摘要： The invention provides an electro-mechanical brake system which can keep a stop state even if a malfunction is generated in a parking brake, and an electro-mechanical brake apparatus used for the electro-mechanical brake system. An electro-mechanical brake actuator (6) presses a brake pad to a disc rotor (7) so as to independently brake a braking force of each of wheels. A parking brake is constituted by a pawl portion (10a) attached to a motor (10) of a motor driving the electro-mechanical actuator (6) and a latch (21a). A main controller (3) detects a failure of the parking brake on the basis of a motor displacement at a time of reducing a motor current, and increases the pressing force in the remaining normal parking brake in the case that the parking brake failure in one wheel or more is detected.
