Does the brake fluid need to be changed if the water content is 3%?

whenBrake FluidWhen the moisture in the brake fluid reaches 3%, we should consider replacing the brake fluid. Because the water content exceeds this, problems may occur in the brake fluid, which will affect the normal operation of the brake oil pipe. Especially under high temperature conditions, water will evaporate into gas, causing air lock in the brake oil pipe.

Because the gas can be compressed, the braking stroke becomes longer. As a result, the brake response speed will be slower, and there may even be lag or even failure. Therefore, when the water content of the brake fluid reaches 3%, we strongly recommend replacing it to ensure driving safety.

In addition, failure to replace brake fluid for a long time may cause corrosion of the brake system, posing greater safety risks. In order to avoid this situation from happening, we need to determine the brake fluid replacement cycle according to the use of the vehicle. If the vehicle is used frequently, it is recommended to replace it around 30,000 kilometers. For vehicles that are used less frequently, the replacement cycle can be extended accordingly, generally around 50,000-60,000 kilometers.

It should be noted that the above data is only for reference. In fact, it is necessary to determine whether to replace the brake fluid based on the specific usage of the brake fluid. When it is detected that the water content of the brake fluid exceeds 3%, regardless of whether it reaches 5%, it is recommended to replace it to ensure driving safety.
