ABSTRACT OF THE DISCLOSURE Disclosed is a brake control system for an automotive vehicle for controlling application and release of brake pressure in order to prevent the vehicle from skidding. The system has a means for determining friction coefficient based on the wheel acceleration speed, wheel load and brake torque, a means for detecting a peak of the friction coefficient, a means for determining wheel r.p.m., a means for determining target wheel r.p.m. based on the wheel r.p.m. and being operative responsive to detecting of the peak of friction coefficient, and a control means for controlling applying and releasing of pressure fluid to wheel cylinders for skid controlling the wheel deceleration ratio. The target wheel r.p.m. determines ratio of decele- ration of wheel r.p.m. based on the difference of wheel r.p.m. between the time detecting the peak of friction coefficient and the time detecting immediate preceding peak and the length of period between detecting of the peaks and thereby determining the target wheel r.p.m. by subtracting a deceleration value obtained based on the determined ratio of deceleration from the wheel r.p.m. determined at the time of detecting of the peak of friction coefficient.
