とを特徴とするアンチスキツドブレーキ装置。 A hydraulic brake is provided with two sets of independent hydraulic piping connecting the braking cylinders of one front and rear wheel among the braking cylinders of each wheel, and configured such that each of the hydraulic pipings is supplied with hydraulic pressure from a master cylinder, respectively. In the anti-skid brake device attached to the system, a modulator is installed in the middle of one of the two sets of hydraulic piping and performs anti-skid operation in response to a signal from the controller, and the two sets of hydraulic piping A select low valve is provided between the two hydraulic pipes to reduce the hydraulic pressure difference between the two hydraulic pipes, an operation detection means is provided in the select low valve and detects the operating status of the hydraulic pressure difference reducing operation, and an anti-skid signal from the controller is provided. and an AND circuit having an inverted signal as a first input and a 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. Features an anti-skid brake device.
