When I need to drive brass screws into hardwood, I not only drill a pilot hole but I will often also find a comparable  steel screw and drive that in first.  That expands the hole further and also pre-cuts the treads into the hole so that the brass screw is less likely to break off.  A little wax or soap on the screw adds a little extra insurance.
