Brake fluid protects the metals used in the brake system such as the ABS control valves, master cylinders, calipers and wheel cylinders. The fluid also protects against corrosion when moisture gets in the system, and additives are put in place to help reach this goal.
If you feel that your brake fluid has gone bad, then schedule an appointment at the Chevy Service Center in St. Louis. Our trained technicians will be able to provide a brake fluid exchange and make sure your vehicle’s braking system is in top shape. Schedule your appointment today!
COver time brake fluid absorbs water and gets contaminated, and that could create some issues. One visual clue is having the brake system warning light turning on. The fluid might need to be replaced if there is a burning smell. The brake pedal could also feel harder or softer when pressed. There could also be a squealing, squeaking or grinding noises when the brake pedal is pressed. The car could also pull to one side or the other when braking and the front of your vehicle could also nosedive with strong stops.
Brake fluid is hydroscopic, which absorbs moisture. The more moisture it absorbs, the more likely it will contaminate the brake fluid and drop its boiling point. A lower boiling point will drop the brake fluid’s effectiveness and create more opportunities for the system to overheat. If too much moisture gets in the fluid, it creates vapor pockets, and that could eventually make your brake pedal sink to the floor when pressed with no slow down.
Older brake fluid also gets contaminated with debris. Moisture-tarnished brake fluid can also make metal components to corrode and rust, and those particles land in the brake fluid. Those debris particles can eventually plug up the hydraulic unit. This could hinder your ABS system, which drops braking performance. In worst cases those issues can cause your brakes to fail.
