Modern cars use brake fluid as a liquid chemical solution for hydraulic braking. Also, it converts hydraulic pressure in the brake system into mechanical force by using one or more pistons. Its function is to hold and guide the brake pads. The brake caliper is an essential part found in a disc brake system. Brake lines are rigid and constructed using double-wall steel tubing. Simply put, they are like pipes in which the braking fluid passes from the master cylinder to the brakes. The brake line and hose transfer high-pressure fluid between the various components. Therefore, a reservoir is required to maintain the proper level. In some cases, due to small leaks, the brake fluid level drops in the master cylinder. There must be a sufficient amount of braking fluid throughout the assembly. The storage is usually small and is connected directly to the master cylinder for proper operation of hydraulic braking. The brake fluid reservoir stores and protects the vehicle’s brake fluid so the braking system can function correctly. There are two main types of wheel cylinders: stepped wheel cylinders and single-piston wheel cylinders. Its function is to force the shoes into contact with the drum and protect the vehicle from friction. The wheel cylinder is located in each wheel and is usually located at the top of the wheel, above the shoe.
This device converts hydraulic pressure into mechanical pressure to push the brake shoes towards the drum. The master cylinder consists of various parts such as a reservoir, piston, rubber cup, pressure check valve, and more. In this, the fluid is compressed and pressurized into the cylinder, which is transmitted via hydraulic lines to the brake assembly. A master cylinder performs multiple functions, including developing pressure, equalizing the brake pressure, preventing contaminants, etc. This is the key part of the system that converts the pressure on the brake pedal into hydraulic pressure. After the action of the brake pedal, the master cylinder comes into play. The pedal is connected to the master cylinder with a mechanical contact, such as a spring.
BRAKE FLUID IMAGE DRIVER
When the driver applies force on the brake pedal, the movement of the vehicle slows down or stops. The whole braking assembly will start working when the brake pedal is pressed.

Hydraulic brakes are entirely dependent on the principle of Pascal’s law. In addition, some types of motorcycles also use these brakes. The drum type of hydraulic braking system is primarily found in low-speed four-wheelers, while the disc type of hydraulic brakes is used in almost all cars. The first four-wheel hydraulic brake system for a motor car was developed and installed by Ernest Walter Weight in 1908. This type of braking system transfers pressure from the controlling mechanism to the braking mechanism using brake fluid, usually glycol ether. Brakes that are operated using hydraulic pressure are called hydraulic brakes. The fluid pressure is known as hydraulic pressure. A hydraulic system uses liquid under pressure to transfer force, move an object, or increase its force.
