Abstract

To provide a power brake having relatively small hysteresis between brake pedal pressure and brake hose pressure and with compact construction, the push rod leading from the brake pedal to the brake master cylinder is divided into an input rod and an output rod. A pressure sensitive element is disposed between the rods and is displacable therewith. The pressure-sensitive element determines the force with which the servo member acts upon the output rod.
