Abstract
Disclosed is an antilock braking device including a first braking hydraulic adjusting member actuated so as to restrain braking oil pressure of wheel cylinders individually corresponding to left and right front wheels in response to antilock braking oil pressure for front wheels; a second braking hydraulic adjusting member actuated so as to restrain braking oil pressure of wheel cylinders individually corresponding to left and right rear wheels in response to antilock braking oil pressure for rear wheels; an antilock control system having a reservoir and a pump for pressurizing control oil from said reservoir to generate said antilock control oil pressure; and a tandem type master cylinder having a pair of output ports independent of each other connected to said both braking hydraulic adjusting members to generate braking oil pressure of each of said wheel cylinders, characterized in that a proportional reducing valve is interposed between both braking hydraulic adjusting members in order to supply braking oil pressure from the first or second braking hydraulic adjusting member corresponding to the front wheel or rear wheel subject to the larger supporting load to the second or first braking hydraulic adjusting member corresponding to the rear wheel or front wheel subject to the smaller supporting load.
