Why does my brake fluid need to be changed?
Brake fluid must withstand operating temperatures of up to 230oC but over time absorbs water which boils at 100oC. As the water boils, it turns to compressible vapour which means you won't be able to brake as efficiently.
What happens if it's not changed?
If too much moisture builds up, the brake fluid can boil while you're braking, seriously affecting performance. It can cause the brakes to fail. A spongy feel to the brake pedal shows you this has started to happen.
What will be done and when is it recommended?
We check the level and look for leaks. We drain the system and fill it with new brake fluid. We test the system and record it in your service book. The interval for the change of brake fluid differs with manufacturer but an average is every 2 years.
