    摘要： Disclosed is an electronic brake system. The electronic brake system according to the present embodiment comprises: a first block in which a mechanical part that is mechanically operated and linked 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; and a connection line which hydraulically connects the first block and the second block. The first block and the second block 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 freedom in designing the vehicle can be improved.
