Abstract: A shopping cart braking device, for use in conjunction with an existing shopping cart, for selectively immobilizing the shopping cart upon a support surface. The braking device comprises a substantially U-shaped tube having a first end, a second end, and a horizontal centrally located connecting portion extending concentrically through a brake pad. The first and second ends of the braking device are hingeably attached to the front crossbar of the shopping cart, in proximity to the front wheels of the shopping cart. When the braking device is in the unbraked position, the braking device has been raised by a foot of the user, and the movement of the shopping cart is unimpeded. When the braking device is in the braked position, the braking device has been lowered by the foot of the user, the brake pad is wedged under the front wheels of the shopping cart, and the shopping cart is immobilized.
