Hydraulic braking system use two types of brakes namely disc or drum brakes. The brakes in modern cars are provided for all four wheels. However, the front brakes play a leading role as compared to rear brakes. This is because when rear brakes are applied, the weight of the car is automatically thrown on to the front wheels, which at high speeds can cause the whole car to flip over, or take a wild turn.

Regardless, the mechanism by which the braking power is generated and then transferred from the brake pedal is through a hydraulic system. The circuit contains two types of cylinders – a master cylinder at the centre and slave cylinders at the front and back. The brake fluid rests in the master cylinder.
When the driver plants his/her feet on the brake pedal, that in turn depresses a piston that pushes the fluid from the master cylinder out into the slave cylinders via connecting pipes. Now, the overall ‘face’ area of the pistons in the slave chambers are greater thus allowing for more force to be exerted forward.
As a relatively early form of force transfer mechanism, the hydraulic system has remained quite successful. One of the main advantage of using fluid for transmission of pressure, is that unlike gas, the force is evenly distributed in all directions. Therefore, advancements in hydraulic breaking technology have seen the development of specific components that exhibit greater sensitivity to a trigger from the driver or increase the force distribution efficiency.
In other words, you would ideally want to receive the right kind of feedback from the brakes, where its neither too prolonged to produce the braking effect, nor too light that a mild sliding of the feet on the brake pedal produces unwanted braking that could cause your vehicle to go out of control.
