upon removal of the master cylinder, their is a rod that connects the cylinder to the booster.
Do you know if this rod is adjustable? That is, can the rod be lengthened or shortened to adjust brake pedal throw to specifications?
I have not done a master cylinder on an Infiniti/Nissan, but others I have bled the master cylinder "on the bench" for the first bleed procedure (before installing on car).
They have kits similar to attached, some come with a new master cylinder.
This procedure is applicable to conventional Master Cylinders in general; check instructions with the new MC to be sure it applies to your car!
I am sure this procedure is on you tube.
Below is a link to a MC bleeder kit.

I do final bleeding last.
