If you want to know more about how a master cylinder works and the best master cylinders available out there, read ahead to find out.

How does a master cylinder work?

A master cylinder comprises a reservoir, cylinder, piston, a returning spring, and a valve. The moment the brake pedal is depressed, the piston inside of the system moves, opening the inlet valve that leads the brake fluid in the reservoir to reach to the compression chamber. This brake fluid is then compressed inside the chamber evenly due to the movement of the piston. After this, the outlet valve slowly opens, and the brake fluid is transferred further to the brake lines for brake actuation.
