Can I Change the Brake Fluid Myself?

[DelJulianna]

Brake fluid can be changed by yourself. Brake fluid, also known as hydraulic fluid, is a functional liquid in the vehicle's braking system that transmits pressure to enable the braking action on the wheels. The functions of brake fluid are: 1. It has a very low freezing point, ensuring good fluidity at low temperatures; 2. It has an extremely high boiling point, preventing vapor lock at high temperatures; 3. It does not cause corrosion to metal or rubber. The method for changing brake fluid is: 1. Park the vehicle on level ground, turn off the engine, open the hood, and drain the fluid from the reservoir; 2. Use a funnel to refill the reservoir with new brake fluid; 3. Use a jack to lift the vehicle and remove the tires, starting with the rear wheels; 4. Remove the rubber dust cap from the brake caliper; 5. Use a wrench to loosen the bleed screw and attach a rubber tube to it, connecting it to a drain bottle; 6. Press the brake pedal inside the car while observing the fluid drainage until the fluid level in the reservoir under the hood reaches the lower limit; 7. Start the vehicle and perform a brake test in a relatively safe area.
