A brake system operable to inhibit movement of a non-powered transportable cart. The cart has a platform with opposite front and rear ends, at least one pivotal caster wheel adjacent and supporting one of the front or rear ends, and a pair of fixed wheels. The brake system has a brake arm with a brake bar extending laterally therefrom. The brake arm is pivotal between a disengaged position and an engaged position. When in the disengaged position, a gap is defined between the brake bar and the fixed wheels to allow the fixed wheels to rotate freely. When in the engaged position, the brake bar engages the fixed wheels to prevent them from rotating. A brake latch is carried by the platform and has a catch sized to receive the brake arm to releasably maintain the brake arm in its engaged position.
