Following the article, you will get a step by step guideline about the answer to the above question. If you are facing the brake problem, take a sigh of relief and check out this article.

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

Below you will find out the steps written in a very easy way to solve that problem on your own.

Step 1: Attach a Plastic Tube

Check the bleeder and gain access to it. You can do this from the back of the brakes. Take a plastic tube of around 18 inches and attach it to the nipple of the first bleeder. If you are done with the first one, repeat the same process for the other bleeders.

Take a jar and insert a hole into the cap. Attach the other end of the tube onto the lid and make sure there are no leakages. Use any food packaging and wrap it around the bleeder end. This will make sure that the tube doesn’t detach from the bleeder.

Step 2: Recycle Old Brake Fluid

In this step, wear an eye goggle and a dust mask to be on the safer side. Take all the old brake fluid and recycle them. Recycling is very much important as these old fluids are very corrosive and harmful.

Step 3: Use New Brake Fluid

Use a new brake fluid with the appropriate formula to catch any unwanted fluids. You can invite a friend to help you out throughout this task.

Link the tube and the jar at a distant wheel from the master cylinder that is in the right rear (RR) of the tire. Start from RR and then move to the other tires. Take the cardboard and put it under the jar.

Step 4: Check Everything

Before you start getting the air out of the brake lines, turn off the ignition. Check everything from the handbrake to the transmission (in park mode). The reservoir of the master cylinder should also be full. Tell your friend to pump the brake pedal for around 10 times and then hold it downwards.

Inform him that during the time you open a bleeder, the brake pedal should go to the floor. Not only that, he should hold the pedal constantly towards the floor.

Step 5: The Final Part

Move to the RR wheel and gently crack the bleeder until the fluid starts to come out. Open it about a maximum of half turn. Give it a couple of seconds (around 4 to 5 seconds) and then close it.

Pump the brakes gently and repeat it. Fill up the reservoir again. Repeat the process two times, and always make sure the reservoir is full to its extent.
Likewise, do the same thing for the other wheels. Maintain the sequence of wheels starting from right rear (RR), left rear (LF), rear front (RF), and left front (LF). For the front wheels, you might have to go for three repeats, but it depends on the condition of your vehicle’s wheel.

If you accidentally let the master cylinder come in contact with the air in the piston, you will have a problem. Then, you have to start it over again, unfortunately.

Finally, check the cap of the master cylinder and make sure it is locked tightly. Go for a test drive to check the brake line condition.

Other Plausible Reasons

You can check the bleeder screw while getting the air out of the brake line. If the screw gets stopped, it needs repairing. Thus, you will need at least two people to get this job done.

At the same time, remove the screw completely and put your finger carefully into the hole. Tell your friend to slowly pump the brakes until the fluid starts coming out and touches your finger. Fill up the reservoir before this process.
