The present invention discloses an electronic hydraulic brake system, which may include: a main master cylinder driven by a motor in response to control of an electronic control unit (ECU), and supplying oil pressure to wheel cylinders; and a backup master cylinder forming a reaction force on a brake pedal in response to pressure of the brake pedal. When power of the ECU is cut off, the backup master cylinder may supply oil pressure to the main master cylinder. Thus, a manual bleeding operation may be performed even in a state where power is cut off for an after service of the vehicle, and the number and size of parts may be decreased to reduce the weight and manufacturing cost of the vehicle.
