Air in brake lines..

So again it seems to be the problem is with the front brakes. I had my wife do the old pump pump hold...(the breaks funny guys).. I started on the passenger side and sure enough lots of air and foamy brake fluid for came out clear..
Driver side some bubbles for nothing play passenger side. What should the brakes were hard again... also I'm kind of suspicious of that line catching a lot of heat being as it is routed right behind the hot engine...
