What Is Hydraulic Brake
Krunal Rajput
With the understanding of the braking system in automobiles, discussing the hydraulic type is very necessary as it’s widely used.
The braking system uses hydraulic fluid to transmit the brake pedal or level force to the final drum shoes or disc caliper for the braking to prevail.

In a hydraulic braking system, the mechanical force from the brake pedal is transmitted and converted into the hydraulic pressure by the help of the master cylinder. This will be further explained.
The hydraulic brake system works with the principle of pascal’s law. The laws state whenever pressure is applied on fluid it travels uniformly in all the directions.
Today we’ll be looking at the definition, functions, construction, applications, components, diagram, types, working, as well as advantages and disadvantages of the hydraulic braking system.

ConstructionThe construction of a hydraulic braking system involves the arrangement of the following part:
Brake pedal or level, a pushrod, which is also known as actuating rod, a master cylinder assembly carrying piston assembly.
It’s made up of either one or two pistons, a return spring, a series of gaskets or o rings, and a fluid reservoir.

The construction of a hydraulic braking system is containing reinforced hydraulic lines and the brake caliper assembly consists of one or two hollow aluminum or chrome-plated steel pistons.
It’s known as caliper pistons. There is a set of thermally conductive brake pads and a rotor, which is also known as brake disc or drum attached to an axle.
A glycol-ether based brake fluid filled the system to transmit to force to four wheels. Though other fluids can also be employed.

Suddenly, manufacturers begin to design passenger vehicles with drum brakes on the four wheels.
Conventionally, disc brake is used in the front wheel while drum brakes are employed for the rear wheel.
The disc brakes have better heat dissipation and greater resistance to fading, and as well safer than drum brakes.
This is why four-wheel disc brakes have vastly increased over the year. Also, hydraulic brakes offer faster and more consistent pad withdrawal upon the pedal release.
