Why is Brake Fluid Important?
Brake fluid plays a crucial role in your braking system as it transfers the force created when a driver presses the brake pedal directly onto the wheel hub.
Heat generated under braking, especially under heavier breaking or prolonged breaking, may affect the brake fluid which can only work if it is liquid and not so hot that it has become vapour. Therefore the boiling point that your brake fluid can achieve is critical to efficient braking as temperatures above the boiling point form vapour bubbles in the system, potentially resulting in brake failure.
Whilst regular servicing of your vehicle will include checking the boiling point of your brake fluid, vehicle manufacturers recommend that you change your brake fluid at least every two years if not sooner (check your vehicle handbook for details). Changing brake fluid when recommended prevents brake failure and maintains the boiling point at a safe level.
