Narrative:

Aircraft X landed 22L and exited the runway. Aircraft X advised LC1 they have hot brakes. Cab coordinator and controller in charge made calls to roll the trucks. Aircraft Y was on the ILS 22R. Ground control 1 advised there were trucks on 22R that were not in communication with ATC. Everyone made a blanket transmission to attempt to get a hold of the trucks. After several failed attempts aircraft Y was told to go around.not one of the trucks (maybe 5-6 of them) showed up on the asde-X. No primaries; nothing. If the visibility was low this most definitely would have resulted in an accident. The asde-X has been acting up for several months now; with an upcoming major construction project this needs to be fixed. Driver training to include local ATC. I don't know who teaches these driver classes but it might be a good idea to include ATC on it in some way.
