An electronic hydraulic brake system 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.
