If your brake fluid is hygroscopic then it means that is will absorb water/moisture from the air and it can effect your boiling point and your brakes may fail at high speeds.

Is brake fluid hygroscopic?
Yes it readily absorbs moisture.
WHAT PARTICULAR TYPE OF BRAKE FLUID IS NOT HYGROSCOPIC AND DOES NOT ABSORB MOISTURE?
DOT 5 is silicon based and will not absorb moisture.
When is the ideal time to change your brake fluid?
Brake fluid must be changed every two years at most. Since it is hygroscopic--that is, it absorbs moisture/water over time. with our tropical climate, this problem is exacerbated. Fresh brake fluid helps resist brake fade and give better brake feel and modulation.
Can Brake fluid absorbs water?
No, the fluid cannot absorb water but you can get water in your brake system and that would be bad. --Most brake fluids used today are glycol-ether based. Glycol-ether brake fluids are hygroscopic (water loving), which means they absorb moisture from the atmosphere under normal humidity levels. Racing brake fluid may be synthetic and not have this problem, but in the everyday world, brake fluid does absorb water.
When do you refill the brake fluid in your car?
It is recommended that brake fluid be added if it is low. We usually see marks on the dipstick (on vehicles that have them) or on the side of the brake fluid reservoir. The marks will usually say "full" or "low" and can be used as indicators as to if and when to add brake fluid. There is one more thing. Manufacturers and service professionals usually recommended that brake fluid be changed every two years. Brake fluid is hygroscopic, which means it absorbs water. If brake fluid absorbs atmospheric moisture over a period of time, the boiling point of the fluid will drop. Under extreme conditions, the fluid could boil causing catastrophic failure of the brakes.
What is meant when a fluid is hygroscopic?
It absorbs water.
How often should brake fluid be changed in 2004 f-150 ford truck?
Most car makers recommend that the brake fluid be changed every two years. The make/model of the vehicle is not an issue, it is just that brake fluid has a "life span" of about 2 years once it is in use. Brake fluid is "hygroscopic", which means it absorbs water from the air, so after about two years of use it needs changing.
What are the symptoms of contaminated brake fluid?
Generally contaminated brake fluid is very dark and grimy looking. It also may cause a spongy brake petal, but not always. If you have reason to believe that your brake fluid is contaminated, you should definitely have it changed. If there is more than 3% water in your brake fluid, you run the risk of super heating the water causing one or more of your brake lines to explode, which apart from being incredibly dangerous is also tremendously expensive to repair. Brake fluid is very hygroscopic, and when exposed to air, it readily absorbs water.
When polyglcol brake fluid is said to be hygroscopic it means that the fluid wil easily do what?
It means that the brake fluid absorbs water. Most all brake fluids you use in you're vehicles, automotive or otherwise will absorb water from the atmosphere right through the brake systems metal and rubber parts. You should change or at the very least, inspect your brake fluids yearly. As water is absorbed into the system, the boiling point lowers and the fluid can do very nasty things to your brake lines, abs systems and master cylinder parts.
Is silicone brake fluid hygroscopic?
No, but it's also completely incompatible with the stuff in your car now and it's very expensive. As to the fluids that don't require you to flush the brake system two or three times when changing over, try a good brand-name DOT 4 fluid.
How often should one replace their brake fluid?
The best advice is to follow the manufacturer's service interval recommendations. Fluid should also be changed if it appears dirty (new fluid is nice clear yellow) or the cap has been loose on the reservoir (as brake fluid is hygroscopic and will absorb moisture from the air, rendering it ineffective). Find a mechanic you trust and follow their recommendations.
What is the effect of brake fluid on plants?
Typically brake fluid is a petroleum base, so one drop won't typically hurt them but if emersed it will kill them.
