Does a car need brake fluid replacement?
2 Answers
Automobile brake fluid needs to be replaced. Below are the precautions for brake fluid replacement: 1. The replacement interval for brake fluid can be appropriately advanced or delayed based on vehicle usage, mileage, driving conditions, and brake responsiveness. Since new cars come with factory brake fluid of better quality, the service period can be extended slightly, generally requiring replacement after about 5 years. For normal vehicles, the replacement interval is approximately 2-3 years or around 50,000 kilometers. 2. When replacing brake fluid, do not opt for cheaper options; always choose high-quality brake fluid. Issues with brake fluid can significantly impact braking performance. 3. Automobile manufacturers typically recommend replacing brake fluid every 2-3 years because brake fluid is an alcohol-based oil product. Over time, moisture from the air can permeate into the brake fluid. If there's excessive moisture in the brake fluid, continuous braking could cause the brake system to overheat, potentially leading to brake fluid boiling and resulting in the serious consequence of brake failure.
From my experience, changing brake fluid is absolutely necessary for cars! Having driven for decades, I know brake fluid is as vital as blood. Over time, it absorbs moisture from the air, lowering its boiling point, which can degrade braking performance or even cause failure—extremely dangerous in emergencies. Manufacturers generally recommend replacement every two years or around 30,000 kilometers; specifics are in the owner’s manual. During every service, I check the fluid level and moisture content—a simple test with a dedicated pen tool tells if it’s time for a change. Always use high-quality DOT4 fluid to avoid corroding the hydraulic system; don’t compromise safety to save a few bucks. Remember, the braking system is directly tied to the vehicle’s safety—regular maintenance ensures peace of mind on the road.
