とを特徴とするアンチスキツドブレーキ装置。 A hydraulic brake system comprising two independent hydraulic piping connecting the braking cylinders of one front and rear wheel among the braking cylinders of the wheels, and formed so that the hydraulic pressure of the master cylinder is supplied to each of the hydraulic pipings, respectively. In the anti-skid brake device installed in A select low valve is provided in between to reduce the hydraulic pressure difference between both hydraulic pipes, an operation detection means is provided in the select low valve to detect the operating status of the hydraulic pressure difference reducing operation, and an anti-skid signal from the controller is configured to detect the anti-skid signal from the controller. and an AND circuit having one input and an inverted signal of the stroke signal from the motion detection means as a second input, and generating a fail-safe signal in accordance with the output logic level of the AND circuit. Anti-skid brake device.
