Brake fluid replacement method: 1. 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 completely empty; 2. Pour new brake fluid into the reservoir. The amount to add depends on the reservoir's capacity; 3. Use a lift to raise the bottom of the car, or alternatively, use a jack; 4. Locate the bleeder screw on the brake caliper and remove the dust cap from the bleeder valve; 5. Use a wrench to loosen the bleeder screw, attach a rubber tube to it, and connect the other end to a drain bottle; 6. Now you can 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 has not been fully drained; 7. Monitor the brake fluid level. If it falls below the minimum mark, additional brake fluid needs to be added.
Changing brake fluid by yourself isn't actually difficult, it just depends on whether you're willing to put in the effort. First, you'll need to prepare new brake fluid, a wrench, a transparent hose, and a clean container. I usually start by having a friend sit in the driver's seat to help pump the brakes while I open the hood and locate the brake fluid reservoir, remove the old fluid, and pour in the new one. Then, remove each wheel one by one, locate the bleeder screw on the brake caliper, attach the hose, and have your friend continuously pump the brakes until the fluid runs clear. Remember to keep adding new fluid while bleeding to prevent the reservoir from running dry. After finishing all four wheels, check the fluid level and the tightness of the lines. The whole process takes about an hour, but the key is to avoid letting air into the system, as it can affect braking performance. Beginners are advised to have a professional do it for safety. Generally, you should change the brake fluid every two years or 40,000 kilometers, but in areas with more rain, you might want to change it sooner.
