ABSTRACT:
An improved braking system includes a valving arrangement which permits reduction of deadband regardless of a randomly selectable piston home position or permits adjustment of the deadband. The system includes a fluid reservoir, a piston located in a cylinder including a reservoir port, a first fluid channel connecting the reservoir to the reservoir port, a brake actuator, and a second fluid channel connecting the cylinder to the brake actuator. The piston is moveable within the cylinder to produce fluid flow within the first channel. A first valve is disposed between the reservoir and the cylinder to prevent fluid flow from the cylinder to the reservoir when the piston is moved to pressurize fluid in the second fluid channel.
