What is the meaning of brake fluid?

Brake fluid is a liquid used in the braking system of a car and is an important part of the function of the braking system of a vehicle. It is mainly composed of ethylene glycol, polyethylene glycol and other additives.It serves several important purposes that ensure the safety and efficiency of the braking system. This article will discuss the significance of brake fluid and its role in vehicle safety.

Firstly, brake fluid is responsible for transmitting the force applied on the brake pedal to the brake pads or shoes. When the brake pedal is pressed, hydraulic pressure is created, which is then transferred through the brake lines to the individual brakes. This pressure is what causes the brake pads or shoes to press against the rotors or drums, resulting in the vehicle's deceleration or stopping. Without brake fluid, this transfer of force would not be possible, rendering the braking system ineffective.

Secondly, brake fluid plays a crucial role in maintaining the proper operation of the braking system. It has a high boiling point, which allows it to withstand the intense heat generated during braking. This is particularly important in situations where the brakes are used continuously, such as during long descents or heavy braking. If the brake fluid were to boil, it would create air bubbles in the system, leading to a loss of braking power or even complete brake failure. Therefore, the high boiling point of brake fluid ensures that the braking system remains functional even under extreme conditions.

Furthermore, brake fluid also serves as a lubricant for various components within the braking system. It helps to reduce friction and wear between the moving parts, such as the pistons and calipers. This lubrication is essential for the smooth operation of the brakes and prevents premature damage or failure of these components. Without brake fluid, the braking system would experience increased friction and wear, leading to decreased performance and increased maintenance costs.
