Bendix Hydro-Boost

System utilizes power steering pump fluid pressure to operate booster. The assembly contains an open-center spool valve which controls pump pressure during braking. Also a lever mechanism is used to control the position of the valve and a boost piston to operate master cylinder.

The unit also has a reserve system which stores sufficient fluid under pressure to provide at least 2 braking applications. Brakes can be applied manually if reserve system is depleted.
