Does the car's brake fluid need to be replaced?

[VonJulianna]

Car brake fluid needs to be replaced. Car brake fluid is the liquid used in hydraulic braking systems, which must not undergo chemical reactions, be unaffected by high temperatures, and not cause corrosion, softening, or swelling to metals and rubber. The commonly used types are DOT3, DOT4, and DOT5. Characteristics of car brake fluid: 1. The freezing point of car brake fluid is relatively low, ensuring good fluidity in low-temperature conditions; 2. The boiling point of car brake fluid is relatively high, preventing vapor lock in high-temperature conditions; 3. The quality of car brake fluid changes minimally during use, avoiding corrosion to metals and rubber.

After driving for over a decade, I've deeply realized how crucial it is to regularly change brake fluid. Brake fluid gradually absorbs moisture, lowering its boiling point. Under high temperatures, the liquid can boil, potentially causing brake failure—a serious matter. A close acquaintance of mine neglected to change it and experienced spongy brakes during a downhill drive, nearly causing an accident. Experts recommend replacing brake fluid every two to three years or around 20,000 kilometers, depending on the car's manual. Changing it yourself isn't difficult—just buy a bottle of DOT4-grade brake fluid and have a professional or dealership technician handle it to avoid air entering the system. Safety isn't something to take lightly; this small maintenance cost of a few hundred dollars can prevent many potential accidents. I always have technicians test the moisture content—if it exceeds the limit, I replace it immediately. Remember, car maintenance isn't about saving money—it's about saving lives.

As a cost-conscious car owner, I believe changing brake fluid is an economical and efficient choice. If not replaced, the increased moisture content in the brake fluid can corrode metal components such as brake calipers or ABS pumps, potentially costing thousands to repair. In contrast, new brake fluid only costs tens to a hundred yuan, with labor bringing the total to around three to five hundred. I change it every two years to avoid major repair hassles. Comparatively, when the car reaches its end-of-life, a well-maintained braking system extends its overall lifespan and maintains higher resale value. I make it a habit to refer to the vehicle's manual and follow recommended intervals—never skimping on safety investments, which always pay off in savings and peace of mind. Establishing regular maintenance routines also allows for simultaneous checks on tires and brake pads, ensuring smooth and safe travels with multiple benefits.

When I first learned to drive, my instructor repeatedly emphasized the importance of regularly changing the brake fluid, otherwise the braking performance would deteriorate. Simply put, brake fluid is like the blood in a hydraulic system. Over time, it absorbs moisture and becomes diluted, making the brakes less responsive in emergencies. I follow the manual's recommendation to change it every two years or 30,000 kilometers. Usually, at the repair shop, they test it with a test pen, and if the color indicator exceeds the standard, it's time for a change. Beginners don't need to worry about complex knowledge; maintaining basic habits is sufficient. This maintenance is simple yet crucial. Don't wait until the brakes fail to take action. Start with good car care habits from the beginning—it saves money and ensures safety, giving you peace of mind every time you drive.

After starting a family, I pay more attention to safety details in my car. If brake fluid isn't replaced and absorbs too much moisture, braking distance increases, posing significant risks when driving with children. I insist on changing it every two years, with the mechanic checking the boiling point – if it exceeds limits, we replace it immediately. Moisture issues affect the hydraulic system and may lead to brake failure. I've read reports of people skipping this maintenance to save effort, resulting in rear-end collisions on highways. So don't risk safety for small savings – scheduled maintenance is a responsibility that safeguards your family's wellbeing. The money spent is worthwhile for peace of mind during travels. This item is part of routine maintenance, and forming the habit is easy.
