1. The clutch master cylinder is the component that is connected to the clutch pedal and connected to the clutch booster via the oil pipe. Its function is to collect information on pedal travel and to use the booster to disengage the clutch.

2. When the driver depresses the clutch pedal, the push rod pushes the master cylinder piston to increase the oil pressure and enters the wheel cylinder through the hose, forcing the wheel cylinder rod to push the release fork and push the release bearing forward; when the driver releases the clutch pedal, the release fork gradually returns to its original position under the action of the return spring when the hydraulic pressure is released and the clutch is again in the engaged position.
