ABSTRACT:
A brake system that provides a good pedal feel, that assists stepping force of a driver by a small motor, and that can control braking force of wheels individually. The brake system comprises a first actuator (5) for increasing a liquid pressure in a master cylinder (2) by driving torque of a motor (51), and a second actuator (6) capable of driving a brake generating mechanism (3) without transmitting power to the master cylinder (2), wherein the actuators (5, 6) to be driven are switched depending on the operation of a brake pedal (1). The first and second actuators (5, 6) are connected to hydraulic piping (4f,4r), and a pressurized oil is supplied to the brake generating mechanism (3) through hydraulic valve means (63f,63r, . . .65rr).
