When it comes to car maintenance, most drivers know to get regular oil changes and tyre checks - but there's one crucial fluid that often gets overlooked - brake fluid. 

A brake fluid flush is an essential part of maintaining your vehicle’s braking system, and skipping it can lead to reduced performance, expensive repairs, or even safety risks on the road.

What is Brake Fluid and What Does It Do?

Brake fluid is a hydraulic fluid that plays a critical role in your braking system. When you press the brake pedal, the fluid transfers that force through your brake lines and onto the brake pads and rotors, helping you stop quickly and safely. Without clean, high-quality brake fluid, your brakes won’t function properly.

Why Brake Fluid Needs To Be Flushed

Over time, brake fluid can become contaminated with moisture, dirt, and debris. Brake fluid is hygroscopic, which means it absorbs moisture from the air. Even a small amount of moisture can lower the boiling point of the fluid, which increases the risk of brake fade - especially during hard braking or downhill driving. Contaminated brake fluid can also cause corrosion inside the brake lines and calipers, leading to premature wear and costly repairs.

A brake fluid flush involves removing the old, contaminated fluid from the system and replacing it with fresh, clean fluid. This helps maintain optimal braking performance and extends the life of your braking components.

Signs You May Need a Brake Fluid Flush

Here are a few common signs that it might be time for a brake fluid flush:

• Spongy or soft brake pedal – This could mean there’s air or moisture in the lines.

• Delayed braking response – If your car isn’t stopping as quickly as it used to, the fluid could be degraded.

• Brake warning light – Some vehicles have sensors that detect brake fluid issues.

• Dark or dirty fluid – Clean brake fluid is usually clear or light amber. If yours looks dark or sludgy, it’s time for a change.

How Often Should You Flush Brake Fluid?

Most manufacturers recommend flushing the brake fluid every 2-3 years or 30-40,000 km, but this can vary depending on the make and model of your vehicle and your driving conditions. For example, if you regularly drive in hilly areas or tow heavy loads, you may need more frequent flushes. Always refer to your vehicle’s logbook or speak to a qualified mechanic - such as those at Pearson Automotive, for the right service schedule.
