The brake master cylinder is a necessary part of the hydraulic brake. It is usually attached to the vacuum brake booster. And above the brake cylinder is located a translucent polyethylene tank with a regulator of level of brake fluid insufficiency. On the tank there are markups for minimal and maximal fluid levels. Depending on the design of the vehicle, the brake fluid reservoir can be mounted separately from the brake cylinders and attached to the body in the compartment under the car hood.

Brake master cylinder is required in order to convert the force applied to the brake pedal into extra brake fluid pressure for its subsequent transfer through the brake system. If you want to check out the functioning capacity of the master brake cylinder, look at the brake fluid level. The main brake cylinder determines the joint of the hydraulic drive circuits. The brake cylinder contains two pistons. At its bottom there are a few bolts that restrict their motion. Each valve is responsible for the pressure in a separate circuit. If, for some reason, one of the circuits does not work, the second loop still continues to function, thereby braking the car, though less efficient.

The most serious malfunction of the brake cylinder is considered the loss of impermeability. In this case, the brake cylinder starts leaking, and it's not difficult to see. The liquid flows over the body of the vacuum booster, and, consequently, its level in the tank decreases. And then it needs repair or even replacement of the brake cylinder.
