Abstract

A brake system includes a brake actuator configured to engage a brake to limit movement of a tractive element, an air-to-hydraulic intensifier coupled to the brake actuator where the air-to-hydraulic intensifier is configured to receive a supply of air and provide a hydraulic fluid to the brake actuator based on the supply of air to overcome a brake biasing force of the brake actuator to disengage the brake actuator from the brake to permit movement of the tractive element, a hydraulic reservoir coupled to the air-to-hydraulic intensifier, and a valve. The valve includes a first port fluidly coupled to the air-to-hydraulic intensifier, a second port fluidly coupled to the hydraulic reservoir, a third port fluidly coupled to the brake actuator, and a valve gate that is repositionable between a first position that couples the first port to the third port and a second position that couples the second port to the third port.
