chevrolet Bel Airs, Impalas, Corvettes, C10 trucks, and equivalent GMC models can rely on this booster to enhance their vehicles' braking systems. It is critical to ensure that the engine bay vacuum source is clean and adequate for optimal performance.
