Abstract
A wheel slip control system for independently executing an anti-skid control and a traction control. The system includes a microcomputer, a first capacity control valve for anti-skid control, a selector valve, and a second capacity control valve for traction control. These values are connected in series between a master cylinder and a break cylinder. Such valves prevent brake fluid from over-charging a reservoir even in the course of switching from anti-skid control to traction control or vice versa, so that the brake pressure is properly reduced without consideration of capacity of the reservoir.
