The Brutes are completely harmless outside the Banshee, as all they do is walk around. But, like all Brutes, they will go berserk if you kill their partner. On the ground, it will have no weapon. Walk up to him and walk backwards. While walking backwards the Brute will follow and will be doing somewhat of a "Gangster" style walk. It is recommended that you destroy the Wraiths and draw attention from the Banshees by firing at them with a weapon such as a Plasma Pistol. Some players often call them "pet" brutes.
