Brake fluid must withstand operating temperatures of up to 230°C but over time
absorbs water which boils at 100°C. 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 do we do?
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.
How often does it need to be changed?
Every 3 years or 45,000km (whichever comes first)
