How often should the brake fluid in the Baojun 510 be changed?

The brake fluid in the Baojun 510 should be changed every 2 years or 40,000 kilometers. Symptoms indicating the need for a brake fluid change include: 1. The brake warning light alerts or flashes during emergency braking or continuous braking; 2. The braking distance becomes noticeably longer than before during emergency braking; 3. The brake pedal feels soft or lacks force when pressed; 4. The braking force feels inconsistent, sometimes light and sometimes heavy. The Baojun 510 is a compact 5-door, 5-seat SUV with dimensions of 4220mm in length, 1740mm in width, and 1615mm in height, with a wheelbase of 2550mm. It is equipped with a 1.5L naturally aspirated engine and a 6-speed manual transmission, delivering a maximum power of 73 kW and a maximum torque of 135 Nm.

I'm a seasoned driver with over 20 years of experience and regularly maintain my Baojun 510. The general manual recommends replacing brake fluid every 2 to 3 years or every 40,000 kilometers. However, the actual interval depends on driving habits. For instance, in areas with frequent highway driving or damp, cold weather, the fluid absorbs moisture faster, lowering its boiling point, which can make the brakes feel sluggish or spongy—extremely dangerous. I remember once when I delayed replacing it, I almost had an accident going downhill on a mountain road. That's why I insist on having the moisture content tested every two years at the repair shop. If it exceeds 3%, it must be replaced. I also take the opportunity to check the brake pads and hose wear to avoid minor issues. Road safety comes first—don’t skimp on this expense.

As an automotive mechanical enthusiast, I have done considerable research on braking systems. The Baojun 510 uses DOT4-type brake fluid, which has hygroscopic properties. Over time, it absorbs moisture, lowering its boiling point and forming air bubbles that affect brake response. The manufacturer recommends changing the fluid every two years or 40,000 kilometers, but in humid climates, it may need more frequent replacement. You can purchase a simple test pen to check water content at home and replace it promptly if it exceeds the standard. When changing the fluid, it's crucial to bleed the air from the system, as residual air bubbles can lead to brake failure. Keeping the fluid fresh not only benefits the lifespan of the brake pump but also enhances overall handling. Don't forget to lubricate the related components.

I'm a practical user who prefers saving money, and driving the Baojun 510 for commuting is cost-effective. The brake fluid replacement manual recommends changing it every two years, but I've managed to stretch it to three years without issues, provided I don't speed or frequently drive on mountain roads. A money-saving tip is to first visit a repair shop for a moisture test with a tester pen—if the readings are normal, you can delay the change. The cost of replacing the fluid is just a few hundred yuan, much cheaper than repairing accident damage. Also, check the brake disc thickness and whether the fluid has darkened. Keeping it clean extends part longevity. If the brakes feel spongy while driving, act promptly—don’t let minor issues escalate into major problems.
