Claim 1:
2. The modular portable storage container system of claim 1 wherein the brake mechanism further comprises:
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.
