How Often Should You Change Your Brake Fluid?

Your brake system is one of the most important safety features in your vehicle—and brake fluid plays a critical role in keeping it working properly. Over time, brake fluid absorbs moisture, which can lead to corrosion inside the brake lines and reduced stopping power.

So how often should you change your brake fluid? At Joe’s Slinger Service, we generally recommend a brake fluid flush every 2 to 3 years or around 30,000 miles, depending on your driving habits. If you’re often in stop-and-go traffic, tow heavy loads, or drive in the hills around Washington County or surrounding areas, you might need it sooner.

Not sure if your brake fluid needs to be changed? Signs to watch for include:

  • A soft or spongy brake pedal

  • Brake warning lights

  • Reduced braking performance

  • Fluid that looks dark or dirty

We check brake fluid during routine inspections at our shop. If we notice moisture contamination or degraded fluid, we’ll let you know and recommend the best time for a full brake fluid exchange.

Whether you’re in Washington County WI or surrounding areas, our ASE-certified technicians are here to help you stay safe on the road. Schedule your next brake inspection or brake fluid service with Joe’s Slinger Service today!
