The present disclosure relates to a drum brake. The drum brake includes a bolt screw being rotated in conjunction with drive of a first motor, a nut piston being combined by a bolt-nut fastening with a circumference of the bolt screw and being moved toward a direction in which the nut piston presses against a shoe, in conjunction of the rotation of the bolt screw, and a press nut being combined by the bolt-nut fastening with a circumference of the nut piston, being moved toward an axial direction in conjunction with drive of a second motor, being brought into contact with the bolt screw, and thus preventing the nut piston from being pushed due to a reaction force of the shoe.
