Every driver knows that brakes are one of the most crucial components of your vehicle, and are absolutely vital to keep you safe on Carroll roads. That’s why it’s so important to keep your brakes in top condition and don’t let them get too worn down. But how can you do this? One way to ensure they continue to function properly is by checking the brake fluid regularly.



Here you can learn how to check brake fluid from the helpful service team at Macke Motors, Inc., and if you have questions, contact us. Our team will make it possible for you to become a DIY handyman when it comes to maintaining your vehicle’s condition with our selection of tips and tricks.

What is Brake Fluid?

Brake fluid is a hydraulic liquid that helps lubricate your brake pedal and braking system and keeps it from corroding. The brake fluid in most vehicles is glycol-ether based. You may also find silicone-based (DOT-5) and mineral oil-based (LHM) brake fluids at parts stores around Fort Dodge. You can order brake fluid online with Macke Motors, Inc., and your owner’s manual will stipulate which brake fluid should be used on your vehicle.

What Color is Brake Fluid?

So, what color is brake fluid anyway? Fresh brake fluid is nearly clear with a slight yellowish tint to it. Of course, over time, as you drive around Lake View using your braking system, it wears down and changes color. If your brake fluid looks dark and oil-like, it has picked up dirt and debris, which can negatively affect the performance of your brakes.

Checking Brake Fluid in Three Easy Steps

  1. Find your vehicle’s brake fluid reservoir on or near the master cylinder. If you can’t find it, check your owner’s manual or research it online.
  2. Outside the brake fluid reservoir, you should see “minimum” and “maximum” lines. Check the brake fluid to see how full it is. If the brake fluid is closer to the minimum line, you need new brake fluid. You can schedule service online at Macke Motors, Inc. or do it yourself.
  3. Check the color of the brake fluid. If it’s deep brown or black and looks more like engine oil, you need a brake fluid flush immediately.

How Often Should You Replace Brake Fluid?

The service team at Macke Motors, Inc. recommends checking brakefluid every time you change the oil or at least once per year. Brake fluid can last up to four to five years but varies depending on the type of vehicle, your driving habits, and driving conditions in Lake City.
