As a car owner, it’s essential to stay on top of your vehicle’s maintenance to ensure your safety on the road. One critical aspect of car maintenance is brake fluid, which plays a vital role in the braking system. When you notice that your brake fluid has turned black, it’s a sign that something is amiss. In this comprehensive guide, we’ll delve into the world of brake fluid, exploring what causes it to turn black, the risks associated with it, and what you can do to address the issue.
Brake fluid is a hydraulic fluid used in the braking system to transmit pressure from the brake pedal to the brake pads, which then slow or stop the vehicle. It’s a critical component of the braking system, and its condition can significantly impact the performance and safety of your vehicle. When brake fluid becomes contaminated or degraded, it can lead to a range of problems, including reduced braking power, spongy brake pedals, and even brake failure.
So, what causes brake fluid to turn black? In this article, we’ll explore the common causes of black brake fluid, the risks associated with it, and the steps you can take to address the issue. We’ll also cover the importance of regular brake fluid checks, the different types of brake fluid, and how to choose the right one for your vehicle.

What Causes Brake Fluid to Turn Black?
Brake fluid can turn black due to various reasons, including contamination, degradation, and moisture absorption. Here are some common causes of black brake fluid:
Contamination
Contamination is one of the most common causes of black brake fluid. When brake fluid comes into contact with air, moisture, or other contaminants, it can become dirty and discolored. This can happen when the brake system is not properly sealed, or when the brake fluid reservoir is not properly maintained.
Types of Contamination
There are several types of contamination that can cause brake fluid to turn black, including:
- Moisture: Water and humidity can seep into the brake system and contaminate the brake fluid.
- Dirt and debris: Small particles of dirt and debris can enter the brake system and contaminate the brake fluid.
- Oil and grease: Oil and grease can leak into the brake system and contaminate the brake fluid.
- Brake pad material: Brake pad material can contaminate the brake fluid, especially if the brake pads are worn or damaged.
Degradation
Brake fluid can also degrade over time, causing it to turn black. This can happen due to exposure to heat, light, or oxygen. When brake fluid degrades, it can lose its effectiveness and cause problems with the braking system.
Factors that Contribute to Degradation
Several factors can contribute to brake fluid degradation, including:
- Heat: High temperatures can cause brake fluid to degrade.
- Light: Exposure to sunlight can cause brake fluid to degrade.
- Oxygen: Brake fluid can degrade when exposed to oxygen.
- Age: Brake fluid can degrade over time, even if it’s stored properly.
Moisture Absorption
Moisture absorption is another common cause of black brake fluid. When brake fluid absorbs moisture, it can become contaminated and discolored. This can happen when the brake system is not properly sealed or when the brake fluid reservoir is not properly maintained.
Consequences of Moisture Absorption
Moisture absorption can have serious consequences for the braking system, including:
- Reduced braking power: Moisture absorption can cause the brake fluid to become less effective.
- Spongy brake pedals: Moisture absorption can cause the brake pedal to become spongy and unresponsive.
- Brake failure: In severe cases, moisture absorption can cause the brake system to fail.

How to Address Black Brake Fluid
Addressing black brake fluid requires a thorough inspection and maintenance of the braking system. Here are some steps you can take to address the issue:
Inspect the Brake System
The first step in addressing black brake fluid is to inspect the brake system. This includes checking the brake fluid level, brake fluid color, and brake pad condition.
Brake Fluid Level Check
Check the brake fluid level to ensure it’s at the recommended level. If the level is low, top it off with the recommended type of brake fluid.
Brake Fluid Color Check
Check the brake fluid color to ensure it’s clear or light brown. If the fluid is black or discolored, it may be contaminated and should be replaced.
Brake Pad Condition Check
Check the brake pad condition to ensure they’re not worn or damaged. If the brake pads are worn or damaged, they should be replaced.
Replace the Brake Fluid
Once you’ve inspected the brake system, it’s time to replace the brake fluid. This includes draining the old brake fluid and refilling the system with new brake fluid.
