What Color is Brake Fluid?

Brake fluid is an essential part of your vehicle’s braking system. When your foot hits the brake pedal, the fluid transfers through the brake cables and applies the necessary pressure on the calipers to push the pads against the brake rotors and bring your vehicle to a stop. Like any other part of your car, you probably don’t think much about it, but the brake fluid and related components need regular maintenance. Read below as our team at Volkswagen of Marion shares what to watch out for in your car’s braking system, including the color of the brake fluid.

What Does Brake Fluid Do?

Brake fluid has two main jobs. The first is to transfer enough force through the brake cables to apply the brakes when you hit the pedal. It plays a key role in bringing your Volkswagen Atlas or Taos to a quick stop, ensuring you stay safe on the road in Marion.

The second task the brake fluid performs is protecting the brake components from corrosion because of moisture. One of its properties is its ability to retain moisture particles, preventing them from corroding brake cables or calipers. If the fluid gets contaminated, it won’t be able to do its job properly. So replacing the brake fluid at appropriate intervals is essential for your vehicle.

Does Brake Fluid Change Color?

Brake fluid comes in various colors, including clear, amber, bluish, red, and greenish. You can see the brake fluid color by checking the transparent reservoir in your vehicle’s engine compartment. Regularly checking it is important since you may need to top it up. Frequent checkups can also help you identify a problem with the brake fluid so you can act before it gets serious and leads to more expensive repairs.

One of the most common warning signs that something is wrong with the brake fluid is if it turns a darker color. You may notice that it appears brown or black in the reservoir. Contaminants in the fluid, such as dirt and debris from the surrounding environment, can cause this.

Another cause could be particles that have worn off components in the braking system and gotten into the brake fluid. If the fluid is black, your vehicle is probably overdue for a fluid change. Black brake fluid is seriously contaminated and may have already caused damage to other parts of the brakes.

If you want to confirm whether there’s debris in the brake fluid, stick your finger in the fluid to check its texture. If you feel any particles or grit in the fluid, it’s time to replace it. It’s well worth having a professional inspect the brake system to ensure the contaminated fluid hasn’t damaged any other components.

How Long Can Brake Fluid Last?

There are several types of brake fluid, each with a different life span. One of the most common types is DOT 3 fluid. This fluid has a relatively low boiling point and is the type you’ll need to replace most often. Typically, you’ll need to change DOT 3 fluid after 20,000 miles of driving, which takes the average driver between 18 months and two years. DOT 4 fluid has a higher boiling point and can last longer. It usually needs replacing after 60,000 miles or four to five years of driving.

Keep in mind that these life spans are only rough guides. As with other car components, various factors can impact the life span of the brake fluid, including your driving environment and habits. With a routine maintenance schedule, one of our service technicians will regularly check your vehicle’s brake system to ensure the fluid and other components are still in good condition.

What Is Involved in a Brake Fluid Change?

If you stop by for a brake fluid change, we’ll start by removing the existing fluid from the reservoir in the master cylinder. Once the reservoir is empty, we’ll add new fluid. Then, we’ll bleed the brakes at each wheel by opening the small bleeder screw. It’s crucial to add fluid to the reservoir before performing this task to get all the old fluid out of the system and prevent air from entering the brake lines. Once the brake bleeding is complete, we’ll top up the reservoir with new fluid if necessary, and you can be on your way.

Additional maintenance work may be necessary if you wait too long to replace the brake fluid. If it’s seriously contaminated, it may already have caused damage to the cables or other components. For instance, dirt or debris in the fluid may have corroded the inside of the cables.
