How often should the brake fluid be changed for the Teana?
2 Answers
Teana brake fluid should be changed approximately every 20,000 kilometers. The brake fluid has a very low freezing point, ensuring good fluidity in low-temperature conditions; the boiling point of automotive brake fluid is extremely high, preventing vapor lock formation under high-temperature conditions; the quality of automotive brake fluid changes minimally during use, avoiding corrosion of metals and rubber. Brake fluid, also known as brake hydraulic fluid or brake liquid, is refined from diesel distillates with the addition of thickeners and antioxidants. There are three types: mineral oil brake fluid, alcohol-based brake fluid, and synthetic brake fluid. In terms of appearance, the Teana adopts Nissan's family-style exterior design, with a front fascia resembling the all-new Sylphy, incorporating Infiniti's dynamic design elements into the body lines, further highlighting the vehicle's fashion and sporty appeal.
Regarding the replacement frequency of brake fluid, as an experienced car owner with many years of experience, I can share that for the Teana model, the brake fluid generally needs to be replaced every two years or every 40,000 to 50,000 kilometers driven. The main reason is that brake fluid gradually absorbs moisture from the air, which over time lowers its boiling point. This can lead to failure during continuous high-intensity braking, such as when going downhill on mountain roads or during emergency braking, resulting in unresponsive performance. My Teana manual clearly recommends a regular check every two years, and if you frequently drive on highways or in humid areas, the interval should be shortened. During routine maintenance, mechanics will test the moisture content of the fluid, and you can also observe the color yourself. If it becomes darker or cloudy, it's time for a replacement. Neglecting this can pose safety hazards. A friend of mine experienced poor braking performance due to prolonged neglect, but it returned to normal after prompt maintenance.
