CLUTCH RELEASE SYSTEM 2 2. CLUTCH SYSTEM COMPONENTS A. CLUCTH MASTER CYLINDER The clutch master cylinder is mounted on clutch pedal cast bracket with its fork connected the Clutch pedal. The master cylinder is a control device that converts mechanical energy which comes by pressing the clutch pedal into hydraulic pressure, in order to actuate the concentric slave cylinder which is located at the other end of the hydraulic system. As the piston moves along the bore the mechanical effort is converted into hydraulic pressure. The pressure remains same in the hydraulic line while force is magnified at slave cylinder end because of increased piston area of slave cylinder. NOTE The clutch master cylinder parts are not serviceable and needs to be replaced completely if found defective. B. CONCENTRIC SLAVE CYLINDER (CSC) The clutch control mechanism is fully hydraulic. There is no mechanical transfer (fork) from an external slave cylinder. The concentric slave cylinder (CSC) means that the slave cylinder is integrated with the throw out bearing. The concentric slave cylinder (CSC) is extremely efficient and reliable and the throw out bearing is accurately centered and secured to the clutch housing using two screws. The bearings and friction surfaces do not need to be lubricated. The bearing on the concentric slave cylinder (CSC) is self-centering against the clutch diaphragm spring. Advantages of CSC: Lighter pedal effort resulting in comfortable drive.
