Brakes are one of the most essential components of our vehicle, and they mustn’t fail.
However, sometimes air can get into the circuit, so we are going to offer you a step-by-step tutorial that will explain how to get the air out of brake lines without bleeding.
When we talk about bleeding the brakes of a vehicle, we are referring to the act of removing air from the braking system.
Hydraulic brake systems in modern cars use a fluid that flows through a pump.
Sometimes, the braking system weakens due to too much air entering the system, so we need to know how to bleed the brakes of a car to remove the air.
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: Find the bleeder
A screw and hose are located under the brake system and will be used to bleed the brake fluid. It will be easier to access if the vehicle is elevated; a jack or towers can be used.
Don’t forget to cover it with a cloth or a thick layer of newspaper to prevent it from staining. Be aware that brake fluid can be caustic.
Step 2: Use the plastic hose
Insert one end of a flexible hose into a glass or plastic canister and the other end into a bleeder screw.
Fill the canister to the brim with brake fluid. If you do not have a flexible hose, place the container in the area where the product will fall.
Step 3: Using the braking system
This is the time to ask someone to help you step on the brake and to tell you when to step on and off the brake.
After depressing the brake pedal several times, hold it down while you remove the bleeder screw. You can see bubbles coming out of the tube if you have a container of brake fluid.
Close the screw while the pedal is still depressed and wait for your partner to certify that the pedal has returned to its original position: up.
Repeat this process until no bubbles are visible in the brake fluid.
Step 4: Refilling the system
When you have finished bleeding at the first station, you will need to refill the entire braking system with brake fluid.
To do this, remove the top cap from the master cylinder and replace it with a new container.
Do this carefully, as you don’t want the brake fluid to trap air bubbles and force you to start over.
Step 5: Repeat the procedure.
Repeat these steps for the left rear, left front, and right front and rear wheels.
The procedure should be repeated three times for each wheel, especially the front wheels.
Step 6: Check the brakes.
When you’re done, be sure to clean up any areas where brake fluid has spilled so you don’t damage them.
Now it’s time to check if the brakes have been completely bled: take your vehicle for a spin at a very low speed, braking repeatedly to see if the sensation of stepping on a sponge has disappeared.
How To Get Air Out Of Brake System [Solved]
Will air work its way out of brake lines?
No air can escape if the braking system is tightly closed. Even air bubbles will dissolve as soon as pressure is released and the brake fluid heats up.
How long does it take to get the air out of the brake lines?
This is a simple process and is not difficult to do, however, you will need two people to do it. It will usually take about 15 minutes per wheel.
Why are my brakes still spongy after bleeding?
The most common cause of spongy brakes after bleeding is brake fluid contaminated by air or moisture in the system.
Can Low brake fluid cause spongy brakes?
A low brake fluid level can cause a soft or spongy feeling in the brakes as you step on the brake pedal.
How do you tell if there is air in the brake line?
Symptoms that indicate air in the brake lines are:
Spongy brake pedal
Soft brake pedal
The brake pedal falls to the floor
Final Thoughts – How to Get the Air Out of Brake Lines
Bleeding the brakes is a do-it-yourself task that every driver should learn. It is a simple procedure that anyone can perform. When doing this job, be sure to follow all safety rules as much as possible.
