Brake pedal is not returning

[banana70]

Hello fellas, After installing the reman master cyl and power booster, the pedal is not returning to the upper position, the brakes were bleed and the car stops fine but I have to return the pedal by using my foot other wise the car would stay stopped/parked with the brakes applied.

Here's  what I think might be happening is:
1) Pivot screw to tight
2) bad spring on the master cyl
3) Bad/Wrong power booster
4) Missing part???
5) Vaccum???

Any Ideas??

Thanks as usual for all your comments and support

Damn, me too. My 72 Charger brake petal won't return.  It is very hard to pry it back up too. then without touching it, is is sucked backed down.

1 - possibly
2 - no spring in there
3 - possibly
4 - some thing could be missing
5 - vacuum should have no effect

PROBLEM SOLVED... # 1 was the winner.. bolt was too tight also rear pass side line was little loose at the cyl. with some air entering to the rear system...  she's ready (only a/c hoses and system charge pending).

post with pictures coming soon!

Also, a spring in where ?
My problem is not fixed, but I am glad yours is

sounds liek a bad booster if the pedal is being sucked down

 Yes, I think so.  After reviewing your Number selection of possible issues, I realized you were referring to his number of Possible issues. Sorry for being absent minded. Thanks. I will try them all.
BUT, you said vacuum will have no effect on number #5 possible issues.? doesn't the booster add vacuum ?

Vacuum would have no effect on the pedal not going to the top in his case , in your case the pedal is being pulled down by vacuum different situation

 Okay thanks.
