When to Replace Brake Fluid – Common Signs & Symptoms

Why is brake fluid important?

Brake fluid is a vital fluid which allows your brakes to function properly. It is a hydraulic fluid, which means it cannot be compressed. This means it can transfer force into pressure, which allows your braking system to work properly. When the brake pedal is pressed, the brake fluid is used to create hydraulic pressure. This pushes the brake pads against the rotors and causes your car to slow down or stop.

Without brake fluid, your braking system will not be able to generate pressure and stop. For this reason, it is important to routinely replace brake fluid and immediately repair any leaks that occur. Old or leaking brake fluid can affect the safety of your vehicle and increase your stopping distance.


How often should brake fluid be replaced?

Over time, brake fluid can lose its hydraulic properties. This is due to air, water and other contaminants that can find their way into your brake lines. For this reason, it is important that your car’s brake fluid is routinely changed.

Most manufacturers will recommend that you get your brake fluid changed once every 40,000 km or two years. This will ensure that your brakes are able to continue functioning properly.


Symptoms of brake fluid due for replacement:

  • Brown or black colour – You can examine the levels and cleanliness of your brake fluid via the brake fluid reservoir. The darker the colour, the dirtier it is. Brown or black fluid should be replaced as soon as possible.
  • Increased stopping distance – As brake fluid becomes dirtier, it will slowly lose its ability to slow your car down. If your car is taking longer to stop than normal, we recommend that you examine the brake fluid.
  • Spongy brake pedal – Contaminants such as air in the brake fluid can cause your brake pedal to become soft or spongy to press.
