Brake fluid is a vital component of automotive brake systems – it uses hydraulic pressure to transfer pressure (amplified) from the brake pedal to the calipers that press the brake pads against the rotors to slow down your vehicle. Brake fluid requires regular replacement – typically every 2 years or 20,000 miles. Working under high temperatures, over time the fluid loses its chemical and mechanical properties. Increased water content further accelerates this deterioration. Water content?! Yes, brake fluid is highly hygroscopic – it absorbs moisture from the environment. Over time it can absorb so much water as to become less effective, and in severe cases (because water boils off at a lower temperature than the working temperature of the fluid) the water may boil off causing braking problems.
