Abstract: A shopping cart is generally a wire framed cage made of a specific gauge of metal that is mounted on four wheels. This invention deals with the use of a braking system to keep shopping carts from rolling away, for example: when a customer pushing their goods in a shopping cart stops on an incline to unload their goods into a vehicle the shopping cart must be held or propped against an object to restrict its movement or otherwise the cart will roll down the hill. This system will stop the shopping cart when the foot activated braking wedge is pressed into the wheel housing, by using the sole part of the shoe. The wheel will not move unless the braking wedge is released from its locking position by pulling upward on the braking wedge extension bar with the toe part of the shoe. This wedge is true to its shape and is applied to the wheel to stop the rotation of the wheel. The wedge takes up the space between the top of the wheel and the bottom of the housing, thus impeding the rotation of the wheel.
