Can brake fluid with 2.5% water content still be used?

Brake FluidThe water content exceeds 2.5%, which means that the brake fluid is close to exceeding the standard, which requires the attention of car owners. Professional testing instruments display the quality of the brake fluid through three lights: the green light means normal, the yellow light means the water content has reached about 2.5%, and the vehicle can still travel about 3,000 kilometers at this time; and the red light means the water content of the brake oil has reached If it exceeds 5%, the brake fluid must be replaced immediately.

Why does the water content of brake fluid exceeding the standard value cause safety hazards? When the moisture in the brake fluid reaches a certain proportion, it will evaporate and vaporize under high temperature conditions, forming vapor lock. This will result in sluggish braking, posing a huge danger to the driver, especially on highways or in situations where emergency braking is required.

For some car owners, they may be lucky and think that applying more brakes will solve the problem. However, in reality this approach is wrong and dangerous.

Therefore, in order to ensure driving safety, we recommend regular testing and replacement of brake fluid. According to the results of professional testing instruments, when the water content of the brake fluid is close to 2.5%, although the vehicle can still drive for a period of time, this does not mean that we can ignore the quality of the brake fluid. Instead, it should be regarded as a warning signal, reminding us to replace the brake fluid in time to ensure the normal operation of the braking system.
