My jeeps got a very similar problem to yours. Ive got ABS and i think I remember hearing somewhere that if air gets into the ABS valve controller or lines connected to it then you have to have somekind of special tool to get the air out of it. Not a vacuum bleeder but something that a dealership would have. I've bled mine several times also and it still feels a little spongy. Although I think this condition might also be caused by a weak booster or spongy brake lines. I don't really know just throwin ideas. <img src="/forums/images/graemlins/cheers.gif" alt="" />
