A dual action hydraulic clutch system. The system includes a master cylinder having an outer piston therein, wherein the outer piston includes a channel therethrough that can receive an inner piston therein. A gap is formed between the outer and inner pistons, such that activation of the outer piston activates the inner piston once the outer piston has traveled a length of the gap. The outer piston forces hydraulic fluid through an outer outlet connected to a hydraulic clutch, and the inner piston forces hydraulic fluid through an inner outlet connected to a rear brake, allowing a user to simultaneously disengage the clutch and engage the rear brake. A lever is connected to the outer piston, such that the lever can move the outer piston between a resting position, a clutch position, and a brake position. The master cylinder can secure to a support surface via a mounting bracket thereon.
