Los hermanos pirata can also be possible
Los hermanos piratas
If "Pirate brothers" are real brothers sharing the family name "Pirate", then we say Los Hermanos Pirata just like Los Hnos. de la Fuente / Gonzales / Segura, etc. in singular.
But if this is the title of a story, ie: about some guys who are together working as pirates, then we say Los Hnos. piratas in plural).
We also refer to brand names this way, ie: Los coches Ford, Los zapatos Clark, Las computadoras Dell.
Occasionally, we can even talk about specific groups of people in singular, ie: Los Maya desaparecieron al principio de la conquista. Here we can also use the plural as well.
There doesn´t seem to be a gramatical reason; I too "am just following my native speaker's ear."
