Decide if you wish to get the air out of your brake lines through the master cylinder, bleeder screw, or hydraulic lines. The efficiency, efficacy, and accuracy level are not the same for all of these steps, so you'll have to decide which one works for you.

Let's start with how to get the air out from the bleeder screw.

3. Locate and unscrew the bleeder screw and attach the hose.

The bleeder screw is located at the top of the brake caliper. It's designed as a long, cylindrical piece with a rubber cap on it.

You can use a wrench to unscrew the bleeder screw one at a time. You should wear hand gloves to protect your hands from the corrosiveness of the brake fluid.

If the bleeder screw is stuck or won't lose due to rust or corrosion, then you use a wide brush to clean it a bit with penetrating oils or give the screw a gentle tap with a small hammer. Ensure that the taps are gentle to avoid cracking or destroying the caliper and screws.

After loosening the bleeder screw, attach one end of the tube to the bleeder screw and another end to an empty plastic container. The tube should be long enough to reach a container on the ground. You'll need the container to catch the breaker fluids as they come out.

4. Pump the brakes with a friend’s help.

After firmly securing one end of the hose on the bleeder screw and the other end into the container, get a friend to pump the brakes while you watch the hose.

Make sure the tube is fully submerged in brake fluid, and there are no leakages to prevent air from entering the brake lines. For extra protection, you can wrap the bleeder screw with a cloth material to ensure that it doesn't pull out from the bleeder.

5. Close off the bleeder screws and remove the hose.

You can have your friend continue applying the brakes until all the fluids are completely drained. However, you can choose to stop applying pressure when you don't see any more air bubbles coming out of the tube. Close off the bleeder screw and remove the hose.

Ensure that you clean the bleeder screws to prevent dirt from getting into the system. A little lubrication on the metal parts will prevent tightening problems.

6. Refill with new brake fluid.

Now that you've drained all the air from the brake lines, together with the brake fluid, you can proceed to refill the brake fluid reservoir with new brake fluid.

You can do this by adding brake fluid from the master cylinder reservoir.

How To Get Air Out of Brake Lines Without Bleeding From the Master Cylinder

Using a hose on the bleeder screw isn't the only way to get the air out of the brake lines. You can also get out air from the master cylinder reservoir.

All you have to do is to open your car's hood, locate the master cylinder reservoir and open the cap. Clean the cap and put it back, but this time around, you'll place the arrow in a position that points toward the wheel that you need to pump first. Repeat this process for all four wheels of your car.

In this position, get a friend to continuously march on the brake pedals at least 20 times until it becomes firm and you can't feel air coming from them again.

Some cars have dual-master cylinders, so you must ensure that you repeat the process for all the cylinders. Refill with new brake fluid when you are done.

You can start your car's engine and step on the brake pedal another 20 times to remove any excess air that wasn't flushed.
