Brake fluid draws moisture. Moisture is water and water is H2O, ie air
molecules. These accumulate in the fulid and the end result is a steday decline
in brake performance. This why you should never use a opened bottle of brake
fuild for the BEST autocross or racing results. This is ok for normal street
applications. As you might guess the heat cycle action increases condensation,
so when we get our brakes real hot each weekend we hasten this process. That is
why frequent brake bleeding is reccomended.
