Morphology

stepbrother = step + brother (transparent) = step + brother

Clear, productive kinship compound: 'step' (relation by marriage) + 'brother' yields the expected meaning.

Etymology

Stepbrother is made of step and brother, where step was used for someone who 'steps into' a family through marriage, as in stepmother or stepfather. So, a stepbrother is a brother 'by marriage' and not a brother 'by blood'.
