Disk brakes are the ONLY WAY TO GO.
If it's a small trailer and you are headed to South America, I would go standard drum brakes. Simplicity and availability would win out in my mind. It's different from the USA where you can get overnight delivery of parts via amazon.
As far as the old truck tires...did you check the date stamp on them? Just because they have lots of tread doesn't mean they aren't at the end of life.
If the bolt patterns match up, that's great but if not you might consider tires that can fit either rim. Out in the hinterlands, finding someone who can swap the tires onto a different rim is actually very likely. They tend to be adaptable away from big cities.
