Whether we like it or not, the brake fluid can get contaminated at times. Unfortunately, moisture can enter the brake fluid and it will cause it to break down chemically. That means unwanted chemicals will enter the brake fluid and the best thing that you can do at this point is to try and replace it if possible.

What happens when brake fluid is contaminated?

Basically the main issue is that the braking efficiency will not be as good as it has always been. There will be braking problems, not to mention the vehicle will start having lots of rust in the brake lines. While this might not seem like a major problem at first, it definitely becomes one as time goes by. And that’s why you need to make sure that the brake fluid is always clean. A brake fluid flush might be needed in this situation.

This is a thorough cleansing that will remove all the residual moisture and unwanted particles. After you do that, you will have to replace the brake fluid with a fresh, uncontaminated one. Braking problems can appear out of nowhere in a situation like this, so we do recommend to flush the fluid regularly especially if there are signs of contamination.

How do I know if my brake fluid is contaminated?

That’s where the issue lies most of the time, as identifying this is very tricky more often than not. In this case the best thing that you can do is to see whether your brakes are working properly. You can also open up to check the color of the brake fluid. If it’s different from the regular coloring, then that means some sort of contamination took place and you have to deal with that.

What causes dirty brake fluid?

As we mentioned earlier, it can be anything from residual moisture to unwanted particles. Even if water for some reason enters the brake fluid, it will lead to breaking down the molecular structure of the fluid and that on its own can bring in major issues.

Is a brake fluid flush really necessary?

Yes, if you see that the brake fluid is contaminated, a flush becomes pretty much mandatory. The last thing you want is to deal with rust and any other problems that will turn into costly repairs. With this idea you get the best of both worlds and results will be great anyway, which is what matters the most.

Yes, brake fluid contamination might be hard to deal with, but it’s something that we have to consider all the time. It takes a while for us to identify why the brake fluid is contaminated and how to tackle it. But ideally you go to a professional and he will flush the brake fluid, clean things up and replace it with a new one. It’s a great idea for sure, and one that will help you immensely. Just give it a try and you will be incredibly happy with the experience.
