Our Hydropower hydraulic brake assist power booster fits 1955-57 Chevy Belair and generates up to 1800psi of line pressure to the brake calipers. It is fitted with a 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 55-57 Chevy Belair 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.

Asurion protection - I approve
Asurion was able to keep me informed from the start of the return process to its conclusion. They were very courteous and understanding. They resolved the refund swiftly and I had no trouble at all redeeming.

Worth ordering
This seems like you get more at once than buying from the eufy store and I use it pretty frequently with 2 dogs and a son in the house. This keeps me from having to order so often.
