Our Hydropower hydraulic brake assist power booster fits 1963-66 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 63-66 GM truck applications.

The average power steering pump puts out from 800psi to 1400psi line pressure. The Hydropower® 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: 1963 1964 1965 1966 Chevy and GMC truck

Preassembled Kit includes:

  • 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)
  • Firewall Mounting brackets

Steering hose hookup kits available in the Suggested Parts below. These are remanufactured Hydropower units. Hydropower® is a registered trademark of the Robert Corporation

An Amazing Addition to My Counter!
Color: Black
At first I did not think I needed this, but after using it for almost a year, I have found out how amazing this product is. It makes the coffee I get much better and lets me pack the grind much more evenly. It is also made of entirely metal, which adds a lot of weight and makes it feel super premium. After using it almost every day for a year now, I still have not needed to replace the needles, yet it came with nine more. All of that value for such a small price makes this great for me and anyone looking to improve their coffee making.

Great little tool
I recently purchased this product after upgrading my grinder. So far it had worked well and the little magnetic holder attaches perfectly to the Breville Barista Express I have. I love that it’s magnetic and keeps the tool out of the way and in a secure spot. Additionally, they throw in a double sided 3M sticky pad for those who do not have a surface where it can magnetize to. Overall great WDT with a great storage solution.
