1973-87 Chevy, GMC Truck Hydropower Brake Boost Kit HYDRO BOOST ROUTING AND FITTING SIZES
Part #:HB2-T7387
Brakes Type


Our Hydropower hydraulic brake assist power booster fits 1973-87 Chevy and GMC trucks and generates up to 1800psi of line pressure to the brake calipers. It is fitted with a POL master cylinder and 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 73-87 GM truck applications.
The average power steering pump puts out from 800psi to 1400psi line pressure. The Hydropower unit 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.

  • Hydraulic brake assist power booster
  • 1.00" bore POL master cylinder
  • POL proportioning valve, bracket and lines (works with front disc & rear disc or drum brakes)
