When a new car is running for 12 months, its brake fluid may inhale about 2% of the water, and at 18 months the water content can reach 3%, which is enough to reduce the boiling point of the brake fluid by 25%. After a few years, the water content in the brake fluid will probably reach 7%-8%.

Therefore, the vehicle manufacturer's recommendations for brake fluid replacement should be followed. If the vehicle manufacturer does not provide this indicator, it is best to check the water content in the brake fluid. If the water content is too high, it must be replaced. If it is not checked, it is generally recommended to replace it for 2 years or 40,000 km. Brake fluid replacement intervals in some rain and wet areas in the south should be shorter.

How to change the brake fluid

1. Before replacing, park the vehicle on a level surface and check if the brake fluid level reaches the specified position. If the brake fluid volume is small, analyze the cause and replace the new oil with the fault.

2. Open the oil drain and release the old brake fluid. Note that the old brake fluid should be received by the container. Do not lose or splash it to other parts to avoid any bad phenomena.

3. Check the brake status to analyze the brake system.

4. Try to put the old brake fluid clean. If the old oil is dirty, use the new brake fluid to flush the oil storage tank 1-2 times until the flushing is clean.

5. Close the oil drain and open the fuel filler to inject new brake fluid to the specified position.

6. Start the vehicle to test the brakes, then stop to check the brake fluid level, and if necessary, make up the amount.
