In the brake system of a vehicle, the brake master cylinder is the first component that gets activated by tapping the brake pedal. It is a control device that converts force into hydraulic pressure. 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.
How to replace a master cylinder?
It is not very tough for one to replace a master cylinder with a new one when the former gets bad due to whatever reason. Nonetheless, you need to be familiar with the process of replacing it yourself. Firstly, you need to remove the old brake master cylinder. Make sure to unplug the electrical connectors from the cylinder. After removing it, you’ll need to bench bleed the new master cylinder. Now, install the new master cylinder in its place and bleed the brake system by following the general procedure.
