What are the symptoms indicating brake fluid needs replacement?
2 Answers
Brake fluid needs replacement when the following symptoms appear: 1. Brake fluid turns black: When the brake fluid turns black, it indicates the presence of impurities. In this case, it should be replaced promptly to avoid brake fluid blockage, which could affect driving safety. 2. Weak braking: When you feel that the braking is weak, it indicates a problem with the braking system, and insufficient brake fluid can also cause similar issues. In such cases, it is advisable to visit a repair shop or a 4S store for professional inspection and specific analysis. 3. The vehicle is too old: When the car has been driven for a certain number of years, regardless of whether the brake fluid is lacking, it is best to replace it from a safety perspective.
There are some obvious symptoms when car brake fluid deteriorates. I feel the brake pedal is particularly soft when pressed, with a longer travel distance, unlike before when it would stop immediately upon pressing. The braking distance has increased, and braking is especially slippery on rainy days, even with some delay. The fluid color has also changed; originally transparent and bright yellow, it has gradually turned dark brown or become cloudy. The main reason is that the fluid has absorbed moisture, lowering its boiling point and creating bubbles under high temperatures, which reduces braking effectiveness. Sometimes, you might even notice a strange smell or hear unusual noises. It is recommended to check the fluid level and condition every two years or according to the manual's mileage. Never be careless, as delaying may damage the entire braking system, costing a lot to repair and posing a danger.
