Post brake question

OK, Vehicle, one ton 4 wheel drum.
The pedal stays on the floor when you depress it. I think I know what it is, but I'm looking for ideas/input.
You can reach down and pull it back up by hand, but it'll stay down there all day if you let it.
They do stop the truck.
Any one?

thats odd,

the master cylinder itself has return springs inside the casting itself, and then the pedal has its own return spring,

hmm wierd,,

Yeah fast, I'm thinkin master cylinder too.
The brakes work fine whn you hit them, just won't return the pedal.

power brakes...it does seem kinda hard to depress the pedal, but it is holding it's vacume though. I can unplug the line after shutting it off and get the his.

Mine did the same thing......seemed to hold vacumn,& felt like it worked,but wouldnt release! You might try a shot of lube on all the points(could be the peddle itself is sticky on the pivot)....69 longhorn.
