An electric hydraulic brake (1) includes: wheel brakes configured to braking force to wheels of a vehicle; a reservoir (110) storing brake oil; a master cylinder (120) connected to the reservoir (110), and operated in conjunction with a main brake motor (122) to generate pressure of the brake oil; a first controller (10) configured to control the main brake motor (122); a hydraulic controller (200) including a pump (231, 232) configured to form pressure of the brake oil in conjunction with an auxiliary brake motor (230), and a hydraulic block (210) configured to selectively transmit the pressure of the brake oil formed in the master cylinder (120) or the pump (231,232) to the wheel brakes; and a second controller (20) configured to control the auxiliary brake motor (230) when the master cylinder (120) or the first controller (10) malfunctions. The hydraulic controller (200) is provided with an auxiliary flow path to transmit the brake oil from the reservoir (110) to the pump (231, 232) directly through the auxiliary flow path.
