Abstract
A vehicle braking system including a master cylinder having a pressurizing piston fluid-tightly and slidably received in a cylinder housing and cooperating with the cylinder housing to define a pressurizing chamber and an assisting chamber on opposite sides of the piston, a brake operating member for applying a pressurizing force to the piston, a wheel brake cylinder connected to the master cylinder for activating a brake for braking a wheel, a hydraulic pressure source for pressuring a working fluid, a reservoir, a first flow control device for controlling flows of the fluid between the assisting chamber, and the hydraulic pressure source and reservoir, and a second flow control device or controlling flows of the fluid between the pressurizing chamber, and the hydraulic pressure source and reservoir.
