what are some examples of brutus as a master of his household?

Throughout the play, Brutus alone suffers from a lack of sleep. Brutus says that, "Since Cassius first did whet me against Caesar / I have not slept" (2.1.61) He adds to this that his mind, "Like to a little kingdom, suffers then / The nature of an insurrection" (2.1.68-9). His insomnia represents an internal struggle over whether to betray his friend or act in what he believes to be the best interests of Rome. His personal struggle is a microcosm for the civil war that eventually occurs. In 4.3 Brutus again suffers from a bout of insomnia during which he encounters Caesar's ghost. Portia struggles to convince Brutus that she is worthy of his confidence. She first kneels, begging him to share his secrets, and then stands up dramatically, stating, "Think you I am no stronger than my sex, / Being so fathered and so husbanded?" (2.1.295-6), and stabs herself in the thigh to prove her strength. Brutus capitulates to Portia, acknowledging her strength. See, Brutus is a sensitive guy!
