PROBLEM TO BE SOLVED: To control not to carry out a one-side braking operation in a dangerous condition. SOLUTION: To the disks 12 and 12 of the rear axles 10a and 10b of the left and the right rear wheels 5 and 5 in a tractor, hydraulic brake outputs 13 and 13 are installed respectively. On the other hand, in a hydraulic circuit 14 to both brake outputs 13 and 13, actuating controller 16a and 16b to detect the actuating operation of the left and the right brake pedals 15 and 15 are provided, and an electromagnetic solenoid type change-over valve 17 to convert to feed the braking force to both brake outputs 13 and 13, even when any side of the left and the right brake pedals 15 and 15 is actuated, through a controller 21, when the inclination of the body and the car speed are larger than the set values, is provided. |
