Flush brake fluid every 2 years
Brake fluid absorbs moisture and lowers the boiling point over time.
The expert tip
- Brake fluid is hygroscopic — it soaks up moisture
- Old fluid boils sooner and corrodes the system
- Flush every 2 years with the correct type (DOT 3/4/5.1)
- Never mix DOT 5 silicone with others
