H-31 Hydraulic System
The H-31 hydraulic system, Fig. , incorporates a power flow regulator which diverts a small flow of fluid from the power steering operating circuit for the power assisted brake system. It charges the hydraulic reservoir in a high pressure range without impairing the function of power steering. The pressurized hydraulic oil volume is supplied to the booster for the sake of power assistance and is applied by operating the connected standard tandem master cylinder. should the power steering pump fail, the hydraulic reservoir has sufficient reserve pressure to permi...

Anti-lock Brakes -> Description
Vehicle: 1993 BMW 740I 4.0 V8 GAS
The Anti-Lock Brake System (ABS) consists of a control unit, hydraulic unit, speed sensors and wiring harness. Each speed sensor has a gear wheel which runs past the permanently magnetized edge of the speed sensor installed in the wheel hub. The rotary motion of the wheels is recorded by inductive sensors and an electric signal is sent to the electronic control unit.
The electronic control unit is located in a compartment on the right side of the engine compartment. This control unit inputs acceleration, deceleration and slip factors from the electronic speed sensors, which are propo...
