In a vehicular brake control system, a hydraulic braking operation starting from a master cylinder and ending at a wheel cylinder is divided into two systems, i.e., starting from the master cylinder and ending at a stroke absorber (master cylinder system) and starting from a hydraulic generator and ending at the wheel cylinder (wheel cylinder system). Since the master cylinder system is provided with the stroke absorber, a relationship between a depression force imposed on a brake pedal and a brake stroke can be fixed. Since the wheel cylinder system is provided with an output hydraulic control valve controlled so as to produce a braking deceleration rate according to the depression force, another relationship between the depression force and braking deceleration rate can also be fixed.
