Well, the master cylinder is tasked with supplying hydraulic pressure to the braking system. So when you initially step on the brake pedal the linkage activates a piston within the system and this piston then displaces hydraulic fluid.
The clutch is exactly the same as any other hydraulic piston arrangement. You have a master cylinder which is a piston that moves hydraulic fluid when you move it up and down, you have a pipe through witch the hydraulic fluid moves and you have a slave cylinder that moves as a result of the fluid moving. The master cylinder is just a piston. Written Dec 2, 2015 â¢ View Upvotes.
