The clutch master cylinder converts your pedal push into hydraulic pressure that actuates the clutch through the slave cylinder. If a leaking or failed master cylinder is the cause of a soft, sinking clutch pedal or trouble shifting, this unit replaces it; diagnose the cause first, since those symptoms can have other sources. Country of origin: Italy.
