The electronic brake system (1) disclosed includes a hydraulic-pressure supply device (100) and a hydraulic-pressure control unit (200). The hydraulic-pressure supply device (100) operates a hydraulic piston (114) using an electric signal corresponding to a displacement of a brake pedal (10), and thus generates hydraulic pressure. The hydraulic-pressure control unit (200) controls hydraulic pressure of a pressure medium supplied to individual wheel cylinders (40). The disclosed electronic brake system (1) comprises in the hydraulic-pressure control unit (200) six, preferably seven, particular hydraulic passages (211-216,417) which preferably comprise a plurality of valves (231-237,332,431-436,534-537,633,738,838). Using several different preferred embodiments of the disclosed electronic braking system (1), amongst others, a normal operation mode, an abnormal operation mode, a regenerative braking mode and an inspection mode using said valves (231-237,332,,431-436,534-537,633,738,838) are disclosed.
