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 provided between the two hydraulic pipes to reduce the hydraulic pressure difference between the two hydraulic pipes; an operation detection means provided in the select low valve for detecting the operating status of the hydraulic pressure difference reducing operation and providing feedback to the controller;
An anti-skid brake device comprising means for determining an abnormality and generating a fail-safe signal in response to input of an anti-skid signal from the controller and input of a stroke signal from the motion detection means.
