What is the method for changing brake fluid?

[NathanLynn]

Open the car hood, locate the brake fluid reservoir, and remove the reservoir cap to inspect the quality of the brake fluid. Use a syringe to extract all the old brake fluid from the reservoir, then refill it with new brake fluid. During the extraction process, avoid splashing the fluid on yourself to prevent corrosion from the brake fluid. Other methods for changing brake fluid are as follows: 1. Locate the two brake lines on the master cylinder in the engine compartment. Use a line wrench to loosen them until brake fluid begins to flow out. Once the reservoir is empty, tighten the lines. 2. Refill the brake fluid reservoir, lift the vehicle, and have one person sit inside to pump the brake pedal several times and then hold it down. Another person underneath the vehicle should use a wrench to loosen the bleeder screw on the brake caliper, allowing brake fluid to drain. Follow the farthest-to-closest principle: bleed the left rear, right rear, right front, and left front calipers in sequence. 3. Lower the vehicle, refill the reservoir, lift it again, and repeat the bleeding process for all four calipers in the same order. Once completed, tighten all bleeder screws and check for leaks to ensure a complete brake fluid replacement.
