Water in the brake fluid leads to corrosion. Water may get into the fluid from the humidity in the air whenever the cap is removed from the reservoir. It can also penetrate the microscopic pores of the rubber hoses in the brake hydraulic circuit. Although there are corrosion inhibitors in the fluid, they wear out over time—up to 90 percent in as little as three years. The more depleted they are, the less moisture it takes to cause corrosion damage.
