How often should the brake fluid of the Teana be replaced?

The brake fluid of the Teana should be replaced every 2 years. Characteristics of brake fluid: 1. Good viscosity-temperature performance and low freezing point, ensuring excellent fluidity at low temperatures; 2. High boiling point, preventing vapor lock under high-temperature conditions; 3. Minimal quality changes, avoiding corrosion and deterioration of metals and rubber. Taking the 2021 Teana as an example, it is a mid-size sedan with a front MacPherson independent suspension and a rear trapezoidal control arm multi-link independent suspension. It is equipped with a 2.0L naturally aspirated engine, delivering a maximum horsepower of 156 PS, a maximum torque of 197 Nm, and a maximum power of 115 kW, paired with a continuously variable transmission (CVT).
Among the Teana owners we've serviced at our repair shop, it's common practice to replace the brake fluid every 2 years or 40,000 kilometers. This fluid is particularly prone to absorbing moisture, so in humid southern regions, it might need changing even sooner. Just last week, we had a Teana that hadn't had its brake fluid changed in three years, and tests showed excessive water content, making the brakes feel spongy. Don't just go by the mileage—if you frequently drive on mountain roads or sit in traffic jams, the increased brake load accelerates fluid degradation. During maintenance, ask your mechanic to test the fluid with a moisture meter. If it exceeds 3% water content, replace it immediately. The OEM DOT3 specification is perfectly adequate, and you'll notice a firmer brake pedal feel after replacement, especially improving safety in rainy conditions.
I've been driving the seventh-generation Teana for almost four years. The manual recommends changing the brake fluid at 40,000 kilometers, but it actually depends on driving habits. For example, I commute on highways daily, and during the third-year maintenance, the water content test showed it was just at the critical level, so I changed it. My friends in the tuning circle always switch to high-performance brake fluid before hitting the track. The key is to monitor the brake condition: if the pedal travel becomes longer during hard braking, or if you hear a 'hissing' sound when pressing the pedal while parked, these are signs of fluid degradation. Remember to bleed the air when changing the fluid, otherwise, the brakes will feel spongy. Last time, a friend cheaped out and used aftermarket fluid, and three months later, the brake master cylinder started making strange noises—big mistake.
