Power Brake Units - BENDIX HYDROBOOST: Description
NOTE:
The Bendix Hydro-Boost is standard on some models and optional on others. See the BRAKE APPLICATION tables at the beginning of this section.
System utilizes power steering pump fluid pressure to operate booster. Assembly contains an open center spool valve which controls pump pressure magnitude during braking, a lever mechanism to control position of valve, and a boost piston to provide force necessary to operate master cylinder. Unit also has a reserve system which stores sufficient fluid under pressure to provide at least two braking applications in case fluid flow from power steering pump is not available. Brakes can also be applied manually if reserve system is depleted.
