Abstract
A variable ratio of force-enlargement master cylinder for a braking system is described. The variable ratio of force-enlargement master cylinder has a cylinder, an outer piston, and an inner piston, in which comprise a plurality of cavities and openings therein. When a force is uniformly applied to the variable ratio of force-enlargement master cylinder, the flow rate of the fluid is preferably changed into a predetermined value by incorporating the cavities and openings located on the cylinder, the outer piston, and the inner piston in a suitable time.
