Claim 18:
19. The modular portable storage container system of claim 18 wherein the brake mechanism further comprises:
a brake pedal;
a brake pivot shaft, the brake pedal fixedly mounted to the brake pivot shaft via a receiving aperture, each of the brake pivot shaft and the receiving aperture having corresponding keyed features preventing rotation of the brake pivot shaft relative to the brake pedal, the brake pivot shaft rotatably disposed through a portion of the first container section and the second container section;
a sleeve rigidly affixed to each of the first container section and the second container section, the sleeve being vertically oriented, offset, and orthogonal to the brake pivot shaft;
an actuator rod slidably retained within the sleeve, the actuator rod extending from a rod pin to a brake pad, the rod pin slidably and rotatably disposed within an aperture in the brake pedal, and the brake pad extending in a downward direction; and
an aperture formed through the sleeve and facing inwardly towards the first container section and the second container section;
a detent formed in the actuator rod and selectively alignable with the aperture in the sleeve; and
a spring-loaded retainer having a rod-shaped element and a retainer spring, the spring-loaded retainer fixedly positioned on each of the first container section and the second container section and extending horizontally towards and passing through the aperture to selectively engage with the detent, wherein the retainer spring biases the rod-shaped element towards the aperture in the sleeve so that when the brake pedal is in the engaged position, the rod-shaped element engages with the detent and prevents vertical movement of the actuator rod within the sleeve,
wherein the brake pedal is selectively actuatable between an engaged position and a disengaged position, wherein in the engaged position, the brake pedal rotates about the brake pivot shaft such that the actuator rod moves downward through the sleeve and the brake pad fixedly engages with the floor on which each of the first container section and the second container section rests.
