The Brazilian association also demanded FIFA launch an investigation into the "violent challenge" by Colombia's Juan Zuniga which saw star striker Neymar ruled out of the tournament.
If Brazil's appeal of Silva's suspension fails, they will line up against Germany missing two key players after Neymar's injury exit.
