How often do you need to change the brake fluid?
As a rule, it is recommended to change the brake fluid once a year or every two years. Of course, this is also highly dependent on driving and mileage.
The reason is that the brake fluid is very hygroscopic, which means that it tends to absorb water. This indicator dramatically lowers its boiling point. Exceeding the recommended service life of the brake fluid adversely affects the efficiency of the brake system up to its failure. It is recommended to change the brake fluid every 1.5-2 years.
