Ask him anything, it doesn't matter. A knight or a knave AFAIK is always male.

knight and knave are merely a title given to the person (at least in this case it is
)

OK, assuming this isn't any of your trick questions then the traveller should ask something like "If I asked you if your sister was a knave, would you say 'yes'?"
If the brother was a knave he would lie to a first lie which will force him to tell the correct answer. If he was a knight then he will give the same correct answer straight away.

Let me explain my answer:
Assuming the sister is a Knave.
My question "If I asked you if your sister is a Knave, would you say 'Yes'?" is actually composed of 2 questions:
1. Is your sister a Knave?
2. Will you say yes to the first question?
so the Knave will answer:
1. No (because he is a liar)
2. Yes - final answer
and a Knight will answer:
1. Yes (because he will the truth)
2. Yes - final answer
got it?

yeah but its simpler than that
Just ask the brother if he and his sis are the same type
If the answer is yes, she's a knight
If he is a knight and sis is a knight, ans - yes
If he is knave and sis knave , ans - No
If he is knave and sis knight , ans - Yes
If he is knight ans sis knave, ans - No
Simple.....

or just ask "do you have a sister?" if he says yes, he is a knight, if he says no he is a knave.
And then ask is ur sister a knave, and voila u have the correct answer!!
