I have seen old trucks with a drum (sort of) brake on the driveshaft...
it was called a band brake, and was sort of a reverse drum, one long
flexible pad that wrapped around the outside and was tightened by a
cable.
whenever used (in motion) the cab of the truck would fill with horrible
(prob toxic) brake smoke........
needless to say, it is not found on modern trucks
