A braking system designed to be an integral part of a shopping cart. The braking system consists of a hand-operated brake that is gravity actuated and normal ly engaged. The user disengages the braking system to move the shopping cart, preferably by pushing a primary handle of the cart. The braking system is also disengaged when the shopping cart is nested with other shopping carts to allow multiple carts to be moved without the brakes being engaged. The mechanical link from the handle to the brake is enclosed within the frame to reduce potential damage to the mechanism. The mechanical link consists of a hand-activated handle that is pushed down to disengage the brake, and when the handle is not depressed, th e handle raises by gravity and applies the brake.
