Bottom line is, either you go at it with a small triangular file and be
really careful and probably mess up a few bits before you get good at it
(that's been my history with such things, anyway), or you get a new bit.
There might be professional sharpeners out there. Haven't found one yet.

If they are really cheap bits, the file is a good way to go.

If they are good bits, though, you won't have much luck - they are probably
high speed steel which the file won't touch.

You should be able to find a sharpening shop that can handle the brad points,
but unless they are large expensive sizes it may be cheaper to buy new ones.
