The clutch assembly consists of the pressure plate, the clutch cover, the diaphragm spring pivot pin and the driven
plate assembly.
The clutch pedal is connected to the release bearing through the shift fork.
The driven plate assembly is installed between the flywheel and the pressure plate.
For models with MSG transmission and MUA transmission, the push-type clutch is used.
Diaphragm spring pressure holds the driven plate against flywheel and the pressure plate to provide the friction
necessary to engage the clutch.
Depressing the clutch pedal moves the shift fork against the release bearing.
The release bearing forces the diaphragm to overcome the force of the diaphragm spring and separate the driven
plate from the flywheel and pressure plate to disengage the clutch.
For model with MUX transmission, the pull-type clutch is used. The pull-type clutch is disengaged by pulling the
release lever (release bearing) to disengage the pressure plate.

The master cylinder converts mechanical energy into hydraulic energy.
Depressing the clutch pedal causes the push rod to move against the piston to close the return port.
Clutch fluid is forced out of the master cylinder.
Releasing the clutch pedal causes the return spring to force the piston back to its original position.
The return port is opened and the clutch fluid flows back into the fluid reservoir.
Quickly releasing the clutch pedal will cause the fluid pressure at the return spring side to be lower than the fluid
pressure at the push rod side.
This allows the fluid at the push rod side to quickly flow to the return spring side through a port in the piston head.
This equalizes the pressure at both sides of the piston.
