Sometimes ramps are enough to allow you to get to what you need to, but space can be a challenge bleeding brakes at home without the car in the air.Site Navigation. It can even be a challenge to manually bleed the rest of the brake system at home for the same reason. This is because it can be a tight squeeze to get a wrench to it. You can buy one and like has been mentioned the top of the line OBD2 scanners can also normally do what is required, but it is costly.Īlso, it is hard to do at home because in order to get to the bleeding valves on the ABS module you will normally need the car in the air. That is because the special tool that is required is expensive. So, this leads to the question of can you bleed the ABS module at home? Well, the answer is yes you technically can, but it is hard. That is because most of the air out of the ABS module is going to go into them. Then the new brake fluid can go in which in turn forces more air out.Īfter using a tool to cycle the valves, you will then need to bleed the brake lines again manually.

The tool cycles the different valves while the brakes are under pressure to help allow air to come out. Some OBD2 scanners can do the same thing.

If the air is trapped farther in the system though you will need a special tool to get the air out, different vehicles require different dealer tools that plug into the OBD2 port. This should allow the air out and cause the lights to go off. After you loosen it to keep the brake depressed and tighten it back. This will cause lights to come on the dash which is what is supposed to happen. After the brake pedal is depressed to loosen the brake sensor. It is important the system is under pressure before doing this to help force the air out. Then you need to depress the brake pedal. The first thing to do to bleed the ABS module is to start the car or turn the key to where the battery is on. Depending on where the air is trapped though will determine how hard it is to bleed the ABS module. Most ABS modules do have bleeding valves, but a lot of times these aren’t enough to get all the air out. Bleeding ABS Moduleīleeding the ABS module is more of a challenge than just bleeding the brake system because the ABS module has a lot of chambers and moving parts in it. If bleeding the brake system like this though doesn’t fix the problem of mushy brakes though or you know the ABS module has air in it, then you will have to bleed it. You will have to look up the information depending on the make, model, and year of your car. This is due to how the system is set up, and there is the most efficient way to bleed the system. You repeat this process until fresh, clean fluid comes from the system.ĭepending on the vehicle you will want to start with a certain brake line either the front or the back. This will suck new fluid in and cause some old fluid to come out once old fluid stops coming out close the bleeder and have the person lift their foot off the brake. After they depress the brake you loosen the bleeding valve a quarter turn. Then you have your helper depress the brake pedal with enough force to stop at a light. You put the hose that you are bleeding into some fresh brake fluid. To get the rest of the old fluid in the air out though you will need a partner to make it easier. Once the master cylinder is empty, you can add in new fluid. You also want to suck out all the old fluid from the master cylinder. You want to make sure you have clean fluid ready first though before bleeding the lines however you want to open all the bleeder valves and let them drain. The way you bleed air out of the brake system is by opening the bleeder valves at the proper time. For bleeding the air out of the brake system itself, it also helps to have a partner.
BLEED PRIUS BRAKES WITHOUT TECHSTREAM FREE
It is best to make sure that the rest of the system is free of air first before trying to bleed the ABS module because bleeding the ABS module can be a challenge for someone to do on their own.

This is because you might think you have air in the module, but it is really in another part of the system.

BLEED PRIUS BRAKES WITHOUT TECHSTREAM HOW TO
How to bleed brakes?īefore going into how to bleed the ABS module, we will first briefly explain how to bleed the brakes. Well, bleeding the ABS module can be a bit more of a challenge, but this article will explain how to do it. Most of the time bleeding brakes isn’t too hard, but what if air gets in the ABS Module. This can be dangerous because it means that it will take longer to stop. The reason the brake pedal will be soft and mushy is that the air will have to be pushed out of the way before the fluid can do what it is supposed to do. The reason you have to bleed the brakes is that air is compressible and if there is air in the system, then the brake pedal will feel soft. This means removing all the air in the system. Whenever you change a part of the brake system, you will need to bleed the brake system afterward.
