Brake fluid is a critical component of a vehicle’s braking system, responsible for transmitting pressure from the brake pedal to the brake pads or discs. However, brake fluid can become contaminated over time, leading to a range of problems including reduced braking performance, brake failure, and even damage to the brake system. In this comprehensive guide, we will explore the importance of brake fluid, the causes of contamination, and the steps to fix contaminated brake fluid.
The importance of brake fluid cannot be overstated. It plays a vital role in ensuring the safe operation of a vehicle, particularly in emergency situations. Brake fluid is a hydraulic fluid that transmits pressure from the brake pedal to the brake calipers or wheel cylinders, which then apply pressure to the brake pads or discs to slow or stop the vehicle. The fluid is designed to withstand high pressures and temperatures, but it can become contaminated over time, compromising its performance and safety.
Contaminated brake fluid can lead to a range of problems, including reduced braking performance, brake failure, and even damage to the brake system. When brake fluid becomes contaminated, it can lose its ability to transmit pressure effectively, leading to a spongy brake pedal or a decrease in braking performance. In severe cases, contaminated brake fluid can cause brake failure, which can result in a serious accident.
So, how does brake fluid become contaminated? There are several ways, including:
Water contamination: Water can enter the brake system through various means, including condensation, rain, or flooding. When water mixes with the brake fluid, it can cause corrosion and damage to the brake system.
Dirt and debris: Dirt, dust, and other debris can enter the brake system through various means, including wear and tear on the brake pads or discs. When these contaminants mix with the brake fluid, they can cause corrosion and damage to the brake system.
Contaminated brake pads or discs: Brake pads or discs that are contaminated with dirt, dust, or other debris can transfer these contaminants to the brake fluid, causing contamination.
Incorrect brake fluid: Using the wrong type of brake fluid can cause contamination. Brake fluid is designed to be used in specific applications, and using the wrong type can cause corrosion and damage to the brake system.
Identifying Contaminated Brake Fluid
Identifying contaminated brake fluid can be a challenge, but there are several signs and symptoms to look out for. These include: (See Also: How Much Are Brake Replacements? The Ultimate Cost Guide)
Spongy brake pedal: A spongy brake pedal is a common sign of contaminated brake fluid. When the brake pedal feels spongy or soft, it can indicate that the brake fluid is contaminated.
Reduced braking performance: Reduced braking performance is another sign of contaminated brake fluid. When the brakes are applied, the vehicle may not slow or stop as quickly as it should.
Brake failure: Brake failure is a serious sign of contaminated brake fluid. When the brakes fail, the vehicle may not be able to stop, which can result in a serious accident.
Corrosion and damage: Corrosion and damage to the brake system are also signs of contaminated brake fluid. When the brake fluid becomes contaminated, it can cause corrosion and damage to the brake system, which can lead to further problems.
To identify contaminated brake fluid, it is essential to check the brake fluid regularly. The brake fluid should be checked for color, consistency, and smell. If the brake fluid appears dirty, cloudy, or has a strange smell, it may be contaminated.
Removing Contaminated Brake Fluid
Removing contaminated brake fluid is a critical step in fixing the problem. The process involves draining the contaminated brake fluid and replacing it with new brake fluid. Here’s a step-by-step guide on how to remove contaminated brake fluid:
Draining the Contaminated Brake Fluid
Draining the contaminated brake fluid involves locating the brake fluid reservoir and draining the fluid into a suitable container. The brake fluid reservoir is usually located under the hood of the vehicle, and it may be labeled as the “brake fluid reservoir” or “master cylinder reservoir.” To drain the brake fluid, follow these steps: (See Also: Do You Have to Resurface Rotors When Replacing Brake Pads?

Locate the brake fluid reservoir and remove the cap.
Use a turkey baster or a brake fluid pump to draw out the contaminated brake fluid.
Drain the brake fluid into a suitable container, such as a plastic container or a drip pan.
Repeat the process until all the contaminated brake fluid has been drained.
Replacing the Brake Fluid
Replacing the brake fluid involves installing new brake fluid into the brake system. The new brake fluid should be compatible with the brake system, and it should be installed in the correct amount. To replace the brake fluid, follow these steps:
Install a new brake fluid filter to prevent contaminants from entering the brake system.
Install the new brake fluid into the brake fluid reservoir, following the manufacturer’s instructions.
Check the brake fluid level to ensure it is at the recommended level.
Test the brakes to ensure they are functioning properly.
Cleaning the Brake System
Cleaning the brake system involves removing any contaminants that may have entered the brake system. This may involve cleaning the brake pads, discs, or other components of the brake system. To clean the brake system, follow these steps:
Remove any brake pads or discs that may be contaminated.
Clean the brake pads or discs with a suitable cleaning solution.
Inspect the brake system for any other contaminants or damage.
Replace any damaged or contaminated components.
Preventing Contaminated Brake Fluid
Preventing contaminated brake fluid is easier than fixing it. Here are some tips to help prevent contaminated brake fluid:
Regularly check the brake fluid: Regularly checking the brake fluid can help identify any contaminants or problems before they become serious.
Use the correct brake fluid: Using the correct brake fluid can help prevent contamination and ensure the brake system functions properly.
Clean the brake system regularly: Cleaning the brake system regularly can help remove any contaminants or debris that may have entered the brake system.
Replace brake pads and discs regularly: Replacing brake pads and discs regularly can help prevent wear and tear on the brake system and reduce the risk of contamination.
Recap
Fixing contaminated brake fluid requires a thorough understanding of the brake system and the steps involved in removing and replacing the brake fluid. The process involves draining the contaminated brake fluid, replacing it with new brake fluid, and cleaning the brake system. By following these steps and taking preventative measures, you can help ensure the brake system functions properly and safely. (See Also: How Much Cost to Replace Brake Pads and Rotors?
