I have the same problem. I run through the brake oil nice and slow so no bubbles are left, then after an hour or so of running bubbles start to appear again. :confused:
 
Seals might of gone around the bleed nipples/screws, you can use ptf tape, the tape plumbers use around joints and threads and that should sort it.
 
I just checked my hydros that I got on my car, when I opened the master cylinder the thing is only half way full, no air bubbles.. The brakes work fine, but is this normal...
