摘要： An electric brake system is disclosed. The electric brake system according to an embodiment of the present invention comprises: a first block in which a mechanical part mechanically operated in connection with a brake pedal is disposed; a second block in which an electronic part electronically operated and controlled by an electronic control unit is disposed; an emergency module which is operated when the operation of the electronic part is disabled to assist in providing hydraulic pressure; and a connection line which hydraulically connects the first block, the second block, and the emergency module to each other. The first block, the second block, and the emergency module can be installed at positions spaced apart from each other in a vehicle, and thus the mountability of the brake system and the degree of design freedom of the vehicle can be improved.
