Why brake fluid goes bad?

In nature, brake fluid is hygroscopic, which means moisture is absorbed by it from air. The brake liquid is kept in a restricted system but still, a tiny volume of moisture can find its way inside the structure and get mingled with the liquid.

This can grow the water content in the brake fluid over time. What’s worse, a pretty small volume of moisture can contaminate the fluid and lessens its effectiveness. Various issues could cause the contamination, including broken seals, holes in the rubber hoses, or if the cap of the brake fluid is not properly closed.
