Steps to Follow on How to Get the Air Out of Brake Lines

Now we’ll show you the best way to get the air out of the brake lines in a way so simple that it will seem like a game when you’re doing it on your own.

Step 1. Placing a Plastic Tube

Examine and obtain the inlet to the bleeder. This should be obtained from the rear of the brakes. Attach a rubber tube about 18 inches long to the nipple of the first bleeder. When you are finished with the first one, repeat the same steps with the remaining bleeders.

Place a vacuum on the cap of a canister. Make sure there are no leaks by attaching the other end of the tube to the cap. Roll the entire product wrapper along the end of the trap. This will prevent the tube from coming off the trap.

Step 2. Save the old brake fluid

Collect all used brake fluid and recycle it. This type of old fluid can be very harmful and corrosive. As a side note, please wear goggles and dust masks for your safety.

Step 3. New brake fluid

Try using a new brake fluid, which contains a suitable formula to trap unwanted fluids.

Attach the jug and keep a safe distance from the cylinder at the rear of the wheel. Start from there and then move to other tires. Put cardboard under the jar to avoid dirt.

Step 4. Try to verify everything before you start

To start getting the air out of the brake lines, make sure everything is off. Try to check absolutely everything from the transmission to the parking brake. The cylinder reservoir should be completely full. Have a colleague step on the brake about 9-10 times and then hold it down during the bleeding process. Inform your partner of this as it is necessary to keep your foot on the brake for the process and your safety.

Step 5. Final Round.

Go to the rear wheel and carefully cut the bleeder, about a half turn maximum, until the liquid starts to come out. Wait a couple of seconds and then close it.

Also start pumping the brake pedal gently. Refill the reservoir and repeat the process two to three times. Make sure the tank is as full as possible.

There would be a concern if the master cylinder comes in contact with the piston air by mistake. Then, unfortunately, you have to start over.

Finally, make sure the master cylinder head is closed. Perform a test drive to inspect the condition of the brake line.

Step 6. Other things to consider

Check the bleed screw while in the process of removing air from the brake line. If for any reason the screw stops, it is mandatory to replace it. You will need a partner to perform this task.

At the same time, remove the screw and insert your finger into the hole. Your partner should then slowly press the brake pedal until the brake fluid reaches your finger, once this happens, fill it as soon as possible.

Continue this for a period of 10 to 15 seconds and return the screw to its original position. Repeat the process throughout your vehicle.
