To provide a brake control device that can facilitate detection of failure state of a brake.

A brake control unit 7 includes an alarm determination circuit 30 that in restricting a brake hub 22 rotating with a rotor 11 to be restricted, determines whether two armatures 20a, 20b are each restricting or releasing the brake hub 22, based on a detected result of each moving position of the two armatures 20a, 20b, the result being detected by a first detector 28a and a second detector 28b which are provided in each of the two armatures 20a, 20b for pressing the brake hub 22.
