PURPOSE:To make it possible to keep running stability and simultaneously to make it possible to realize an effective anti-lock control by so arranging the constitution that a braking hydraulic pressure for rear wheel brake may be kept in a reduced pressure until the braking operation terminates when some of wheels are going to lock. CONSTITUTION:In the four-wheel driving vehicle, stated in the head line, front axles Afl/Afr and rear axles Arl/Arr are connected to each other through a differential gear Df and Dr respectively, and a viscose clutch 1 where a high viscosity oil is enclosed is interposed on a rear propeller shaft receiving power from a power unit. Further, modulators Mfl, Mfr, Mrl, Mrr having front wheel brakes Bfl, Bfr and rear wheel brakes Brl, Brr connected together by pipes like a letter X and interposed on respective brake pipes are controlled by an anti-lock control device 9. In this case, the control device 9 is so constituted as to be provided with front/rear control parts 9a, 9b which control the device to keep the braking hydraulic pressure of rear wheel brakes in reduced pressure until the braking operation terminates, when some of wheels are going to lock.
