How to Determine if the Clutch Master Cylinder is Faulty?

[SanJaxon]

Methods to determine if the clutch master cylinder is faulty: 1. Check for oil stains on the exterior of the master cylinder and slave cylinder, as oil stains indicate leakage; 2. Observe the extension length of the slave cylinder push rod when depressing the clutch pedal. If the extension is insufficient, it suggests pressure loss, or if the push rod retracts when extended, it also indicates pressure loss. The clutch master cylinder is the component connected to the clutch pedal and linked to the clutch booster via a hydraulic line. Its function is to collect pedal travel information and, with the booster's assistance, disengage the clutch. When the driver presses the clutch pedal, the push rod moves the master cylinder piston, increasing hydraulic pressure, which travels through the hose to the slave cylinder, forcing the slave cylinder push rod to disengage and push the release bearing forward. When the driver releases the clutch pedal, the hydraulic pressure is relieved, and the release fork gradually returns to its original position under the action of the return spring, causing the clutch to re-engage.
