Abstract
The present invention is directed to a hydraulic braking system for an automotive vehicle, wherein a first passage is provided for communicating a master cylinder with first and second wheel cylinders. First and second pressure control devices are disposed in the first passage to control the hydraulic pressure of the brake fluid in the first and second wheel cylinders, respectively. A second passage is provided for communicating the master cylinder with an inlet of an auxiliary pressure source, which introduces the brake fluid from the wheel cylinders, and discharges the pressurized brake fluid to the wheel cylinders through the pressure control devices. A valve device is disposed in the first passage and connected to the second passage to selectively place one of a first operating position for communicating the master cylinder with the pressure control devices and blocking the communication between the master cylinder and the inlet of the auxiliary pressure source, and a second operating position for communicating the master cylinder with the inlet of the auxiliary pressure source and blocking the communication between the master cylinder and the pressure control devices.
