Claim 14:
15. The military vehicle of claim 1, further comprising a brake system including:
a brake configured to facilitate braking a tractive element;
a brake housing defining an inner volume;
a piston separating the inner volume into a first chamber and a second chamber;
a rod extending through an end of the brake housing and coupled to the piston, the rod positioned to selectively engage with the brake to inhibit movement of the tractive element;
a resilient member positioned within the inner volume and configured to generate a brake biasing force against the piston such that the rod is biased into engagement with the brake;
an air-to-hydraulic intensifier coupled to the brake housing, the air-to-hydraulic intensifier configured to receive a supply of air and provide a hydraulic fluid to the brake housing based on the supply of air to overcome the brake biasing force to disengage the rod from the brake to permit movement of the tractive element;
a valve positioned between the air-to-hydraulic intensifier and the brake housing; and
a hydraulic reservoir fluidly coupled to the valve and the air-to-hydraulic intensifier;
wherein 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 housing, and a valve gate that is repositionable between a first position and a second position, the first position coupling the first port to the third port to fluidly couple the air-to-hydraulic intensifier to the brake housing, the second position coupling the second port to the third port to fluidly couple the hydraulic reservoir to the brake housing.
