I have a 1970 ltd that I am trying to get back to storage without trailering it because as we all know, who wouldn't rather drive! The problem is I replaced all of the rear brake lines and the brakes were bled and great, but now I stand on the pedal and hardly get any slowing down. I was thinking that perhaps the vacuum works with the power brakes and maybe I have a leak there? The vacuum still works partially because the headlights still go up and down (but they do not stay down), any ideas would be appreciated.
