What is the function of brake fluid in cars and when should it be changed?
Brake fluid is an important solution, contributing to ensuring safety during car use, so car users need to clearly understand this type of solution and pay attention to replacing it periodically.
Besides engine oil, coolant... brake fluid is an important solution that helps the vehicle operate smoothly, stably and ensures safety during car use.
According to technical experts, brake fluid is a special liquid used to control the hydraulic brake system of cars. Unlike other types of solutions in cars, brake fluid has different physical properties. This type of solution has good force transmission ability, high boiling point and does not absorb water...
What does brake fluid do?
Just like engine oil contributes to lubrication, reduces friction and ensures smooth operation of the engine system. Brake fluid is also an important part of the car's brake system, protecting and optimizing the performance of the brake system.
The most important function of brake fluid is to ensure flexible and efficient power transmission at high temperatures and in hot and humid conditions. In addition, brake fluid also prevents corrosion of metal and non-metal parts in the brake system. At the same time, it has the ability to lubricate the parts in the brake system, ensuring smooth and stable operation. Because of its high boiling point, brake fluid helps prevent the formation of air bubbles in the brake system at high temperatures, helping to minimize decomposition and increase the durability of the brake system.
When to change brake fluid?
Over time, brake fluid will wear out. Even if the car is not used much, over time, brake fluid degradation will also reduce power transmission efficiency. In addition, brake fluid can be contaminated with various impurities such as dirt or metal shavings, causing the brake system to not operate smoothly.
If the brake fluid is degraded, during the use of the car when the driver often brakes or brakes suddenly, the heat generated will cause the brake fluid to boil and easily lead to brake failure (Brake Fade), making the brake less stable. Therefore, it is necessary to check and replace the brake fluid periodically.
The owner's manual of each car model will specify the specific time to change the brake fluid. However, most manufacturers recommend that car users should change the brake fluid every 2 - 3 years or 40,000 - 60,000 km depending on the conditions of use and the type of brake fluid.
Signs that brake fluid needs to be replaced
If you notice signs of weak brakes, having to press the brakes harder than usual to stop the car, or the brakes are stuck and do not release after you release your foot from the brake pedal, you should take the car to a service station or garage to check the brake system and change the brake fluid.
In addition, when detecting a vibration when braking, this may be due to worn brake pads or a problem with the brake system; there is a loud sound when braking... the brake system should also be checked and maintained.
