What is the function of brake fluid in a car, and when should it be replaced?
Brake fluid is a crucial fluid that contributes to safety during car use; therefore, car users need to understand this fluid and pay attention to replacing it regularly.
Along with engine oil and coolant, brake fluid is a crucial fluid that contributes to the smooth and stable operation of a vehicle, and helps ensure safety during car use.
According to technical experts, brake fluid is a special liquid used to control the hydraulic braking system of a car. Unlike other fluids in a car, brake fluid has distinct physical properties. This type of fluid has good force transmission capabilities, a high boiling point, and does not absorb water…
What is brake fluid used for?
Just like engine oil contributes to lubrication, reduces friction, and ensures the smooth operation of the engine system, brake fluid is also a crucial part of the automotive braking system, protecting and optimizing the performance of the braking system.
The most important function of brake fluid is to ensure smooth and efficient power transmission at high temperatures and in hot and humid conditions. In addition, brake fluid prevents corrosion of metal and non-metal parts in the braking system. At the same time, it lubricates the components in the braking system, ensuring smooth and stable operation. Because of its high boiling point, brake fluid prevents the formation of air bubbles in the braking system at high temperatures, minimizing degradation and increasing the lifespan of the braking system.
When should you change your brake fluid?
Over time, brake fluid will degrade. Even in lightly used cars, the brake fluid will degrade over time, reducing its effectiveness in transmitting power. In addition, brake fluid can become contaminated with various impurities such as dirt or metal particles, causing the braking system to malfunction.
If brake fluid degrades, during frequent use of the vehicle, especially when the driver applies the brakes lightly or brakes suddenly, the heat generated can cause the brake fluid to boil, easily leading to brake fade and resulting in unstable braking. Therefore, brake fluid should be checked and replaced regularly.
Each car model's owner's manual will specify when to change the brake fluid. However, most manufacturers recommend changing brake fluid every 2-3 years or every 40,000-60,000 km, depending on usage conditions and the type of brake fluid used.
Signs that indicate your brake fluid needs replacing.
If you notice signs such as weak brakes, having to press the brake pedal deeper than usual to stop the car; or brakes sticking and not releasing after you take your foot off the brake pedal, you should take your car to a service station or garage to have the braking system checked and the brake fluid replaced.
Additionally, if you notice vibrations in the brakes, this could be due to worn brake pads or a problem with the braking system; if you hear loud noises when braking, you should also have your braking system checked and serviced.
