A power-operated caster brake mechanism includes a driving device having a driving motor; a linking mechanism having a shifting member connected to a moving bar of the driving motor, and two rotating members connected to two ends of the shifting member; a caster connected to each rotating member and including a wheel and a brake and direction-lock mechanism, the latter including a brake block located in a wheel support, and a pin connected at an end to the brake block and another end to the rotating member; and a mechanical switch connected to the moving bar. When the driving motor shifts the shifting member, the rotating members rotate the brake blocks to different positions, bringing the casters to a braked, a direction-locked, or a freely swiveling state. In case the driving motor is failed, the casters can still be set to a desired operating state with the mechanical switch.
