Claim 7:
8. A control device that controls an electric motor of an electric brake comprising a brake mechanism that transmits a thrust generated by driving the electric motor to a piston that moves brake pads pressed against a disc,
the control device being configured to detect an abnormality in the brake mechanism from a thrust of the electric motor and a rotational position of the electric motor in response to a braking command or a position of the piston which are obtained when the electric motor is driven,
wherein, in response to the braking command, the control device drives the electric motor in an applying direction where the brake pads approach the disc, and stops the driving of the electric motor when the thrust is not increased within a predetermined range from a position where the thrust starts increasing in a previous time.
