Abstract: A master cylinder for vehicle braking systems includes a housing having a central cavity, at least one fluid supply inlet port, at least one pressure outlet port, and a flange at one end thereof. A piston actuation mechanism within the central cavity is moveable between a first position wherein the central cavity is in fluid communication with the fluid supply inlet and a second position where the central cavity is in fluid communication with the pressure outlet. A cup-shaped end cap is fastened to the housing flange in a fluid sealing relationship wherein the cup-shaped end cap receives at least a portion of the piston actuating mechanism therein and further retains the piston actuation mechanism in an operational configuration within the housing.
