    ABS fail?

    Any ideas please:
    08 JK, stock 3.8, X model, 2dr Wrang
    Front drivers brake locks immediately when pressed (and I mean right now). Its got new calipers, hoses, pads n all. No change in symptoms. Research suggests ABS component perhaps? I need a smoking gun if youve seen this please n thanks.

    The speed sensor [ABS] went out on the rear of my 2010 JK. The main symptom was a rear tire almost locking up when accelerating around a turn. The better code readers can pinpoint which wheel.

    Makes sense. Thank you for the idea.

    ABS fail?

    How does your rotor look? Thats new? I had one with a quarter sized rust ball in the face of the rotor. Daily it would lock up for the first and second stop. I ended up changing it.

    Also, how does the hard lines look? Any kinks?

    Have you bleed each wheel?

    Did it start doing this right after some brake work, or did it appear on it's own?

    Hard lines look fine (checking again tonight). Rotors are all but new. This happened ~3 months after brake work was done. I think the wheel speed sensor is next to switch out.
