Clutch control. The clutch release lever is actuated by the hydraulic system. The system compensates for clutch wear automatically, meaning it does not require any maintenance. The primary cylinder is located on the clutch pedal, and the slave cylinder is located on the gearbox, the cylinders are connected to each other using a hydraulic pipeline. The same fluid flows in this pipeline as in the brake system. A low level in the brake fluid reservoir can also be caused by some defect in the clutch control. However, this is not dangerous for the brake system: the intake pipe fitting for the hydraulic clutch drive is located quite high on the reservoir, so there is always a sufficient amount of fluid for the brake system.
Clearance between bearing and clutch release levers. Since the clutch pedal is not being depressed, this clearance allows the constant pressure to be removed from the bearing. As the lining wears, the clearance decreases (pedal free play increases).
pressure plate approaching the clutch release bearing. If the bearing rests against the lever without play, then the pressure plate belleville spring rests on the bearing. Instead of pressing the driven plate against the bearing surfaces of the flywheel and pressure plate, the spring is weakened and the friction force decreases - the clutch slips.
Clutch disengagement. When the clutch pedal is depressed, the clutch release bearing overcomes the tension force of the Belleville spring. The load from the driven disk is removed, with the pedal fully depressed, the disk is retracted and allowed to rotate freely.
Clutch engagement. The disc spring of the pressure plate slowly presses the driven plate against the flywheel until it rotates at the same speed as the flywheel. Thus, the force is transferred gently. In this case, the contact surfaces rub against each other for a short time before the friction becomes so great that all the engine power begins to be transferred to the gearbox.
