PURPOSE:To make improvements in braking efficiency while securing stability as well as to aim at the promotion of lightweightiness with the number of control channels reduced to only one, by weakening the extent of braking force in both symmetrical wheels simultaneously when a wheel in a side higher in wheel speed is about to come into a state of being locked. CONSTITUTION:An antilock controller 9 inputs each signal out of respective wheel speed detector 10l, 10r, 11l and 11r, while a rear-wheel control part 9a decompresses each of brakes Bfl, Bfr individually via modulators Mfl, Mfr when front wheels are about to lock. On the other hand, a rear-wheel driving control part 9b operates these modulators Mrl, Mrr for antilock simultaneously when rear wheels, corresponding to wheel speed of a higher side out of wheel speeds of both rear wheels Wrl, Wrr connected to each other via a rear differential gear, is likely to enter their lock state. Thus, improvement in braking efficiency is promoted as securing stability, and the number of control channels is reduced to only one whereby the promotion of lightweightiness is enabled and, what is more, required space is reduced.
