How often to change Brake Fluid?
A working brake system is the key to safe movement, which is why it is so important to monitor the brakes and change the timing in time. Those drivers who do not neglect their own and others' lives, are not infrequently interested in how often to change the brake fluid in order to observe one of the most important intervals for replacing consumables.
Running ahead and not forcing me to read the whole article, I’ll answer right away - you need to change the brake fluid at least once after two years of operation, and if it is a sports car, then it is two to three times more often.
Why change brake fluid?
Manufacturers do not come up with numbers for the frequency of replacement of brakes, but regulate them based on the composition of the liquid and its properties.
_For reference: _ the boiling point of the brake fluid is about 200 - 260 ° C, but hygroscopicity (moisture absorption) is modern lower this threshold, while the fluid when moving around the city can heat up to 150 - 180 ° C. And when this boiling point is reached, air bubbles form, which leads to the release of brake fluid into the reserve tank, and as a result, a low level will not allow you to create the required pressure during sudden braking, failure of the brake pedal is inevitable!
When the moisture content in the brake fluid exceeds 3%, the boiling point is reduced from 30 to 50 ° C.
