How to Bleed Brakes

Mechanic checking brake fluid

Brake bleeding is just one of the many brake services that help keep the entire braking system in excellent condition. If there’s air trapped in your vehicle’s brake system, you probably want to know how to bleed brakes to release it. While learning how to bleed brakes by yourself isn’t too complicated of a process, it can be time consuming. You can always feel free to schedule a service appointment at Sunshine Chevrolet, Llc to have our expert technicians take care of your car brake repair. But, if you’re someone in Asheville who enjoys the hands-on experience of maintaining your vehicle, we’ve created this helpful guide on how to bleed brake lines just for you!

Why is it Important to Bleed Brakes?

While bleeding the brakes may sound like a daunting task, it’s a critical part of car brake service. As you drive your vehicle throughout Hendersonville, the moisture resistance of your brake fluid deteriorates and will begin to absorb water. Air is another element that can get into the brake system which gives your brake pedal a “soft” or “spongy” feeling when pressing it. As a result, bleeding the brakes helps to get rid of trapped air, making your brakes feel much more firm.

Steps on How to Bleed Brakes by Yourself

If you’d like to bleed your brakes at home in Fletcher, you’ll need a few materials: brake fluid, a box-end wrench, a fluid holder and tubing, and an assistant to help you. Once you have these ready, you’ll need to follow the steps below:

Step 1:

Consult your owner’s manual to ensure that you have the correct brake fluid. Since there are many types of brake fluid, it’s important to know which is the proper fluid for your vehicle. The owner’s manual will also provide you with the brake fluid replacement intervals.

Step 2:

Once you’re on solid and level ground, jack up your vehicle and remove all of the wheels.

Step 3:

Locate the four caliper bleeding screws and loosen them. (If they don’t loosen immediately, don’t twist hard with the wrench. Instead, spray the screw with penetrating oil and wait about 30 minutes. Then try again. If the screw strips or snaps, do not proceed — bring your car to our service center right away.)

Step 4:

After you loosen all of the screws, tighten them again. Keep in mind that bleeding your brakes is a slow process since you’ll have to bleed one brake at a time. The other three screws need to be tight to avoid air bubbles.

Step 5:

Pop the hood and check the brake fluid level in the master cylinder reservoir to make sure that your vehicle has the right amount of fluid. While you’re bleeding the brakes, keep the master cylinder cap unscrewed but still resting on top of the reservoir. To begin, you’ll need to bleed the brake furthest from the master cylinder, but your vehicle may require a different order. You can always check your owner’s manual or ask a technician for guidance.

Step 6:

Secure the end of a piece of clear tubing (about 1/4 inches in diameter) over the first bleeder screw. Place the other end of tubing into a receptacle, such as a plastic bottle. You can also buy a brake bleeding kit from any auto store — or order one online — that’ll have these items. In any case, the tubing needs to be long enough that you can place the catch container above the bleeder screw’s height. This way, any air caught in the tube won’t revert back into the brake caliper.

Step 7:

This is the step where you’ll need the assistance of another person. Make sure the car engine is turned off, and ask your assistant to press the brake pedal several times until they feel resistance pushing back against the pedal. Instruct them to keep pressure on the pedal. In the meantime, open the bleeder screw a bit. Fluid will travel through the tube and the pedal will start dropping closer to the floor. Be sure to remind your assistant to keep applying pressure.

Step 8:

Have your assistant let you know immediately before the pedal touches the floor. Once they notify you, close the bleeder screw right away. Then, check the master fluid resevoir’s fluid level. You may need to add new fluid.

Step 9:

Repeat the previous two steps about five times at the same bleeder screw, or until the stream of fluid no longer has any bubbler.

Step 10:

Then, repeat steps 7, 8, and 9 on the other three bleeder screws in the correct order — starting with the screw further away from the master cylinder and moving to the one closest to it.

Step 11:

Once you’ve finished bleeding your brakes, ask your assistant to apply the brakes then quickly release the pedal. While they’re doing that, keep an eye on the fluid in the master cylinder reservoir. If you notice a lot of bubbling, this indicates that there’s a lot of air in the system and there’s still work to be done. However, if the fluid is moving only slightly, you’ve bled the brakes fully.

Step 12:

Before you put the wheels back on your car, tighten each of the bleeder screws and apply just enough pressure to make sure they’re secure.
