Abstract: Embodiments of a wheel and a brake mechanism for use with a non-motorized cart such as a shopping cart are disclosed. In some embodiments the wheel has a hub having a plurality of first engagement features, and the brake mechanism includes at least one second engagement feature that can be moved between an unactuated position and an actuated position. In the unactuated position, the second engagement feature does not engage any of the plurality of first engagement features on the hub, and in the actuated position, the second engagement feature operatively engages at least one of the first engagement features in order to provide a braking force that locks the wheel. A magnetically-activated trigger maintains the second engagement feature in the unactuated position. In response to a triggering magnetic field, the trigger is released and allows the second engagement feature to move from the unactuated position to the actuated position.
