How does the master cylinder in a car work?
Our car braking system works effectively thanks to a very important component known as the master cylinder. The brake master cylinder converts mechanical pressure applied on the brake pedal into hydraulic pressure that is needed by the brake calipers to squeeze the brake pads and slow the car down.
What should I do if my master cylinder is leaking?
However, if the fluid is leaking out of nearby brake lines or tubing, then your master cylinder is probably not the problem. Apply pressure to the brake pedal until it comes to a stop and then hold the pedal there, sustaining the pressure.

The brake master cylinder converts mechanical pressure applied on the brake pedal into hydraulic pressure that is needed by the brake calipers to squeeze the brake pads and slow the car down. Unfortunately, like all other components in the car, the brake cylinder can also fail.
What happens when you bleed the master cylinder?
Air bubbles in the brake lines will decrease the amount of force the brake pedal applies to the brake pad or shoe at each wheel. Air bubbles will also make the brake pedal feel “spongy,” meaning when you press the brake pedal down, little or no braking force will be felt by the driver. Bleeding the Master Cylinder Step 1
