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 or Wilwood master cylinder and a Black Out 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 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.

Stopped charging one month later.
Color: 2-Speed Silver, Size: Rechargeable
It was great even though it grinds very coarse. It can be adjusted but the finer is still too coarse but that was not a big deal. It has now stopped taking charge at the base and there’s no other way to charge it… since the return window closed, to the trash it goes

Works Very Well
Color: 2-Speed Silver, Size: Rechargeable
At first salt spilled from bottom and top was loose. I then realized there was an adjustment on bottom that took care of that issue and if I put top on until it clicked, it locked. They work very nicely and I would recommend them.

Convenient set with charging stand and light
Color: 2-Speed Silver, Size: Rechargeable
Recommend for anyone who cooks and wants fresh seasoning with less hassle. The built-in light on the bottom was a pleasant surprise and ends up being genuinely useful. It helps you see exactly where the seasoning is going and how much you’re dispensing, especially when you’re cooking in the evening or working over darker foods. That small detail makes the set feel more practical than a basic grinder.
