The braking system is a system in the car that can provide a very high safety function. In this braking system there are many components that work together to provide a sense of security during the trip. One of the important components in the braking system is the brake master cylinder.
Then, what are the functions of this master cylinder? And how does the brake master cylinder work? The following below is a complete review that you should know.
Brake Master Cylinder Functions
Basically, whether it’s a drum or disc type hydraulic braking system, it must use this master cylinder. The main function itself is to increase the pressure that comes from the pedal when the pedal is pressed by the driver. The pressure is then converted into hydraulic force. This is what will press the piston on the caliper or cylinder of each car wheel. Actually, there are several other functions of the brake master cylinder. The following is in full below:
- Has a function to change the compressive energy that comes from the pedal or brake lever.
- Has the function of being a place for the brake pedal to be stepped on.
- Has a function to convert the mechanical energy generated by pressing the brake pedal into a hydraulic force.
- Has the function of being a place to refill the hydraulic system.
By reading the explanation above, you can conclude that this component is very important in a braking system. When the master cylinder works to its full potential, the braking system used throughout the trip will certainly run smoothly. When the braking system is smooth, passenger safety will also be maintained.
How the Brake Master Cylinder Works
Now you know the function of this component. So let’s discuss how it works. The way this component works is also divided into two parts, namely when the brake pedal is pressed and not pressed. Here’s the full explanation:
1. When the Brake Pedal is Depressed
When the car brake pedal is depressed, the piston will move towards the right. The piston cup will close the compensation channel so that it will cause the hydraulic pressure in the master cylinder to increase. And then this pressure is transmitted to the wheel cylinders when using drum brakes, or to the calipers for disc brakes.
2. When The Brake Pedal Is Not Depressed
When the braking pedal is not depressed, the piston cup on the master cylinder is between the inlet and also the compensation. This will cause two channels between the master cylinder and the reservoir tank.
The way the master cylinder works, there is a difference between when the pedal is stepped on and not stepped on. So with the information above, you will find out how the brake master cylinder works and also functions. Hope it is useful.
