ABSTRACT:
An anti-lock brake control system for an automobile is provided with a master cylinder, a main fluid passage communicating between the master cylinder and at least one wheel brake, a recirculating passage branched off from the main fluid passage for recirculating a fluid medium back to the main fluid passage, a pump disposed in the recirculating passage for recirculating the fluid medium, a pressure regulator for reducing or increasing the brake pressure of the wheel brake and an anti-lock modulator for changing the area of the main fluid passage. The modulator is provided with a housing having a fluid chamber, a first port communicating with the master cylinder and a second port communicating with the pump, and with a movable element vertically movably accommodated in the fluid chamber. The movable element is normally located at a lower position in the fluid chamber by the gravity and moved upwards by the flow of the fluid medium discharged from the pump. The modulator is so constructed as to reduce the area of the main fluid passage when the movable element is moved upwards.
