Claim 0:
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,
a connection hose to connect the master cylinder reservoir and the hydraulic block reservoir; and
wherein:
the master cylinder reservoir includes a plurality of reservoir chambers divided by partitions,
one of the plurality of reservoir chambers is connected to a first master chamber of the master cylinder, another is connected to a second master chamber of the master cylinder,
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.
