In terms of matches, you got 50% of your DNA from your mother, but she has another 50% that you didn't get so she will definitely have some matches that you don't have. And your brother would have gotten a different 50% of his DNA from her, so he may have matches on mom's side of the family that you don't have. But if you come across a relatively close match who matches you and/or your brother but not your mother, then it's likely that match is on your father's side.
