Our Hydro boost hydraulic brake assist power booster fits 1955-59 2nd series Chevy and GMC trucks and generates up to 1800psi of line pressure to the brake calipers. It is fitted with a Wilwood master cylinder and adjustable proportioning valve. This kit is powered by hydraulic line pressure from the power steering pump. Firewall and valve cover clearance is equivalent to a 7" diameter vacuum booster. The firewall brackets are correct for 55-59 GM truck applications.

The average power steering pump puts out from 800psi to 1400psi line pressure. The Hydro-Boost® uses this to convert to pressure to apply against the master cylinder. This greatly improves stopping performance and driver feedback. These hydraulic power boosters can be easily installed on an existing vacuum booster vehicle or used to convert a manual brake setup to power with ordinary hand tools and average mechanical ability.

Fits: 1955 1956 1957 1958 1959 Chevy GMC Apache 2nd series 3100 truck.
