Brake fluid is hygroscopic, which means it absorbs moisture over time, reducing the temperature at which the fluid boils. This could result in increased stopping distances, reduced braking efficiency and even brake failure.
Brake fluid must withstand operating temperatures of up to 230°C. Over time, the fluid absorbs water, making it less effective.
If too much water is absorbed, the brake fluid can boil while the brakes are being used. This seriously affects braking performance and can cause the braking system to fail. A spongy feel to the brake pedal shows this has started to happen.
Brake fluid must be replaced at when your car is three years old, and every two years after that, irrespective of the mileage.
During a brake fluid change we check the level and look for leaks. We then drain the system and fill it with brake fluid that meets our high standards. We test the system and record it in your service book. Old brake fluid is disposed of responsibly.
