A method and apparatus for a hand-operated, adjustable, braking or restraining device for effectively restraining the movement of wheeled carts such as shopping carts, flat carts, medical carts, and the like, comprises an engagement lever; an engagement rod; a lever-operated common axle; a pair of operating rods and a pair of eccentrically displaced, sliding, cam-operated braking or restraining mechanisms. The engagement lever has a locking position and a free position and when rotated to its locking position, moves the operating rods thereby engaging the braking or restraining mechanisms. The braking or restraining mechanisms are mounted near the rear wheels of the cart and each is configured to have a cam-operated, eccentrically displaced, sliding brake shoe or pad member which frictionally engages each the rear wheel thereby restraining or preventing the rotation of same.
