Bench bleeding is a way  of filling the cylinders with fluid, and not air.
If there's no air in the cylinders, less air gets in the system, and there's
less air to bleed out.

The basic idea is that you hook hoses to outlets of the cylinders, fill the
reservoir, and work the pump.  Many master cylinders (not Girling ones, of
course) come with the needed bits.  You can also make one out of brake bits,
if you've got them around, or buy a kit (dorman, the Help! people, sell one
that fits most stuff for about ten bucks) from your FLAPS.

yes, it will.  But bench bleeding the slave will prevent the problem.
