PURPOSE:To prevent the wheel locking and to prevent the sliding by providing an electromagnetic exchange valve in a brake piping to the rear wheel and operating such that the rear wheel braking force is reduced in accordance to the abrupt drop of the wheel speed. CONSTITUTION:An electromagnetic exchange valve 9 is provided in the brake piping to the rear wheels 5, 6 to function such that the braking liquid is returned to the reservoir of a master cylinder 2. Said valve 9 is actuated when the wheel speed is dropped abruptly. When the wheel is locked by the excessive braking force, the rear wheel braking force is reduced to lengthen the braking distance but since the rear wheel locking is released the sliding is prevented. |
