What does it mean when I push the brake pedal, the car stops, but the pedal does not go back to its original up position, and I have to kinda bring it back up with my foot. If I do not do anything the pedal goes back up very very slowly.
Opinions anyone? Thanks.

sticking calipers or bad bushings in the pedal assembly.

Sticky calipers or plugged hoses won't make the pedal stay down. Bad bushings will, and they're bad as a result of a master cylinder leak, which may be past or current. Rebuild the pedal cluster and replace the offending master cylinder. The Cap'n

wholeheartedly. You have bad pedal bushings.

Thanks to all which begs the next question ?

Is it better to do the whole pedal assembly or just the bushings - isn't the same time to do both - remove, do and reinstall ???/ BTW it is a alsmost concours 76 2.0 white/tan Thanks again.

One "is" the other unless you can find a new pedal assembly. If you're willing to pay for a new assembly, go that route.

What I mean is; as stated, if you're going to remove the assembly, do it all (proper prep, paint/powdercoat) before you install new bushings and put it back.

The hardest part can be getting the clutch arm off. Some can get stuck and stuck good.

What Eric did not mention is that he can also supply beautifully refinished pedal assemblies. There are a few others that can rebuild them also.
There was a good deal on master cylinders on eBay recently. Chinese made I believe, but might be good value.
Generally, you need to replace the MC, the rubber lines, and rebuild the pedal assembly about once every 10 to 12 years. That is also pretty true for caliper rebuilds also. Not too bad if you maintain them on a regular basis.

At the risk of getting political... The stories of Chinese lousy QA are legion. I would not trust anything as important as my brakes to a Chinese bargain.
