Is it time for you to change your brake fluid?

Many traffic accidents tell us that brake safety, more important than anything else, many accidents are due to car brake failure, but few people will regularly care for their car’s brake system,. Some car owners don’t change their brake fluid for four or five years, which is a very bad habit.
Brake fluid, also known as automotive brake oil, is a functional fluid that transmits pressure in the vehicle’s brake system to enable the brake system on the wheels to achieve braking action. The main functions of brake fluid are energy transfer, heat dissipation, corrosion and rust prevention, and lubrication.

Why does brake fluid need to be changed regularly?

1. Brake fluid absorbs water easily. If it is not replaced for a long time, the brake fluid will corrode our braking system and bring great safety risks.
2. The boiling point of brake fluid will be lowered after absorbing water, resulting in insufficient braking pressure, which directly affects the braking effect.
3. If the brake fluid is not changed for a long time, the deposits and impurities in the brake line will also cause the brake system to malfunction and affect the brake performance.

How to determine whether it is time to change the brake fluid?

When the water content exceeds 3%, it is recommended to replace the brake fluid; if the water content exceeds 5%, then it must be replaced.
After a new car has been running for a year, its brake fluid may have inhaled about 2% of water; when it has been running for a year and a half, the water content can reach 3%; when it has been running for more than five years, the water content of the brake fluid will reach 7-8%.
So if the local climate is dry and the owner does not drive aggressively, then the brake fluid can be changed once every 3-4 years. If the local climate is very humid, or if you often drive through water, then it is recommended to shorten the replacement cycle, preferably once a year.
