When the brake fluid contains too much water and the brake is used frequently, it will generate high temperature. The high temperature is transmitted from the brake caliper to the piston and then to the brake fluid. , The boiling point of water is low, it will become water vapor, water vapor can be compressed, it will cause the braking ability to decline.

Deteriorated or dirty brake fluid can also cause a decrease in braking force. In addition, it will increase the wear of the brake master cylinder and wheel cylinder pistons and shorten their life.

How often should the brake fluid be changed?

Theoretically, it will be replaced in 3 years or 60,000 kilometers. We can extend and shorten the replacement cycle appropriately according to our driving habits and driving conditions.
