Why it matters: Brake fluid absorbs moisture over time, which lowers its boiling point and can corrode brake components from the inside. That's why the interval is time-based (years), not mileage-based.
Changing brake fluid means bleeding the system — doable at home with a helper or a one-man bleeder, but most people have a shop do it ($80–150). A moisture test strip can tell you if it's due.
