PROBLEM TO BE SOLVED: To provide a brake control device capable of checking an operating state of a motor drive circuit before abnormality is generated in an ECU. SOLUTION: In the brake control device, a CPU 222 and an input/output IC 224 control the drive of a motor 632 to drive a pump. A plurality of motor drive circuits each output a drive signal of the motor 632, and are arranged in parallel. When an adjusting circuit 232 receives a signal indicating the abnormality of the CPU 222 or the input/output IC 224, out of the drive signal of plurality of motor drive circuit, each one of the drive signal is selectively output to supply the drive signal to the motor 632. The CPU 222 and the input/output IC 224 outputs the signal indicating the abnormality of the CPU 222 and the input/output IC 224, and checks the operating state of the motor drive circuit based on the output of the motor drive circuit received from the adjusting circuit 232.
