ABSTRACT:
A hydraulic brake slack adjuster disposed between a brake valve and an actuator of a brake mechanism has a first piston exposed to pressurized brake fluid from the valve and a second larger piston connected to the first piston for outputting brake fluid to the brake actuator with the fluid output to the actuator being greater than the volume of input fluid from the valve. This permits a smaller pump to be used while maintaining sufficient brake operation speed.
