Abstract
A pressure control solenoid based vehicle braking system utilizes intensifiers to permit the hydraulic control components to operate at lower pressures. A method of selectively locking the intensifiers in position is provided. Unique pressure regulators provide predictable control of load pressure and are isolated in the system by a combination of enable valves and the locking method.
