OK so I had that correct the track bar and drag link need to be parallel and if you look in the attached pic, they are very close. I am going to look at the disco's next and see if one of them could be hanging up on something during a dive of the suspension. I guess it could be a intermittent caliper problem but they are fairly new and don't act up at all when not in hard braking. Well no pic for now, did not know I had to host it. Will do later.
Thanks,
