You can replace the brake fluid yourself. Brake fluid, also known as hydraulic brake fluid, functions to transmit pressure within the vehicle's braking system, enabling the wheel brakes to perform the stopping action. The steps to replace brake fluid are as follows: 1. Park the vehicle on level ground and turn off the engine, then open the hood and extract the old fluid from the reservoir; 2. Use a funnel to fill the reservoir with new brake fluid; 3. Jack up the vehicle and begin by removing the rear wheels; 4. Remove the rubber dust caps on the brake calipers; 5. Loosen the bleeder screws with a wrench, attach a rubber hose, and connect it to a drainage bottle; 6. Have someone press the brake pedal inside the car while you observe the fluid drainage until the fluid level in the reservoir drops to the minimum mark; 7. Start the vehicle and test the brakes in a safe area.

I've changed the brake fluid myself a few times, and I think it's doable with some basic DIY skills and the right tools. You'll need new brake fluid, tubing, a syringe, and a wrench—costing around a hundred bucks. First, park the car on level ground and use a jack to lift the wheels for safety. Open the reservoir cap under the hood, connect the bleeding tools, and slowly drain the old fluid from each wheel's caliper. The key is bleeding air bubbles—it requires two people: one repeatedly pumps the brake pedal inside the car while the other watches for bubbles to clear. After bleeding, top up with new fluid and take a short test drive to check brake firmness. Patience is crucial to avoid air pockets that could cause brake failure. I learned from online tutorials, but beginners should start with simpler maintenance tasks first. It saves on repair costs and builds knowledge, though the risks are real—if done wrong, faulty brakes can be dangerous. That’s why I change the fluid every 2-3 years for safety.

Honestly, I don't recommend changing brake fluid by yourself—it's the lifeblood of your vehicle, and any mistake can lead to dangerous situations. A friend of mine didn't fully bleed the air during a DIY attempt and nearly rear-ended another car, ending up spending a fortune on repairs. Now, I always go to authorized 4S shops or certified repair centers. Professional technicians have the right tools and expertise to avoid mistakes. They use specialized equipment to thoroughly purge air and ensure smooth hydraulic performance, while I only pay a few hundred bucks. Maintaining the brake system is crucial—old fluid absorbs moisture, corrodes components, and increases stopping distance, especially after rainy seasons or long trips. DIY saves little money but carries huge safety risks. I'd rather have it checked every two years by a reliable shop. Safety always comes first—don't gamble your life to save a few bucks.

My first attempt at changing brake fluid was quite daunting. I was excited while preparing the tools and fluid, but the actual operation turned out to be tricky. The first step was to buy the correct type of new fluid, and I made a mistake once, requiring a return and exchange. Then, locating the correct caliper position to bleed the fluid was challenging, and doing the bubble purging alone was difficult—I ended up making a mess with spilled fluid. Worried about air getting in and causing soft brakes, I paused halfway and sought help from a repair shop. Tutorials made the steps seem simple, but in reality, it was time-consuming and prone to errors, especially since each wheel needed individual attention to ensure balance. For beginners wanting to try, I recommend learning from online videos or getting guidance from experienced drivers, taking safety tests step by step. Brake fluid should be replaced every 20,000–30,000 kilometers or every two years, as proper maintenance extends component lifespan.
