How to get air out of brake lines without bleeding

Air in brake lines is caused when the brake fluid leaks, enters and accumulates in the air space between the wheel cylinders and calipers. This issue can be more common if you have old, corroded or damaged brakes that let fluid seep out of them. The build-up of air in the line prevents an even distribution of braking force, resulting in a spongy and soft pedal feel.

Fortunately there are systems put in place by mechanics and car care professionals that allow them to detect and fix any problematic air issues within hydraulic brake lines


Why Do Brake Lines Need to Be Bled?

In order to restore the functionality of your brake system, it’s important to understand why brakes need to be bled.

If you are considering upgrading to ceramic or nylon-coated brake lines, it is essential that you properly bleed the existing brake line first. This will help ensure that the pressure of the old hydraulic fluid can be released so that your new brakes can work optimally.

Brake bleeding is a process that involves reducing and eliminating any air bubbles present in the hydraulic system of a car’s braking mechanism. If left unchecked, these tiny pockets of air can lead to decreased braking performance since they impede on the brake fluid pressure needed for optimal control.

Additionally, regular bleeding of your brake line is recommended in order to keep both old and new fluid clean and free of any air bubbles, which can cause a lack of responsiveness in your brakes.

Through proper bleeding techniques, mechanics are able to flush out all traces of air from the lines, returning steady and consistent pedal responsiveness while delivering maximum stopping power.

If you want to keep your ride safe, taking the time to bleed your brakes lines is worth it!


Why bleeding brakes can be hard?


No matter how experienced you are in car maintenance, bleeding brakes may still be a challenge for some. It’s not an impossible task, but it requires patience and accuracy so as to avoid creating further complications for the brake system.

The main problem is that air bubbles can take up residence in between the calipers and wheel cylinders of your hydraulic brake lines. These pockets of air make it difficult for the hydraulic fluid to travel through the line, resulting in poor braking performance.

Additionally, mistakes made during a brake bleed can cause debris or moisture to enter into your brake lines, which could then lead to impaired braking performance and possible failure of other components within your braking system down the line.

For those who are inexperienced with brake lines, it is highly recommended to seek professional assistance for your brake bleed in order to ensure that you are correctly tackling the entire process step by step.

Things you will need when get air out of brake lines without bleeding

It’s important to have a few key items on hand if you’re trying to get air out of your brake lines without bleeding them:

How to get air out of brake lines without bleeding?

Step 1: Gather the Supplies

Gather the supplies needed to complete this process without fail; you’ll need cleaning cloths or paper towels, a few rags, a plastic tube, a wrench, and a container to catch the old brake fluid.

It doesn’t hurt to have fresh brake fluid at the ready either. Make sure everything is within arms reach and you’re all set up – let’s get started!

Step 2: Jack Up the Car:

Jacking up the car to access the tire and wheel is the major first step.

Once that’s done, use a cleaning cloth or paper towel to rid the area of debris and dirt.

This part requires your complete attention as any remaining dirt or grease may lead to air bubbles forming in the brake line – resulting in further problems down the road.

After cleaning up, make sure you dry off the area with either a clean cloth or compressed air; this will help ensure that all potential air bubbles are removed for a smooth system overall.

Jack up the car and secure it on jack stands. Make sure you’re on a flat surface before removing any wheel from the vehicle to ensure stability and safety.

Step 3: Find Bleeder Bolts:

After the car is jacked up and secure, you’re ready to locate the bleeder bolts.

Finding the bleeder bolt on your brake caliper can be a bit of a challenge. Before you start your search, it’s important to note that the bleeder bolt is, in fact, a cylindrical plug and located at one end of the brake calipers.

This seemingly insignificant part is actually critical in relieving pressure inside the brake lines. That makes finding and replacing this piece of hardware a top priority to keep your car running safely.

Step 4: Loosen Bleeder Bolts and Attach Tubing:

Loosening the bleeder bolt and attaching the plastic tubing is a crucial step in effectively bleeding your brakes.

Use a wrench to loosen the bleeder screw/bolt and make sure the tubing fits snugly on the brake line opening.

Ensure that you place the tubing far enough away from you and your car that it won’t pose any kind of accidental hazard as you work on your brakes.

The extra few minutes in these small steps will make all the difference when it comes to making sure that your brakes are properly taken care of.

Step 5: Have A Friend Apply Brakes

Have a friend apply steady pressure on the brake pedal several times and watch as old, dirty brake fluid is pushed out of the lines.

Make sure to collect it in the container you prepared before beginning; this step is critical in ensuring that all old fluid is replaced with fresh fluid.

Have your friend push down on the pedal until all of the lines are flushed and ready for new brake fluid.

Step 6: Clean the Bleeder Bolt

After your friend has completed the task of pressing down on the pedals, it is time to take off the tubing and clean the bleeder bolt.

Cleaning this important part is essential for any number of tasks, so you’ll want to make sure that you use a cleaning cloth or compressed air to make sure it’s spotless!

Make sure to also apply some lubricant around where the line connects to the car because this will help to prevent any issues when tightening it back up in the end.

Don’t worry though – with a little effort and persistence, your bleeder bolt will be as good as new in no time!

Step 7: Replace the Old Brake Fluid with the New One

Replacing the old brake fluid with new one is a must and it’s very simple to do.

Remove the cap from the master cylinder reservoir, attach a funnel and add fresh brake fluid slowly while you press the pedal.

This will cause pressure within the reservoir which will help push out any existing bubbles that may be present in your brake lines.

Make sure to keep an eye on the level as you don’t want it to go above the maximum line.

With rough calculations, you’ll need approximately one quart of new brake fluid – throw down the parking brake once adding it and let it sit for a few minutes before opening again.

One thing to keep an eye out for is any brake fluid leaks. If you notice patches of moisture near where the brake line connects to the car, it may be a sign that the line is damaged and needs replaced.

To check if your brake line is leaking, pour a small amount of new brake fluid into the area and let it sit for a few minutes; afterward, wipe it off and inspect for any markings caused by leaking fluid. If there are any leaks, tighten all passageways leading from the line until the problem is fixed.

Step 8: Tighten and Secure the Bleeders

Tightening the bleeder bolts with a wrench and securing them with clutch-type clamps is an important step to ensuring that no air gets into the brake line.

Doing this task together with someone else will make it easier, too – both of you can keep an eye out for any potential air bubbles in the lines, while one person tightens the bleeder bolts and clamps shut.

Like this, you can be sure that your brakes are good to go!

Step 9: Repeat the Process for Every Wheel

As a car owner, it is important to ensure that your brake lines and fluid are in good condition.

The only way to do this is to remove the air from each wheel and repeat the same process for every other wheel.

This can be a bit time consuming, but the safety of yourself and those you share the road with depends on it.

Not taking this extra step can be dangerous as air drawn in through old brake lines can lead to brakes failing when needed – something completely avoidable with a little effort.

Ultimately, once each wheel has been properly assesed, you will be able to drive your car with confidence.

Step 10: Fill Your Brake Fluid Reservoir

Before you hit the road, it is essential to make one last inspection of all your brake lines to guarantee that no air bubble leaks are present.

This will ensure a responsive and safe stopping power even during emergency situations. After conducting the thorough checkup, the crucial last step is to fill the brake fluid reservoir so it will be ready for future usage. 

Doing this extra step guarantees that you won’t run into any trouble mid-drive, making sure your journey runs smoothly with full security.

Step 11: Go for A Test Drive

Now that all the air is gone, it’s time to take the car for a spin!

Go out at a safe speed and use gentle stops to ensure each wheel cylinder is full of the fresh brake fluid.

When you get back, open up the cap on the master cylinder reservoir and press lightly on the pedal while using a funnel to add more fluid if needed.

Do this procedure until no bubbles are present in your brake system – then you’re guaranteed efficient stopping power with every drive!

When your brake system need to be topped off, it is important to take caution and pay attention to the line on the master cylinder reservoir- never add any past the maximum marker. Once you have added the proper amount of brake fluid, drop your parking brake and wait a few minutes.

Go for a test drive afterward to ensure everything is all set before moving ahead – check for any signs of leaks by pouring a small amount of fluid on any connections and allow some time for inspection. If needed, give each connection a slight readjustment until everything appears secure.
