Brakes are some of the critical parts of our car, and their failure can be disastrous.
However, air can sometimes come into the brake’s circuitry. When we talk about bleeding a vehicle’s brakes, we are talking about eliminating air from the braking system.
So, how do you get the air out of brake lines without bleeding?
There are numerous techniques to remove air bubbles from your brake lines without having to bleed them completely.
You can regularly replace the brake fluid so as to to prevent air from entering the lines again. You should also install a tee, double-check all of your valves, and replace worn-out brake lines and outdated seals.
Also, ensure you clean brake lines using the brake spray lubricant.
Removing air out of brake lines is a quick and straightforward procedure, and it will take you roughly 15 minutes per wheel on average.
How to Get Air out of Brake Lines without Bleeding
Here is a simple procedure that you can do by yourself;
Step1: Jack up the Vehicle
Remove the tire and wheel by jacking up the car. Next, wipe any crud or dirt from the region where the brake lines are joined to the car with a cleaning cloth.
Make sure you clean the line properly because any dirt or oil can cause air bubbles to form. After cleaning the area and wiping away the dirt, dry it.
Ensure you use a clean towel or pressurized air.
Step2: Look for the Bleeder.
Under the braking system is the hose and screw designed for brake fluid bleeding. If you have elevated your vehicle, the easier the process will be.
Remember to protect the bleeder from stains by covering using newspaper or a piece of cloth. This is because, the brake fluid might be corrosive, so keep that in mind.
Step3: Attach Tubing by Loosening the Bleeder Bolts
Now you can release the bleeder bolt with using the necessary bolt removal tool.
After that, use a wrench to attach tubing to the bleeder valve and place it over the opening of the brake line.
At this point, ensure that the tube is long enough to allow you to position yourself away from the car comfortably.
Step4: Use Plastic Hose
You should put one side of the flexible hose in a plastic canister or glass and insert the other end inside the bleeder screw.
Fill the glass using brake fluid to the top, and then set aside your container in the region where the fluid will be dripping to if you do not have a flexible hose.
Step5: Have a Friend Apply Brakes
At this point, ask one of your friends to assist you in stepping on those brakes and advise you on the right time to do it.
Hold your brake pedal down while removing your bleeder screw after depressing it a couple of times. If you have a brake fluid container, at this point, you will see bubbles flowing from the tube.
Wait until your friend informs you that the pedal is back to the original position before closing the screw while the pedal is still depressed. Now, repeat this until there are no visible bubbles inside your brake fluid.
Step6: Clean the Bleeder Bolt
Your friend can now relax and let go of the pedals. Remove the tubing and use a cleaning cloth or spray can of compressed air to clean the bleeder bolt.
Make sure you lubricate the area where the line attaches to the your car so you do not have any trouble tightening it when you are done bleeding.
Step7: Refill the System
You can begin changing or adding new brake fluid now that you have successfully eliminated air from your brake lines.
You can now get the top cap out of the master cylinder reservoir and slowly pour in brake fluid with a funnel while maintaining pedal pressure. If bubbles are present in your braking lines, this will cause pressure to build up in the reservoir, forcing them out.
However, make sure the fluid level does not rise past the top line.
Place the parking brake on and wait for a few minutes after adding brake fluid to the master cylinder reservoir.
The amount of fluid you will need here will be determined by how much you drained out with the tube and pedal pressure, but it should be about a quart.
Pour a tiny amount of brake fluid on the location where the line connects to the automobile to check for leaks.
Then allow it to sit for a few minutes before wiping it down and checking for leaks. Now, you can tighten everything until it stops leaking, if there are any.
Step8: Tighten and Secure the Bleeders
With the help of your friend, tighten the bleeder bolts with a wrench while still watching for air bubbles in the lines.
It will ensure that no air enters the lines once more.
Finally, you can use clutch-type clamps to secure the brake line to the car.
Step9: Repeat the Process
At this point, you will repeat the procedures for the right front and back wheels and the left rear and front wheels.
You should repeat this procedure about three times for every wheel. When doing this, ensure you give your front wheels the most attention.
Step10: Inspect the Brakes
After you are finished, make sure you mop up any locations brake fluid might have leaked to avoid causing harm.
Now it is time to see if your brakes are now bled fully. So, drive your car at a low speed and repeatedly brake to check whether the feeling of walking on some sponge has gone away.
Lastly, ensure you refill brake fluid to your vehicle’s reservoir so that you will not risk having problems later.
Frequently Asked Questions (FAQ)
Is it possible for air to escape from brake lines?
If you have closed the brake system tightly, no air can escape. However, air bubbles might dissipate when you release the pressure making the brake fluid heat up.
After bleeding, why are my brakes still spongy?
Brake fluid polluted by air or moisture in the system is the most prevalent reason for spongy brakes.
How much Brake fluid will I need to replace?
To replace what you have lost due to air bubbles in the brake lines, you will need 1 to 2 gallons of brake fluid.
However, the amount of brake fluid you need to change is determined by your vehicle.
How long does it take to get the air out of brake lines?
It is a quick and straightforward procedure that will require two persons to complete. It takes roughly 15 minutes per wheel on average.
How can you tell if the brake line has air in it?
The brake pedals are spongy and soft, or the pedal falls on the floor, indicating air in the brake lines.
