Brake fluid is a critical component of your car’s braking system, as it transfers the force from the brake pedal to the brake pads, allowing your vehicle to stop safely and efficiently. However, over time, brake fluid can become contaminated with dirt, moisture, and other impurities, which can compromise its effectiveness and lead to brake failure. To ensure your safety on the road, it’s essential to maintain the condition of your brake fluid and replace it when necessary.
In this guide, we will provide a step-by-step process for fixing contaminated brake fluid in your car. First, you’ll need to identify the type of brake fluid required for your vehicle and gather the necessary tools and materials. Then, you’ll need to locate the brake fluid reservoir, check the fluid level, and drain the old fluid. After that, you’ll need to refill the reservoir with new brake fluid and bleed the brakes to remove any air bubbles. By following these steps, you can restore optimal brake performance and ensure your safety on the road.
Signs of Contaminated Brake Fluid
Spongy Brake Pedal
If your brake pedal feels soft or spongy when pressed, it could indicate contaminated brake fluid. Contamination can affect the fluid’s ability to transmit pressure effectively, leading to a spongy pedal feel.
Reduced Braking Power
Contaminated brake fluid can result in reduced braking power, causing your vehicle to take longer to stop. This decrease in braking performance is a clear indication of potential contamination in the brake fluid.
Burning Smell
A burning smell when you apply the brakes can be a sign of contaminated brake fluid. Contamination can lead to overheating of the brake system components, resulting in a burning odor.
Dark, Murky Color
The appearance of a dark or murky color in the brake fluid is a visible indicator of contamination. Discoloration suggests the presence of impurities or foreign substances in the brake fluid, highlighting the need for immediate attention to prevent further issues.
The Importance of Fixing Contaminated Brake Fluid
Step 1: Begin by Collecting all Required Tools and Materials for the Task.
Before you begin the process of fixing contaminated brake fluid, it is essential to gather all the necessary tools and materials. You will need a socket wrench, a brake bleeder wrench, a turkey baster or a brake fluid removal tool, a container to collect the old fluid, fresh brake fluid recommended by your vehicle’s manufacturer, and a clean cloth or rag.
Step 2: Safely Lift Your Car and Locate the Brake Fluid Reservoir
To access the brake fluid reservoir, you will need to safely lift your car using a jack and secure it with jack stands. Refer to your vehicle’s owner’s manual for the correct lifting points. Once your car is securely lifted, locate the brake fluid reservoir. It is usually located near the back of the engine compartment, close to the windshield. The reservoir is a transparent plastic container with a cap labeled “brake fluid.”
Step 3: Drain the Contaminated Brake Fluid
Before draining the contaminated brake fluid, it is crucial to clean the area around the reservoir cap thoroughly. This prevents any dirt or debris from entering the reservoir when you remove the cap. Once the area is clean, remove the cap and use a turkey baster or a brake fluid removal tool to extract as much of the old fluid as possible. Put the old fluid in a container for safe disposal.
Step 4: Flush the Brake System with Fresh Brake Fluid
Once the old fluid is drained, it is time to flush the brake system with fresh brake fluid. Start by pouring a small amount of fresh fluid into the reservoir. Then, locate the brake bleeder valves on each wheel and attach a clear plastic tube to one of the valves. Submerge the other end of the tube in a container filled with fresh brake fluid. To slow down, press the brake pedal multiple times with assistance, then keep it pressed.
While the pedal is held down, open the bleeder valve to release the old fluid and air bubbles. Repeat this process for each wheel until the fluid coming out is clean and free of contaminants.
Step 5: Bleed the Brake System
After flushing the system, it is essential to bleed the brake system to remove any remaining air pockets. Starting from the wheel farthest from the master cylinder, have your partner pump the brake pedal three to four times and hold it down. To release trapped air, turn the bleeder valve slightly while keeping the pedal pressed. Close the valve before your partner releases the brake pedal. Repeat this process for each wheel, working your way towards the wheel closest to the master cylinder. Ensure that you check the fluid level in the reservoir periodically and refill it with fresh brake fluid as needed.
Step 6: Refill the Brake Fluid Reservoir and Check for Leaks
Once the brake system is properly bled, refill the brake fluid reservoir with fresh fluid up to the recommended level indicated on the reservoir. Make sure the cap is securely tightened. Then, carefully inspect the area around the reservoir and all the brake lines for any signs of leaks. If you notice any leaks, it is crucial to address them immediately to prevent further contamination and potential brake failure.
Step 7: Test the Brakes and Ensure Proper Functioning
The final step in fixing contaminated brake fluid is to test the brakes and ensure they are functioning correctly. Start your vehicle and press the brake pedal several times to build up pressure in the system. Focus on how the pedals feel and how quickly they respond.
The pedal should feel firm and provide consistent braking power. Take your car for a test drive in a safe area and test the brakes at different speeds. If you notice any abnormalities or the issues you initially experienced persist, it is recommended to consult a professional mechanic to diagnose and address the problem.
Steps to Fix Contaminated Brake Fluid in Your Car
Identify Contamination
Check for signs of contaminated brake fluid, such as discoloration, unusual noises, reduced braking performance, or leaking fluid near the wheels.
Gather Tools and Materials
Prepare the necessary tools and materials for the brake fluid replacement process, including brake fluid, brake fluid test strips, disposable gloves, shop towels, and a drain pan.
Change Brake Fluid in the Master Cylinder
Use a turkey baster to remove old fluid from the master cylinder reservoir without fully emptying it to avoid introducing air into the system.
Flush and Replace Brake Fluid
Use brake fluid test strips to ensure the quality and condition of the new fluid.
Consult a Professional
If you are unsure about fixing the contaminated brake fluid yourself or if there are complex issues with the braking system, it is advisable to consult a professional technician for assistance.
Tips for Preventing Contaminated Brake Fluid in the Future
Use Fresh Brake Fluid
Always use fresh, high-quality brake fluid recommended by your vehicle’s manufacturer. Using old or low-quality fluid can increase the risk of contamination and reduce the effectiveness of your brakes.
Regularly Inspect Brake Fluid
Regularly inspect the brake fluid reservoir for any signs of contamination, such as a dark or murky color. If you notice any abnormalities, it is best to address the issue promptly to prevent further contamination.
Avoid Introducing Foreign Substances
During maintenance or repairs, avoid introducing any foreign substances, such as dirt or moisture, into the brake fluid reservoir. These substances can lead to contamination and compromise the performance of your brakes.
