Our Hydropower hydraulic brake assist power booster fits 1947-53 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 47-53 1st series 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.

Good
Style: Popcorn
I purchased this as a gift. The dog’s on the smaller end, and I wanted to get something not too big so the pup can bite and play with it. These have squeakers inside. It is not sturdy, though. The dog was able to tear one popcorn apart under one hour. I was not amused, but people said that’s just how the toys should work. Little fella loved this right out of the gift bag. The pup seemed happy, hence 5 starts. Made me happy for a bit as well.
