Hand-operated brakes caster system is easy to use, compact, lightweight, low-cost. A fork supports a rotating wheel via an axle. A bag mounted base supports the swinging fork. A hollow swing shaft mounts on a base bearing. A force transmitting wire is pulled by a rotation knob in a controller away from the wheel. Opening direction force is applied by a spring to the wire in the opening direction. Therefore, if the knob is rotated by an angle not smaller than a predetermined value, reverse rotational moment is applied, locking the rotation knob. Force transmitted to a lever via the wire is magnified by the action of the lever, and the resulting force pushes a brake pin located inside the fork swing shaft. The brake pin abuts the tire resulting in frictional resistance preventing rotation of the wheel.
