This not an uncommon problem. If you do a Search there will lots of discussions on the problem. The most common reasons are:
o - Chafed or broken wire inside the brake drum (the RR seems to be popular).
o - Chafed wire inside the axle housing. On a 2010 with recent brake work, this has a good chance of being it.
o - Bad connector where the brake wire connects to the main line feed.
o - Loose or rusty Bargman Plug on TV.
o - Bad connection in the Pin Box 4x4 box (this is pretty rare)
Hopefully others will have ideas on finding the problem.
