Install new master cylinder without bleeding?

If you really want to get into this, i do believe the average person should not be tampering with their brakes at all. Brakes should be left to professionals certified to repair them.
I am a red seal automotive technician,i have done this very thing repeatedly over 30 years. Never have i ever put any of my customers at risk due to a brake failure. Never. This particular procedure was taught to me by an even more experienced mechanic back when i was learning. Im sure if it isnt right the op wouldnt even back out of the driveway.

certified brake products had a disclaimer stating for warranty their products need to be installed by a qualified mechanic.
thank you for chiming in TJ,

Yes,what This man/member said, and I have done it many time with zero problems to this day.
