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

This is a necessity for anyone that tries a car!!
Size: 20oz 6pk
I haven’t used this yet, but I bought a case to give to my family members. My friend who came outside to a flat tire. It was a Sunday in Utah so there was really no one that could fix it. Walmart told her to get this product. She had to drive home immediately following using this product (300 miles) It has been over two months now and my niece is still driving on that tire. It was a brand new tire that was costly so she decided to just wait and see how long this product will work. Great gift for anyone in the family that drives. This does not work on a blown tire. If you wake up in the morning and your tire is flat, or you get out of class and your tire is flat, just use this product and no calls need to be made.

Great mini-compressor at a great price.
I bought this little guy to inflate tires on my two bikes. It works perfectly. I especially like the set-it & forget-it design. Simply hook it to your valve stem. Once on the stem, it generates a digital reading of your current PSI. Then enter the desired pressure, press start and it starts pressurizing and counts up as they're inflating. Once the target is reached, it shuts-off automatically. What could be easier. BUY IT!

It's good to have it when you need it, rather than need it and don't have it!
Works really well. Great for topping off air pressure. Why spend $3.00 for a couple of PSI's. Good addition to my automotive emergency kit. Quick, easy to use and noise level is minimal.
