if you go by the timeline, the brutes and elites were fighting together. However, the fleet that attacked reach was a bunch of elites that followed the Pillar of Autom to Halo. Although, the Arbiter did say he followed with all of the ships in his command, so that's not to say that the brutes had their own fleet that they took control of.
