Manual Extract F150 BRAKE BOOSTER

Vehicles are equipped with a vacuum booster. Vehicles may use either a single or dual-diaphragm vacuum booster. The single and dual-diaphragm (tandem) vacuum boosters are self-contained, vacuum power brake units. Booster assists in actuating master cylinder push rod.
Booster contains either a single or dual vacuum-suspended diaphragm which uses engine manifold vacuum or atmospheric pressure for power. Diesel models use a belt-driven vacuum pump to provide vacuum for booster actuation.

A mechanically-operated booster check valve controls power brake application and release in relation to foot pressure applied to check valve operating rod. Booster check valve is the only serviceable component of brake booster assembly.

An equalizer valve links 2 chambers of brake booster. When valve opens, vacuum in chambers can equalize.
When it closes, chambers are separated. A vacuum bleed valve functions to reduce amount of vacuum in chamber “B” when boost is required. See Fig. 1 .
F Super Duty uses a Hydro-Boost system. Hydro-Boost is hydraulically operated by power steering pump and provides a variable power assist regulated by brake pedal pressure. Hydro-Boost has a reserve system (compressed gas accumulator) which stores enough fluid under pressure to provide at least 2 power-assisted brake applications if power steering pump fluid flow stops. Brakes can also be operated manually if reserve system is lost.
