The clutch hydraulic system is responsible for engaging and disengaging the clutch. Depressing the clutch pedal develops fluid pressure in the clutch master cylinder. This pressure is transmitted to the slave cylinder through a connecting line. In turn, the slave cylinder operates the clutch release lever. See Fig 1.

Slave cylinder spring force causes the release lever to hold the release bearing in contact with the diaphragm spring, also known as bearing preload. During a clutch pedal actuation, hydraulic fluid pressure applies force through the release lever to make the bearing press the diaphragm spring fingers inward on the fulcrums. This action moves the pressure plate rearward, relieving clamp force on the clutch disc.
