Abstract
An electric brake system is disclosed. The electric brake system includes a hydraulic pressure supply device configured to generate hydraulic pressure using a piston which is operated by means of an electrical signal that is output corresponding to displacement of a brake pedal, and including a first pressure chamber provided at one side of the piston movably accommodated inside a cylinder block and connected to one or more wheel cylinders, and a second pressure chamber provided at the other side of the piston and connected to the one or more wheel cylinders, a first hydraulic flow path configured to communicate with the first pressure chamber, a second hydraulic flow path configured to branch from the first hydraulic flow path, a third hydraulic flow path configured to branch from the first hydraulic flow path, a fourth hydraulic flow path configured to communicate with the second pressure chamber and connected to the third hydraulic flow path, a fifth hydraulic flow path configured to communicate the second hydraulic flow path with the third hydraulic flow path, a first hydraulic circuit including first and second branching flow paths which branch from the second hydraulic flow path and are connected to two wheel cylinders, respectively, and a second hydraulic circuit including third and fourth branching flow paths which branch from the third hydraulic flow path and are connected to two wheel cylinders, respectively.
