A shopping cart braking assembly includes a leg structure extending downwardly from the a portion of a shopping cart frame. A rear wheel assembly is pivotally attached to the shopping cart adjacent to the leg structure. The rear wheel assembly is selectively movable between a first position wherein wheels of the rear wheel assembly are in contact with the ground to enable the shopping cart to roll, and a second position wherein the wheels are elevated and the leg structure is in contact with the ground to support the shopping cart in a stationary position. A foot bar and spring may be associated with the rear wheel assembly to facilitate pivoting the rear wheel assembly into the stationary and mobile positions.
