Brake fluid plays a crucial role in the safety of your vehicle by transferring the pressure you apply to the brake pedal to the actual brakes. Without it, your brakes simply wouldn’t function, and as everyone knows, a car without brakes is incredibly dangerous. Even slightly compromised brakes can pose a serious risk.
Brake fluid has a tendency to absorb moisture over time, which can compromise its effectiveness. Brake systems generate high temperatures, and brake fluid is specifically designed to have a high boiling point to prevent it from evaporating. However, when too much moisture builds up, the boiling point is lowered, making the fluid more prone to boiling under heat. This can lead to reduced brake fluid levels, ultimately affecting your vehicle’s braking performance and increasing stopping distances.
In addition to reducing effectiveness, moisture-contaminated brake fluid can lead to corrosion within the braking system. Over time, this can damage components such as the callipers, wheel cylinders, and anti-lock braking systems (ABS). Regular replacement helps to extend the lifespan of these parts and maintain optimal braking performance.
Brake fluid is hygroscopic, meaning it actively absorbs moisture from the surrounding environment, even through microscopic openings in the brake system. This is why regular maintenance is essential to ensure safety.
Your vehicle’s manufacturer will specify how often the brake fluid should be replaced—typically outlined in the logbook service schedule. At Ausmech Mechanical Services, we recommend replacing it every two years as a general guideline. However, it’s equally important to have it checked during each routine service. A professional mechanic can assess the moisture content in the fluid and check for any leaks or other signs of wear that might require earlier attention.
