Should Brake Fluid Be Replaced at 40,000 Kilometers?

[VanRobert]

Brake fluid should be replaced at 40,000 kilometers. The procedure for replacing brake fluid is as follows: 1. Use a machine to extract the old brake fluid from the drain nut, then continuously add new brake fluid to the reservoir, repeating this process; 2. Continue until the discharged brake fluid is clear and free of air, then use the same method to replace the brake fluid in the remaining three wheels. Brake fluid, also known as hydraulic brake fluid, should be purchased from reliable manufacturers, and the higher the grade, the better. All liquids have the characteristic of being incompressible. In a sealed container or a pipeline filled with liquid, when pressure is applied to the liquid, it quickly and uniformly transmits the pressure to all parts of the liquid. Hydraulic braking systems operate based on this principle.
