    It's not. If you've bled brakes before, you'll be fine. And the stainless lines make a nice difference in pedal feel.

    I suspect air in the ABS because I have no clue what I’m doing lol. The pedal feel changed since doing the line change, the pedal travels a couple inches before the brakes engage which it didn’t do before. I bled a whole half liter of fluid with no bubbles coming out for a while, so if there’s air in there I don’t know where it is.

    I’m looking forward to it once I can get everything sorted. Right now the pedal feel has become worse since changing the lines. Once the pedal hits resistance it holds firm and returns to top when released so I’m pretty sure it’s air and not a bad master cylinder

    The question that should be asked is, how low did the fluid get in the reservoir?
    Did it ever go dry? If so, air could be in the ABS Module.

    The reservoir never went dry, I kept it filled the whole time. I don’t even know where the ABS module is. Is it the metal box with the hardliners coming from it near the air injector in the 2.5gen in the engine bay?

    If that’s all you’re doing, just bleed as usual. Don’t worry about the ABS.

    Edit: don’t shake up the brake fluid bottle. Let the bubbles rise and out. Also gently fill the tank.

    Agree with rnish above - changed all lines and simple bleed with key not on works. Sucked old fluid out of reservoir and put new in before bleeding system at each wheel.
    No air in reservoir/ABS pump to start. Brakes are not highly sensitive on Tacoma anyway depends on rotor/pad type used. Lines may help but doubt you will feel much difference.

    Sooo I was struggling with a 'brake' problem.

    We bled the system, ran the techstream ABS purge. I thought I had got air in the system at the resivour, while wheeling with some steep angles.

    It seemed to fix it at 1st, then it would just return and go away at random. All in the same test drive.

    :bananadead:

    Ends up my front passenger wheel bearing is the cause of the weird feeling in the brakes. As you apply the brakes, you are moving the wheel and tire around. The felling is multiplied in the peddle because there are 2 pistons. o_O



    Now I know what that feels like. :cookiemonster:

    Mine were pretty touchy before and now they are a little more mushy, so I have to go back to the drawing board and bleed some more

    On my 07’ the abs module is on the passenger’s side fender well. I am not sure where it is on the 2.5. But yes, it will have hard lines going to and out of it.

    It’s obvious the brakes are not the same.
    You can continue to bleed them as you have been. But I’m not sure the purpose?
    Why continue to do what does not work, and expect different result?

    There’s been a few people that couldn’t resolve spunggy brakes without activing the abs module.

    Maybe @Bishop84 has some tips for guys with out a scan tool?

    That’s why I love tw, half the forums say bleed the ABS with a scan tool the other forums say there’s no need. I’m gonna bite the bullet and get a scan tool just to have. And I’ll use it for the ABS and see if there’s a difference after

    I guess you could try and bleed the Master Cylinder?
    See - Here
    Other than that, I really do think the next option is a scan tool.
    Or, find a dirt/gravel road, and get the ABS to come on.
