Abstract
Vehicle hydraulic braking system including a hydraulic pressure source for pressurizing a fluid according to an operation of a brake operating member, so that the pressurized fluid is supplied to at least one wheel brake cylinder for braking at least wheel of the vehicle, a pressure control valve device for regulating the pressure of the fluid to be applied to each wheel brake cylinder, the valve device having a pressure-increasing, pressure-holding and pressure-reducing states, and a reservoir for storing the fluid which has been discharged from each wheel brake cylinder through the pressure control valve device during the operation of the brake operating member, so that the fluid is returned from the reservoir to the hydraulic pressure source after the operation of the brake operating member. The reservoir has a storage capacity smaller than a maximum total amount of the fluid that can be accommodated in all of the at least one wheel brake cylinder during operation of the at least one wheel brake cylinder.
