Change brake oil after tens of thousands of kilometers of car

In general, based on professional advice and the vehicle owner's manual,Brake FluidThe replacement cycle is two years or about 40,000 kilometers. However, every vehicle has its own uniqueness, so when it comes to changing brake fluid, it is best to refer to the owner's manual or consult with 4S shop maintenance personnel to ensure that the replacement time matches actual needs.

In addition to replacing it according to fixed intervals, you can also judge whether it needs to be replaced based on the usage of the brake fluid. If you notice that your brakes are becoming softer and the braking distance is significantly longer while driving, this may be a sign that your brake fluid may need to be replaced.

At this time, it is recommended to go to the 4S store immediately for a special instrument test to measure whether the brake fluid has oxidized and deteriorated or the water content is too high. If the test result is unqualified, it is crucial to replace the brake fluid in time, because safety is the primary consideration.

But why do we need to change brake fluid regularly? Brake fluid that has not been replaced for a long time will lose its original performance and even become turbid. Such brake fluid will lower its boiling point when using the brake system, resulting in reduced braking performance and increased risks during driving. In addition, if the moisture content of the brake fluid is too high, it will also affect the braking system.

On the one hand, moisture will cause the brake cylinder to rust, affecting the efficiency of the braking system; on the other hand, excessive moisture content will cause the boiling point of the brake oil to change, prone to air lock, making the brakes softer, and may eventually cause the brakes to malfunction.
