disc brakes for trailer, not vehicle...
Drum brakes on trailers are electric and very easy to use, and almost everyone (who tows serious) has the electric brake controller, so the trailer will be useful down the road.
Unless trailer is super heavy then do not go disc. Drum brakes are fine as far as being able to do the job. Often the tires of the trailer lock up way way before the drum brakes are pushed to any sort of limits. This means the drum brakes are working very well, and almost all light to medium weight trailers will be operated by a brake controller turned way way down (low power setting). So, seems most do not need more power from brakes.
