Location: Yahara River Chain | Here's what you need to do to convert.
1) Take off the old hitch (if it is bolted on - that will be easy, not so if it is welded on) and put a hitch in with an actuator. This is a hitch that has a hydralic ram that compresses when you stop.
2) Run brake lines to the trailer wheels. Most run down one side to a union (a "T" that splits the line to each wheel). Also you will need a rubber line from the frame to the caliper or drum that flexes when you hit road bumps.
3) A solenoid to stop the flow of brake fluid to the brakes when backing up. Some come with a "lock out" at the hitch and if you want to get out every time you back up, you can skip the solenoid. I will guarantee that if you have disc brakes you will not be able to push your trailer up any kind of incline without being locked out.
4) Convert your trailer wire harness from a 4-flat to a 5-flat. The extra wire is tapped into your reverse lights that cancels your trailer brakes when you you back up. This extra wire activates the solenoid.
5) Buy hubs with disc/drum (if you are doing this, get disc brakes - much better at stopping and self adjusting by adding more fluid). You should be able to get a kit that includes a bracket to hold the caliper, the caliper, & disc.
I think it would be much easier to by a trailer with brakes, unless you are very mechanical. If you were, you wouldn't be asking this question.
If you have to hire someone to do the convert, you are better off just buying a trailer with brakes. Parts & Labor will add up quickly and surely will cost you more than a new trailer would (or close to it - I would guess).
