hydro boost issues

[1979jimmy350]

I am having some issues with the hydro boost in my truck. The pedal is very slow to return after being depressed. When i turn the truck off the pedal will stay down for hours keeping my brake lights on. What could be causing this?

is the spring still connected to your brake pedal assembly?

I have this issue too, due to no spring. Anybody know where to get a spring or have a picture of one?
