The clutch master cylinder is a key hydraulic component in the clutch system of a manual transmission vehicle. Its working principle is straightforward: the driver depresses the clutch pedal → the master cylinder converts the pedal force into hydraulic pressure → the hydraulic pressure pushes the driven cylinder → the clutch disc disengages → the vehicle can smoothly shift gears.

Core Functions:
Hydraulic Pressure Conversion: Precisely converts pedal force into hydraulic output, with linear response and clear feel.
Sealed hydraulic circuit: Built-in high-precision seals prevent brake fluid leakage and maintain stable line pressure.
Original factory-grade pedal feel: Cylinder diameter of 15.87mm is consistent with the original factory design, and the release force and return spring force match the original vehicle settings.
45° mounting angle design: The flange adopts a 45° bevel design (Mounting Size: Φ26.5/72/45°), adapting to the original vehicle installation space and ensuring precise positioning.
Fatigue-resistant and high-temperature resistant: The sealing material is adapted to the frequent pedaling and temperature changes in off-road/commercial scenarios, and its service life meets the original factory requirements.
