I own a 97 Scamp
16'. I bought it in Oct of 2013. When I checked the brakes
I found that the shoes were bare metal but no damage to the hubs. I have the Dexter 3,500 lb axle
. I thought about replacing the shoes but when I checked on ebay I found that I could buy complete Chinese brake units with backing plates for about $65 a pair. I see they are now $82.77 with free shipping. I bought them and it was I think a 4 bolt installation and a couple of elect. splices. One person's easy is another's nightmare but I found it an easy job. I have hauled the trailer over 12,000 miles since then with no problems with the brakes
Good luck on whatever you choose to do.
