Break vacum problem

[Mator]

Before I start replace parts without knowing what to start with can someone help me a break problem? I have noticed since putting everything back together that the break pedal acts like it is getting sucked in from too much vacuum. The break pedal does not come back up by itself but I can pull it up by hand. When I let go it gets sucked back in about a an inch. This causes the breaks to stay engaged until I pull it back up. I checked the one way valve at the booster and it seems okay. I pulled the vacuum hose off and plugged it and it seems to work fine as manual breaks. I do not have a lot of experience with breaks. I did have it all apart and I think I got it back where it is suppose to be. Attached are some pictures I took for reference. Thanks
