Abstract
The invention is directed to a wheel braking system having a master cylinder and a wheel brake cylinder which is communicated with the master cylinder through a brake fluid supply passage, and which is operatively mounted on a wheel for applying a braking force to the wheel. A suction device, such as a fluid pump, is provided for producing a negative pressure in the wheel brake cylinder. An initial pressure supply device, such as an accumulator, is also provided for supplying a predetermined amount of the brake fluid into the wheel brake cylinder when the braking operation is initiated. Accordingly, brake pads for braking the wheel may be separated from a brake rotor or brake drum respectively with a predetermined clearance, and the amount of the brake fluid which is consumed by the master cylinder when the braking operation is initiated, is not increased.
