Abstract

A military vehicle includes a brake positioned 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 where the rod is 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 biasing force against the piston such that the rod is biased into engagement with the brake, and an air-to-hydraulic intensifier coupled to the brake housing. The air-to-hydraulic intensifier is 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 biasing force to disengage the rod from the brake to permit movement of the tractive element.
