a master cylinder(1) generating the hydraulic pressure to receive the force from a brake pedal; a flow control valve(3) discharging a fluid transmitted from the master cylinder(1); a brake braking a wheel with a pressure transmitted from the flow control valve(3); a solenoid valve(4) reducing the hydraulic pressure of the brake when the wheel slides due to excessive hydraulic pressure of the brake; an expander chamber(6) receiving the fluid from the solenoid valve(4); a piston pump transmitting the fluid to the flow control valve(3) to pump the fluid transmitted from the solenoid valve(4) and the expander chamer(6); motors(5)(27) driving the piston pump(5); a first check valve transmitting the brake pressure to the master cylinder when the operation force of the pedal is eliminated; and a second check valve(28a) supplying the fluid to the piston pump(5). The control apparatus prevents accidental spinning due to the difference in the brake forces applied to the right and left wheels.
