Brake fluid is a vital part of your vehicle's braking system, ensuring you can stop safely and efficiently. Yet, many drivers overlook the importance of replacing it regularly. Over time, brake fluid deteriorates, potentially compromising your vehicle's performance and safety. Here’s why routine replacement is essential and how changes in its colour can indicate it’s time for a change.
Why Brake Fluid Degrades
Brake fluid is hygroscopic, meaning it absorbs moisture from the air. This moisture lowers its boiling point, increasing the risk of brake fade during heavy braking. Contaminants and debris can also accumulate, further reducing its effectiveness. If left unchecked, degraded fluid can lead to corrosion in the brake system, causing expensive damage and putting your safety at risk.
How Brake Fluid Colour Changes Over Time
New brake fluid is typically clear or light amber in colour. As it ages and absorbs moisture, it darkens to a brown or even black hue. This discolouration is a clear visual cue that the fluid is contaminated and needs replacing. Checking the brake fluid’s colour regularly can help you stay on top of maintenance before issues arise.
How Often Should You Replace Brake Fluid?
Most manufacturers recommend replacing brake fluid every 2-3 years or as specified in your vehicle’s maintenance schedule. Factors such as driving habits and climate can impact this timeline, so regular inspections are key.
The Bottom Line
Don’t wait for your brakes to feel unresponsive to address your brake fluid. By replacing it at the right intervals and keeping an eye on its colour, you’ll maintain optimal braking performance and safety
