Brake fluid is hygroscopic, meaning it has the ability to absorb moisture from the air. This property is important for several reasons:1. **To keep the brake fluid viscosity as high as possible**: Brake fluid needs to maintain a high viscosity (thickness) to ensure proper lubrication and hydraulic performance in the braking system. The absorption of moisture can lower the boiling point of the brake fluid, which can lead to vapor lock and brake failure under high temperatures.2. **To prevent local freezing in the brake system**: In colder climates, moisture in the brake fluid can freeze, which can cause the brake lines to expand and potentially lead to brake failure. By being hygroscopic, brake fluid helps to minimize the amount of moisture that can enter the system, reducing the risk of freezing.3. **To prevent rust in the brake system**: Brake fluid can act as a rust inhibitor, protecting the internal components of the brake system from corrosion. The absorption of moisture helps to neutralize the corrosive effects of water.The statement "Brake pedal feel is improved if there's a little water in the brake system" is incorrect. Even a small amount of water in the brake system can significantly affect brake performance and safety. Therefore, it is crucial to keep brake fluid free from moisture contamination.
