I'm glad you found the problem. I trust nobody, repeat, NOBODY with my brakes. Twice I've found the star wheel adjusters on the wrong sides so that the self adjusting mechanism loosened them instead of tightening them. I've found copper tubing in place of brake hose. I've found the rear line cut, bent over and smashed flat, then wrapped in electrical tape. I've seen calipers so neglected that the pistons were contacting the rotor- the pads had completely worn away.I've even seen the rear drums worn so thin that the entire drum separated from the hub. Scary stuff.
