Default Brake Master Help... is it bad?

Hello, been having some brake issues... they work but pedal seems longer than should be. Replaced master recently along with front calipers. I think the new master could be bad.

Below link is vid of noise coming from master.
- noise when car off pumping pedal.
- bench bleeding in car, NO noise and no air bubbles.
- master disconnected NO noise from booster.

No visible leaks, except very slightly wet between master and booster, but could be shiny sealant or from past spillage.

What do you think? Unless suggest diff, I will either replace with orig or another new one.

If it is leaking between the master and booster then I would say the master is bad ??? Clean everything and recheck !!!

If it is leaking it's not obvious and I never see a decrease in fluid. I'm interested what people think of the noise... I don't have any experience whether it's normal or not.

Sounds like an air leak from booster.

No its the master... with low pressure when bleeding in car there's no noise. The more I think about this it has to be a bad master. Since its new I second guessed myself.
