PROBLEM TO BE SOLVED: To provide only one electronic device constituted into a single body for all the examples of deformation of an anti-lock braking system. SOLUTION: This anti-lock braking system(ABS) for a two axle vehicle is provided with four wheel revolution speed sensors and at least two modulators 8, 18, 19 for adjusting a braking pressure. The modulator 8 is an axle modulator for supplying braking pressure to both wheels together, and the modulators 18, 19 are wheel modulators for supplying braking pressure to respective wheels of the other axle. The axle modulator 8 has two control terminals 28, 29 and one earth terminal. The ABS is controlled by a four channel ABS electronic device 1 having four adjusting channels having four final stages 20 to 23 controlling four modulators at the maximum. Each of the four final stages has one amplifier for an inlet valve EV and one amplifier for an outlet valve AV of the modulator to be connected.
