An automatic braking apparatus for inclusion with a user-propelled grocery cart, luggage cart or the like is provided which automatically brakes at least one of the cart wheels when not in use and which allows easy, convenient, and automatic release of the braking mechanism by the user during operation. The preferred apparatus includes a braking mechanism shiftable between a braked position for braking at least one cart wheel and a released position for releasing the wheel and including a spring for biasing the mechanism toward the braked position, an intermediate structure pivotally coupled adjacent the cart handle and interconnected with the brake mechanism; and an operating member pivotally coupled with the handle and intercoupled with the intermediate structure including a handle portion for grasping by the cart user. In operation, the user grasps the handle portion and pushes generally forwardly which rotates the operative member, the intermediate structure, and the braking mechanism to the released position; the spring automatically shifts the apparatus components to the braked position when the handle portion is released.
