What is the moisture content of brake fluid?

[AdelynAnn]

Brake fluid moisture content is below one percent. Brake fluid, also known as hydraulic brake fluid, is a functional liquid that transmits pressure in a vehicle's braking system, enabling the braking system on the wheels to perform braking actions. The steps for replacing brake fluid are: 1. Park the vehicle on a flat surface, turn off the engine, and open the engine compartment to extract the fluid from the reservoir; 2. Use a funnel to fill the reservoir with new brake fluid; 3. Use a jack to lift the vehicle and start removing the tires from the rear wheels; 4. Remove the rubber dust cap on the brake caliper; 5. Use a wrench to loosen the bleeder screw and attach a rubber tube to it, connecting it to a drain bottle; 6. Press the brake pedal inside the vehicle while observing the fluid drainage until the fluid level in the engine compartment reservoir reaches the lower limit; 7. Start the vehicle and perform a brake test in a relatively safe area.
