Disclosed is an electronic control brake system for vehicles which suppresses residual frictional force generated due to contact between pads and a disc. The electronic control brake system for vehicles includes a master cylinder, wheel brakes, each of which includes a caliper device including a disc and advancing and retracting a pair of pads pressing the disc to exhibit braking force by brake hydraulic pressure transmitted from the master cylinder, plural NO and NC type solenoid valves, low pressure accumulators, pumps and a motor pressurizing a fluid stored in the low pressure accumulators to discharge the fluid to the wheel brakes or the master cylinder, and a section between the plural solenoid valves and the low pressure accumulator is are formed as a closed circuit section, and the pump is driven to move a part of the fluid in the closed circuit section to the outlet of the pump.
