Electronic brake system

An electronic brake system comprises: a first block in which arranged is a mechanical part that is linked with a brake pedal to be mechanically operated; a second block in which arranged is an electronic part that is electronically operated and controlled by an electronic control unit; an emergency module which operates when the electronic part is inoperative, and secondarily provides a fluid pressure; and connection lines which hydraulically connect the first block and the second block and the emergency module, wherein the first block and the second block and the emergency module may be installed at positions spaced from each other in a vehicle, and thus the mountability of the brake system and the degree of freedom in designing a vehicle may be improved.
