Technician Handbook ! 302 Manual Transmissions & Transaxles Hydraulic Clutch In a hydraulic clutch system, there are three major components: System • Master cylinder • Release cylinder • Clutch pedal The master cylinder stores hydraulic fluid in the reservoir and provides pressure for system operation. When the clutch pedal is depressed, pressure is built up in the master cylinder forcing fluid into the release cylinder, which causes the clutch release fork to move. The release fork and release bearing compress the diaphragm spring of the clutch cover to disengage the clutch disc. Technical Training 15
