PROBLEM TO BE SOLVED: To perform proper brake control, by highly accurately detecting a rapid rise of a road surface friction coefficient (μjump condition) in each wheel without additionally providing a particular sensor, and surely suppressing insufficiency of brake force atμjump time. SOLUTION: This device comprises a wheel speed detection means 6a detecting a wheel speed Vw, brake pressure adjusting means 4a arranged corresponding to each wheel, and a controller 10A controlling a braking amount of a brake driven by the brake pressure adjusting means. The controller includes a means 14 calculating a brake parameter based on the wheel speed, control amount arithmetic means 15 outputting a drive command DA for decreasing/ increasing, based on the brake parameter, a brake pressure applied to each wheel from the brake pressure adjusting means, means 16 deciding aμjump condition, and a means 17 changing the brake pressure into an increasing direction atμjump time.
