Automotive brake fluid is a vital part of a vehicle's braking system, and its proper operation is essential for driving safety. Therefore, regular change of brake fluid is one of the important measures to ensure driving safety and prolong the life of the braking system. So, how often should you change your brake fluid?
Generally speaking, the brake fluid used in the vehicle's braking system is hydraulic brake fluid, which achieves the braking effect through hydraulic transmission. Hydraulic brake fluid not only needs to maintain stability in high temperature and high pressure environments, but also has good anti-rust and anti-corrosion properties. Over time, brake fluid will gradually lose its performance due to moisture absorption, oxidation, etc. Therefore, regular replacement of brake fluid can effectively reduce the occurrence of brake system failure and improve the reliability of the brake system.
According to general maintenance recommendations, the brake fluid replacement interval is usually every two years or every 20,000 km, whichever comes earlier. However, this time and mileage are not fixed, as the usage of each car is different. Therefore, we need to judge whether we need to change the brake fluid according to the actual situation.
There are several indicators that can help us determine if the brake fluid needs to be replaced:
1.The appearance of brake fluid: fresh brake fluid is usually transparent or light yellow, if you find that the brake fluid is turbid, emulsified, blackened, etc., it means that the brake fluid has been seriously polluted and needs to be replaced in time.
2.Boiling point of brake fluid: Brake fluid will reduce its boiling point due to moisture absorption during use. If the boiling point of the brake fluid is too low, it is prone to the formation of air bubbles, which can lead to the failure of the brake system. Therefore, it is very important to check the boiling point of brake fluid regularly.
3.Brake pedal feel: If you find that the brake pedal feels soft during braking, or requires a long stroke to achieve normal braking effect, it may be that there is a problem in the braking system and the brake fluid needs to be checked and replaced in time.
To sum up, the replacement cycle of brake fluid is generally every two years or every 20,000 kilometers, but the specific replacement time and mileage need to be comprehensively judged according to the appearance, boiling point and feel of the brake pedal. In addition, in special situations, such as driving in bad road conditions or hot environments, the brake fluid change interval may need to be shortened.
Finally, I would like to emphasize that the replacement of brake fluid is a technical task, and it is recommended to go to a professional car repair service organization to change it to ensure the safety and effectiveness of the replacement process. Only by regularly checking and changing the brake fluid can we ensure the safety of the road.
