Simple Answers from Dave's Complete Auto Service for Council Bluffs: Brake Fluid Service

Question: Why should I flush my brake fluid if my brakes seem to work fine?

Dave's Complete Auto Service Answer: That’s a great question—and a common one. While your brakes might feel fine now, brake fluid is hygroscopic, which means it absorbs moisture over time. That moisture can corrode internal brake components like calipers, master cylinders, and ABS modules. Corrosion leads to leaks, sticking calipers, or even total brake failure.

Moisture also lowers the boiling point of brake fluid. During hard braking (like sudden stops or coming down hills), this can cause the fluid to boil, introducing air bubbles into the system. That results in a soft, spongy brake pedal—and reduced stopping power.

Regular brake fluid flushes help protect your braking system, preserve safety, and avoid costly repairs down the road. Most manufacturers recommend a flush every 2–3 years, but it depends on your vehicle and driving habits.
