1. An electric brake system comprising:
a main device configured to provide a first hydraulic pressure to a plurality of wheel cylinders respectively installed on a plurality of wheels, based on a position of a brake pedal; and
an auxiliary device configured to provide a second hydraulic pressure to first and second wheel cylinders respectively installed on first and second wheels only among the plurality of wheels based on the position of the brake pedal in a state in which the main device does not generate the first hydraulic pressure,
wherein the auxiliary device is configured to receive power from a power network different from that of the main device, and the auxiliary device is configured to control first and second parking brakes respectively installed on third and fourth wheels, which cannot receive the second hydraulic pressure from the auxiliary device, among the plurality of wheels.
