Why Brake Fluid Must Be Changed Regularly
Brake fluid is hygroscopic — it absorbs moisture from the air over time. As moisture content increases, the boiling point drops significantly. When the fluid boils under heavy braking, vapour bubbles form and the pedal goes to the floor (vapour lock). Renault requires DOT4 with a dry boiling point of at least 230°C.
How to Check Brake Fluid Condition
- Test strips — dip a strip in the reservoir; colour indicates moisture content
- Electronic tester — measures boiling point directly (most accurate)
- Visual inspection — dark/brown fluid indicates it must be replaced (fresh fluid is amber/clear)
