BRAKE SERVICE PROCEDURES FOR 2003 BMW 330CI AUTOMOBILES
Power Brake Units -> Description -> Hydraulic Booster System -> Vacuum Booster System
Vehicle: 2003 BMW 330CI 3.0 L6 GAS
Hydraulic Booster System
The hydraulic system incorporates a power flow regulator which diverts a small flow of fluid from the power steering operating circuit for the power assisted brake system, Fig. . 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 permit m...
