I have heard that the calipers do stick and need replacing, but I dont think that is the root cause of machine gunning. If the trailer we were talking about had drum brakes, I would say they need adjusting. I dont think the old drum brake were self adjusting, so in other words you had to adjust them. The procedure was adjust until the shoes make contact and then back off 5 clicks. If you did not back off and then used the trailer, I bet you would get very grabby brakes or machine gunning. I have never tried, just a guess.
