Help with brakes.

O.K. guys, I've read each response and I understand what you all are saying. I really appreciate each of you taking time from your day to help someone you don't even know. I have already ordered the correct parts for my dart. Not sure if the PO bench bled the mc or not. I would be inclined to say no at this point! I will get all of the new stuff installed and go through the entire procedure again. The mc that the po put on is most def foe a disc/drum set up, but the rears are plumbed to the larger side than the fronts. I know that in itself isn't the problem but, I also know it's wrong. I will get it back right! he did have the fronts adjusted so tight that the front wheels slid on the gravel and the grass. It looks like at least he did the new brake set up right. Thanks again to all who responded.
