That's why I mentioned bench bleeding it before installation. Bench bleeding should always be done, but some guys will bench bleed the MC w/it on the car. In your case, this wouldn't be advisable, IMO. Instead, just carefully secure it in a padded vise or something along those lines (Workmate, perhaps?).
Bench bleeding will get the air out of the master, how to keep it out when you install it is going to be rather messy...
