What is the difference between Clutch Master Cylinder and Clutch Slave Cylinder?

Clutch Master Cylinder is connected directly to the clutch pedal and is part of the hydraulic system that generates hydraulic pressure. Hydraulic fluid is stored in a reservoir which is connected through hoses where brake fluid will flow to the clutch slave cylinder.

Clutch Slave Cylinder is used in the hydraulic clutch system and is usually mounted in the transmission, it can be found either on the outside or on the inside. It works together with the clutch master cylinder to disengage the clutch so that the transmission can be safely shifted.

How does it work?

When pressed on the clutch pedal, the clutch slave cylinder receives pressure from the master cylinder that transmit hydraulic pressure to the clutch slave cylinder which disconnects the power of the engine to the transmission. Making it safe for the transmission to be shifted . When the clutch pedal is released a return spring on the slave cylinder will force the brake fluid back into the clutch master cylinder.
