What are the precautions for brake fluid replacement?

[LaRicardo]

Precautions for brake fluid replacement include completely removing air. The method for replacing brake fluid is as follows: 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 fill the reservoir with new brake fluid; 3. Use a jack to lift the vehicle and remove the tires starting from the rear wheels; 4. Remove the rubber dust cap from 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 reservoir under the hood reaches the lower limit. Brake fluids include castor oil alcohol type, synthetic type, and mineral oil type.
