why did braciole move it back to the bronx?
The neighborhood was turning into a cesspool. They all eventually moved up to the Bronx and Westchester.
did the colmobos ever have a presence
Not really, and they've never had a presence in the Bronx or Westchester, either. Although Greg DePalma and Richie Fusco were pretty close. Richie split his time between Brooklyn and Scarsdale, so he hung out wherever Greg was shaking some poor fuck down when he was in town.
