A hydraulic pressure multiplier having a housing, a bore in the housing and an outer piston slidably positioned within the bore. The pressure multiplier also includes an inner piston having a bore therethrough, the inner piston being positioned within a bore within the outer piston. An opening is provided through an end wall of the outer piston, and a mechanism is provided to selectively control hydraulic fluid flow into the bore within the outer piston. Hydraulic fluid first flows through the opening in the outer piston and through the bore through the inner piston to actuate a slave cylinder or a hydraulic piston within a brake. After a threshold pressure is reached within the slave cylinder, the valve closes and the outer piston is caused to move axially, thereby providing an increased hydraulic pressure within the slave cylinder.
