Steering System: Hydro-Boost®
WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, 2008 Ford E450 Super Duty, and 2008 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
The Hydro-Boost® 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.
The Hydro-Boost® 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.
