摘要： A method for detecting fluid leakage from a pressure-decrease valve in a hydraulic brake system having an ABS device including: a shutoff valve for shutting off supply of a working fluid from a fluid-pressure supply source to a brake device provided for a wheel; the pressure-decrease valve for discharging the working fluid from the brake device; a reservoir for storing the working fluid discharged from the pressure-decrease valve; and a return pump for returning the working fluid stored in the reservoir to a portion between the shutoff valve and the fluid-pressure supply source, the method including the steps of: activating the return pump in a state in which the hydraulic brake system is not in ABS operation, and detecting the fluid leakage from the pressure-decrease valve based on a variation in a pressure of the working fluid in the fluid-pressure supply source caused when the return pump is activated.

摘要： A hydraulic braking system includes: a master cylinder including a pressurizing piston, a rearward chamber, and a pressure chamber; and a rearward-hydraulic-pressure controller connected to the rearward chamber and including a pressure increase valve and a regulator for controlling a hydraulic pressure in an output chamber. An air detector includes: an upstream detector, including the rearward-hydraulic-pressure controller, for detecting presence or absence of air in an upstream portion based on a relationship between the hydraulic pressure in the output chamber and an open time of the pressure increase valve; and a downstream detector for detecting presence or absence of air in a downstream portion based on a relationship between a stroke of the pressurizing piston and the hydraulic pressure in the output chamber. The downstream portion includes a portion located downstream of the pressure chamber of the master cylinder.
