Can I Change the Brake Fluid Myself?

You can change the brake fluid yourself. Below are the steps for changing the brake fluid on your own: 1. Before changing the brake fluid, park the vehicle on a level surface and check if the brake fluid level meets the specified mark. If the fluid level is low, analyze the cause and resolve the issue before replacing the fluid. 2. First, use a suction tool to remove the brake fluid from the reservoir until it reaches the bottom. If you don't have a suction tool, you can drain the old fluid from one of the four wheels' brake fluid bleeder valves until the fluid level is low enough. 3. After draining the reservoir, refill it with new brake fluid. While bleeding the system, periodically check the fluid level in the reservoir and top it up as needed to prevent air from entering the brake system. 4. The brake fluid replacement process does not require starting the engine but needs two people: one to press the brake pedal and the other to bleed the system. 5. When opening the bleeder valve to drain the old brake fluid, ensure it is collected in a container to avoid spillage or splashing onto other parts. 6. Finally, close all bleeder valves, open the fill port, and add new brake fluid to the specified level.
You can replace the brake fluid yourself, but you must be extremely cautious as it involves the safety of the braking system. Any mistake could lead to brake failure, which poses significant risks. I recommend that only experienced individuals attempt this task. You'll need a jack to lift the car securely and prepare specialized tools such as a fluid drain pan. Ensure the new brake fluid matches the original factory specifications, either DOT3 or DOT4. Don’t forget the bleeding process, which requires an assistant to pump the brakes to remove air and prevent bubble formation. The entire process is time-consuming, taking about an hour. Replacing brake fluid every two years prevents fluid degradation and moisture absorption, improving braking performance. If you lack the tools or experience, it’s safer and more reliable to visit a professional shop. Safety should always come first—don’t take risks just to save money, as brake failure is a serious hazard.
