Can a vacuum pump cause a NPR brake issue?

What should I do about my Isuzu NPR brake issues?
If not I recommend u loosen the lines at the master cylinder and let brake fluid gravity bleed out of them, don’t remove all the threads, just enough to wear brake fluid starts seeping out. After that go ahead and bleed the brakes starting at the passenger rear, driver rear, passenger front and finally drivers front.
Why does the NPR pedal go to floor first time?
Re: 05 isuzu npr brake pedal goes to floor first time and… I’ve found on vehicles with drum rear brakes, if the rear brakes aren’t adjusted correctly, the pedal must be pumped up to get good pedal. The reason is you have to make up the distance from the shoe to the drum before the pedal builds pressure in the system.
