1. An electronic brake system comprising:
a master cylinder unit including a master cylinder to generate a hydraulic pressure and a master cylinder reservoir coupled to the master cylinder to store oil;
a hydraulic block provided with a hydraulic pressure supply device to generate the hydraulic pressure by a hydraulic piston actuated by an electrical signal outputted in response to a displacement of a brake pedal, and a hydraulic control unit to transmit the hydraulic pressure to wheel cylinders provided in each wheel, and disposed to be separated from the master cylinder unit;
a hydraulic block reservoir to supply oil to the hydraulic block side or store discharged oil, and
a connection hose to connect the master cylinder reservoir and the hydraulic block reservoir;
wherein:
the hydraulic pressure supply device includes a cylinder block in which the hydraulic piston is accommodated, a first pressure chamber provided at one side of the hydraulic piston in the cylinder block to be connected to the wheel cylinder, and a second pressure chamber provided at the other side of the hydraulic piston in the cylinder block to be connected to the wheel cylinder;
the hydraulic block reservoir includes a plurality of hydraulic block reservoir chambers divided by partitions.
