Brake Problem?

I put a vacuum pump setup for my brakes.

The issue I'm having is that sometimes, when I hit the brakes to slow down when I first hit the brake pedal, it is hard, like the booster isn't working.

Then, it will soften up as the pedal should feel.

I know it's not a vacuum leak.

I've let it sit for a while, then unhooked the hose, and you can hear the air release.

I've tried to get it to act up with the engine off so I can listen and hear what's happening, but it works fine.

Has anyone else had the issue?

Does anyone have any ideas on what to try?
