Truck Forums - 96 ram front brake problem

I am working on my buddys 96 Ram. While he was driving the front end started to shake. When he got home he smelled the brakes burning so he figured the calipers were binding up. So, he decided to just put on 2 new calipers. We changed the left one first. When I removed the brake line from the caliper - no brake fluid ran out of the line - like it usually does when you remove the line. I put the new caliper on and blead all the air out of the caliper and line - like usual. The brand new caliper (once blead) would not release pressure against the pads. The new caliper binds up.....We moved on to the other (right) side and it is a totaly different story...The caliper replacement went perfect. The fluid flowed out freely when I removed the brake line, and I even gravity blead the caliper with no issues at all....We then went over to the left side and blead the lines once more (until we were sure there was new fluid in the left front line). It did not work - the brake caliper presure will not release all the way - thus binding up the left front...The right front works perfect..Does anyone have an idea as to what may be the issue here? Can it be the brake line? The line is not kinked in any noticable way. It does have anti-lock brakes...
