The typical clutch hydraulic system on Dodge Caliber consists of a clutch master cylinder (2), slave cylinder (5), and an interconnecting fluid line. Clutch hydraulic fluid is supplied by the brake system via the brake master cylinder reservoir (1). The clutch pedal pushrod (4) is adjustable. On some models, the slave cylinder is integrated with the clutch release bearing.
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. Slave cylinder force transmits through the integral release bearing, which is in contact with the pressure plate diaphragm spring. As additional force is applied, the bearing depresses the diaphragm spring fingers inward on the fulcrums. The action moves the pressure plate rearward, relieving clamping force on the clutch disc.
