Very unusual for the lines to be bad.  Only real way to tell is to replace them.  My front break using the 38 year old lines is like a rock.  Leaver only moves half inch.  Still stops so I don't worry about it. 

Try this, make sure the caliper is level and take the top off,  while looking inside the bowl (don't stick you head over it) very slowly push the leaver (cover tank and such with rags before doing this).  Look for little bubbles coming from the holes in the bottom of the bowl.  My bet is there is air in there. If you see bubbles just keeping working the leaver in and out until there are no more bubbles.  SLOWLY both ways.  If you squeeze it to fast you will squirt break fluid everywhere. I always do this when I have rebuilt a caliper. 
Good luck

Wish there was a way to absolutely identify brake lines are bad as to what you described.  I noticed one caliper piston was pitted.  I am getting new pistons machined.
