Self-adjusting clutch
This vehicle has a hydraulically operated clutch. The brake master cylinder reservoir has a separate chamber and is used to supply the
hydraulic clutch system with fluid.
Depressing the clutch pedal builds up pressure in the clutch master cylinder and operates the release bearing integrated in the clutch slave
cylinder.
The hydraulic clutch system has the following advantages:
Automatic adjustment.
Low operating effort.
Minimal wear.
Reservoir
The brake fluid reservoir supplies both the hydraulic clutch system and the brake system with brake fluid.
The hydraulic clutch system and the brake system are separate inside the brake fluid reservoir. In the event of any leaks in the hydraulic
clutch system the brake system remains fully operative.
Clutch Master Cylinder
The pressure required to operate the clutch system is produced in the clutch master cylinder.
When the clutch pedal is depressed the piston rod moves the piston in the clutch master cylinder. This displaces the hydraulic fluid in the
clutch master cylinder, which in turn displaces the hydraulic fluid in the clutch slave cylinder via the high - pressure line.

Plastic housing
The central slave cylinder is fixed to the clutch housing with three bolts, together with an integrated release bearing. The release bearing is
a press - fit on the clutch slave cylinder.
The hydraulic fluid which is displaced by the master cylinder piston moves the piston in the clutch slave cylinder, which in turn moves the
release bearing in an axial direction. The release bearing presses against the tongues of the diaphragm spring with the inner bearing ring.
This breaks the friction contact between the clutch disc and the flywheel.
When the clutch pedal is released the diaphragm spring returns the piston in the clutch slave cylinder to its original position. This restores
the friction contact between the clutch disc and the flywheel.
