I'm going to assume you're working with 18 STR at character creation and 18/19 STR at level 5 to account for the extra 4 damage at level 5
At level 7 they get Weapon Specialization
"Your rage helps you hit harder. You deal an additional 2 damage with weapons and unarmed attacks in which you have expert proficiency."
So at 7, since they gained expert in unarmed attacks at 5 with Brutality, I believe they'd have 1D12+11 damage, again assuming 18/19 STR
edit: and derp, yeah by 5 they should have striking on their handwraps so like breith says, base die (assuming they do have striking) should be 2D10 at 5 and 2D12 at 7
