Steps To Get 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. Place a plastic tube

Check the bleeder and access it. You can do this from the back of the brakes. Take the plastic tube about 18 inches long and place it on the nipple of the first bleed. If you did the first thing, repeat the same process for the other bleeders.

I take a bottle and insert one of the holes in the lid. Place the other one in the other end of the lid tube, try to make sure there is no leakage. You can use any container, wrap it around the bleeder, this will ensure that the tube does not come off.

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. Use 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.

Do the same with other wheels. If you accidentally let the master cylinder come into contact with the air in the piston, you will have a problem and will have to start over, unfortunately.

Finally, check the master cylinder cover and make sure it is well sealed. Always perform test drives to check 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.
