How many liters of brake fluid are needed for a LANGDONG brake fluid replacement?
2 Answers
Replacing the brake fluid for a LANGDONG requires 1L. The replacement interval and precautions for brake fluid are as follows: Brake fluid replacement interval: Brake fluid generally needs to be replaced every 40,000 kilometers or every 2 years. During normal driving, if you notice the brake pedal feels soft, you should use a brake fluid tester to check if the brake fluid has deteriorated and determine whether replacement is needed. Precautions for replacement: During replacement, it is essential to use brake fluid of the same grade as originally specified for the vehicle. The brake fluid grade is indicated on the brake fluid cap. For example, if the original specification is DOT4, only DOT4 grade brake fluid should be used. Mixing different grades can severely affect brake fluid performance. Additionally, when adding new brake fluid, make sure to thoroughly clean out the old brake fluid before adding the new one.
Last time I changed the brake fluid for my Elantra by myself, the whole process was quite interesting. The required amount is about 0.7 liters, but I usually buy a 1-liter bottle of DOT4 fluid and keep the remainder for next time. Before changing the fluid, make sure the car is parked stably, use a wrench to loosen the drain screw, have one person press the brake while another watches the fluid coming out of the hose to drain all the old fluid. Brake fluid is highly hygroscopic, so it needs to be replaced every two years or after driving 40,000 kilometers; otherwise, the brakes will become soft. Doing it yourself saves some money, but be careful not to let air enter the system, or the brakes won't work. It takes about half an hour to complete, with just a basic tool set. Remember to wear gloves, as the fluid can corrode the skin.
