Well, it isn't "designed" to -- it's designed to do the various things it's
supposed to do and oh by the way it absorbs water.

True, I'm afraid.

The other (and primary) issue is that brake fluid gets *hot* and its
boiling point is drastically lowered by moisture.  If it boils, i.e. some
of it vaporizes in the system, strange things could happen such as the
brakes having a mushy pedal and/or not releasing when you let off the pedal.

Non-synthetic gear oil has a disgusting odor right out of the can...not to
say that it's not a good idea to change the stuff.
