ABSTRACT:
A short master cylinder uses solenoids to control the master cylinder compensating and bypass functions. The pressurizing pistons each use only one seal. There is a unitary primary piston and booster output push rod. The booster power piston return spring returns the primary piston and, through a lost motion interconnection, the secondary piston, omitting the secondary piston spring. Brake pedal travel and pressure sensors control the solenoid valves, reducing lost brake pedal travel.
