Description: This listing is for a Hydro boost hydraulic brake assist power booster and Hose Kit that fits 1963-66 Chevy and GMC trucks. It generates up to 1800psi of line pressure to the brake calipers. It is fitted with a Wilwood master cylinder and Black 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 black firewall brackets are correct for 63-66 GM truck applications. The average power steering pump puts out from 800psi to 1400psi line pressure this 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.
