How Often Should Brake Fluid Be Replaced in a Car?
2 Answers
It is recommended to replace the brake fluid every two years or 40,000 kilometers. Whether the brake fluid needs to be replaced mainly depends on its water content. It is advisable for car owners to regularly use a brake fluid tester to measure the moisture content in the brake fluid and determine if replacement is necessary. Below is some relevant information about brake fluid: 1. Brake fluid has hygroscopic properties. If it is not replaced for a long time, the safety factor of driving will decrease. 2. If you notice that the braking feel has become significantly softer or even feel that the car is not stopping properly, it is time to check whether the brake fluid has oxidized or deteriorated. If such conditions exist, the brake fluid should be replaced promptly to avoid potential hazards.
As a veteran driver with over a decade of experience, I believe brake fluid replacement is something you really can't take lightly. Brake fluid absorbs moisture, and over time its boiling point decreases, making it prone to boiling under high temperatures and leading to brake failure. The standard replacement interval is every two years or 40,000 kilometers, but in reality, it depends on your driving habits. For example, I frequently encounter traffic jams during my daily commute in the city, using the brakes more often and accumulating moisture faster, so I insist on replacing it every three years or 30,000 kilometers. In the humid and hot southern regions, you need to be even more diligent. It's a good habit to regularly visit a repair shop and use a test pen to check the boiling point—it's inexpensive, costing just a few dozen yuan. You can also do it yourself, but bleeding the air can be tricky, so going to a professional shop is more convenient and safer. Remember, the braking system is a matter of life and death, so never delay or skimp by using cheap, low-quality fluid.
