Hydraulic Brake Booster: Description and Operation
Brake Booster - Hydro-Boost(R)
The Hydro-Boost(R) power brake actuation system consists of the following components:
^
Hydro-Boost(R) brake booster
^
Power steering pump
^
Power steering lines
The Hydro-Boost(R) brake booster is a hydraulically operated brake booster powered by the power steering pump. The power steering pump provides
the fluid pressure to operate both the power brake booster and the power steering gear.
A Hydro-Boost(R) reserve system (accumulator) stores sufficient fluid under pressure to provide at least 2 power assisted brake applications in the
event the power steering pump fluid flow is interrupted.
The brakes can also be applied manually if the reserve system is depleted.
