Brick Break removes Light Screen and Reflect from the opponent's side of the field (even if it targets an ally), then inflicts damage. It wont remove Light Screen and Reflect even if the target is immune to Brick Break (i.e. a Ghost-type Pokémon). It will not remove Light Screen or Reflect if Brick Break misses or the target is protected from Brick Break.
