How often should the brake fluid of Wuling Hongguang be changed?

Generally, the brake fluid should be completely replaced every two years or 40,000 kilometers. Although the replacement cycle of brake fluid is relatively long, if it is not replaced in time, the brake fluid will become turbid, the boiling point will decrease, and the effect will deteriorate. Over time, it will damage the entire braking system and even lead to brake failure. The introduction of brake fluid is as follows: 1. Introduction one: Brake fluid, also called brake oil or hydraulic brake fluid, its English name is Brake Fluid, which is an indispensable part of the braking system. In the braking system, it acts as a medium for force transmission. Because the liquid cannot be compressed, the pressure output from the master cylinder will be directly transmitted to the sub-cylinder through the brake fluid. 2. Introduction two: Hydraulic brake fluid is a functional liquid used in the hydraulic braking system to transmit pressure to stop the rotation of the wheels. Its working pressure is generally 2MPa, and the high pressure can reach 4~5MPa. All liquids have the characteristic of being incompressible. In a sealed container or a pipeline filled with liquid, when the liquid is under pressure, the pressure will be quickly and uniformly transmitted to all parts of the liquid.
I've been driving a Wuling Hongguang for several years. At first, I didn't know how often the brake fluid needed to be changed. Later, during a maintenance check at around 40,000 kilometers, the mechanic inspected it and suggested replacing it because the boiling point was too low. That's when I learned that brake fluid absorbs moisture over time, which can affect braking performance and potentially lead to longer stopping distances—a serious safety hazard. Now, my routine is to change it every two years or 40,000 kilometers, depending on usage intensity. For example, if you frequently drive in congested city traffic where moisture absorption is higher, you might need to replace it sooner. I recommend paying attention to how the brakes feel; if they feel soft or less responsive, it's likely time for a change. In short, as a car owner, don't skimp on this expense—safety comes first. Just take it to a reliable repair shop. Every time after a change, the brakes feel much sharper, and it gives me peace of mind.
From my experience, brake fluid maintenance should never be taken lightly—it's like the lifeline of a vehicle. For popular models like the Wuling Hongguang, manufacturer manuals typically recommend replacement every two years or after 40,000 kilometers, whichever comes first. However, I've noticed many drivers neglect this schedule, leading to moisture buildup that degrades braking performance and, in severe cases, could cause failure during emergency stops. It's wise to adopt a routine testing habit, using a simple tester to check the fluid's boiling point. Don't wait until you feel the brakes lagging; preventive maintenance is safer and cost-effective. A professional shop can flush the system and refill it with fresh fluid in just minutes. Remember, in humid climates or frequent mountain driving, shorten the maintenance interval.
