Here are the steps to replace brake fluid: 1. First, ensure the vehicle is turned off and open the brake fluid reservoir cap. Use a syringe to extract all the brake fluid inside until the reservoir is empty. 2. Then, pour new brake fluid into the reservoir (1-2L), with the exact amount depending on the reservoir's capacity. 3. Use a lift or jack to raise the bottom of the car. 4. Locate the bleeder screw on the brake caliper and remove the dust cap from the bleeder valve. 5. Loosen the bleeder screw with a wrench, attach a rubber tube to it, and connect the other end to a drain bottle. 6. Now, start pumping the brake pedal. Pay attention to the color of the brake fluid in the rubber tube. If the color remains dark, it indicates that the old brake fluid hasn't been fully drained. If the color becomes lighter, it means the tire's fluid has been replaced. Stop pumping the brake pedal and reinstall the screw and dust cap (repeat this process for the other three tires). It's best to have one person operate the brake pedal while another observes the fluid color to prevent accidentally draining all the fluid from the reservoir, which could allow air to enter the brake system. 7. Finally, check the brake fluid level. If it's below the minimum mark, add more brake fluid as needed.
