Abstract: An electrically operated brake device in which braking force differences between electrically operated brakes are reduced to prevent unstable vehicle traveling during braking. Motors 13 of electrically operated brakes are returned to standard positions during the stop of a vehicle and the motor 13 of each of the brakes is driven for a predetermined amount, pressing a brake pad 17 against a disc rotor 18 to produce a braking force. An electric current value of each motor 13 in the above operation is measured and differences between the values are calculated. Electric current of each motor is increased or decreased so that there is no current difference between the motors 13. Based on a drive amount of each motor in this operation, standard positions of the motors are determined and updated. Repeating the above operations reduces braking force differences between the brakes.
