Changing brake fluid is a critical maintenance task that should be performed regularly on all vehicles. Brake fluid helps keep your brakes functioning properly by providing a consistent brake feel, and it also helps protect your brake system from corrosion. In this step-by-step guide, we will walk you through the process of changing brake fluid on your car. We’ll provide tips on how to make the process easier, and we’ll also recommend some tools and supplies that you will need. Let’s get started!
What is Brake Fluid?
Brake fluid is a hydraulic fluid that helps transfer force from the brake pedal to the brake pads. When you press the brake pedal, the force is transmitted through the brake fluid to the calipers, which then apply pressure to the brake pads. This action stops the wheels from turning, and it’s what allows you to control your car while driving.
Brake fluid is typically made from a mixture of glycol and water. The glycol helps to prevent the brake fluid from freezing, while the water keeps the brake fluid from boiling. It’s important to use the correct type of brake fluid for your car; otherwise, you could damage your brake system.
Signs You Need to Change Brake Fluid
There are a few signs that you may need to change your brake fluid, including:
- Brake pedal feels spongy or soft
- Fluid is leaking from the brake system
- Brake pedal is slow to return to its original position
- Fluid level is low in the reservoir
- Brake pedal feels hard to press
- Changes in brake performance
If you notice any of these signs, it’s important to have your brake system inspected by a qualified mechanic. They will be able to determine if you need to change your brake fluid.
How Often Should You Change Brake Fluid?
Most manufacturers recommend changing your brake fluid every two years or 24,000 miles, whichever comes first. However, if you drive in stop-and-go traffic or in other conditions that are hard on your brakes, you may need to change your fluid more often.
A Step-by-Step Guide on How to Change Brake Fluid
- Prepare your work area. You’ll need a clean, flat surface to work on, and you’ll also need to gather all of the tools and supplies you’ll need before you begin. This includes a new container of brake fluid, rags, gloves, a funnel, and a socket wrench set.
- Locate the brake fluid reservoir. This is typically located under the hood of the car, and it may have a cover that needs to be removed.
- Remove the old brake fluid. Using a funnel, carefully pour the old fluid into a container for disposal. Be sure to dispose of brake fluid properly; it can be harmful to the environment if it’s not disposed of properly.
- Clean the reservoir. Once the old fluid has been removed, use a clean rag to wipe out the inside of the reservoir. This will help remove any dirt or debris that could contaminate the new fluid.
- Add new brake fluid. Using a funnel, add the new brake fluid to the reservoir until it’s full. Be sure to use the correct type of fluid for your car.
- Replace the reservoir cap. Once the new fluid has been added, replace the reservoir cap and ensure that it’s tight.
- Bleed the brakes. This step is critical in ensuring that your brakes are working properly. To bleed the brakes, you’ll need to have someone help you. Have your helper pump the brake pedal while you open the bleeder valves. Once the fluid starts to flow out, close the valves and have your helper continue pumping the pedal until the pedal feels firm. Repeat this process until all of the air has been bled from the system.
- Test your brakes. Once you’ve bled the brakes, it’s important to test them to ensure that they’re working properly. Drive around the block a few times, making sure to stop and start frequently. If your brakes feel good, then you’re all done!
