How does brake fluid get contaminated?
One way that brake fluid becomes contaminated is when moisture is absorbed by the brake fluid through rubber brake lines. This moisture will break down the brake fluid and cause rust in the brake system.

Final Thoughts
If your brake fluid is leaking (especially internally), this could mean a problem NOT only with worn out or damaged lines and other braking components, but it probably created some other problem inside your vehicle. Low brake fluid could also mean that your brake pads need to be checked and may be replaced.
What is brake fluid?
Brake fluid is a “hydraulic fluid” which moves the components in your vehicle’s braking system. There are four types of brake fluid sold; all are regulated by the Department of Transportation (DOT).
Why is it important to check brake fluid?
It’s especially important to check your brake fluid periodically if you live in a mountainous region or tow heavy equipment for extended periods. Since more heat is generated under heavier braking conditions, it’s possible that your brake fluid can exceed its boiling point and form vapor bubbles, which can cause brake failure.
Why is my brake pedal harder to depress?
Noticeable change in pedal pressure. Contaminated brake fluid is just one of the reasons why the pedal is either harder or easier to depress. You could have a leak through a brake line. You could need new brake pads and hardware. Whatever the reason, fix the problem to be safe.
Why does brake fluid deteriorate?
That moisture causes the fluid to deteriorate because the boiling point of brake fluid can be severely reduced when it is ‘wet’ (i.e.
What does it mean when your brake light goes on?
Brake Warning Lights. When your ABS or Brake System light goes on, get your brakes and brake fluid checked ASAP. An illuminated light often means your fluid levels are low, probably due to a leaking brake line, which allows contaminants to enter and pollute the brake fluid.
How often should I change brake fluid?
Most “regular drivers” should be changing brake fluid every one to two years, (check your owner’s manual). If you’re not changing brake fluid when recommended, you risk brake failure due to contamination, which leads to deterioration.

Why is it important to maintain brake fluid?
Maintaining your car’s brake system is hugely important to vehicle safety. Brake fluid helps transfer the pressure from a driver’s foot to the brake pedal to stop the vehicle . Its levels must remain full and in good condition. Low fluid levels or fluid in poor condition will not let the brakes help you stop the car. Brakes are usually serviced by a mechanic, but sometimes you need to bleed brakes to remove trapped air and flush out old or contaminated fluid. This means you’ll also need to return the brake fluid reservoir to acceptable levels — most designs include a “min” and “max” line for reference.

Is brake fluid poisonous?
While sitting in a car, it absorbs heavy metals that make it poisonous when ingested by humans or animals. Even new, uncontaminated brake fluid left in a jar that’s been opened tends to absorb enough water to dangerously reduce its boiling point, further increasing its flammability.
