trailer brakes

[buddie1]

here's the deal: I was traveling from West Virginia back to Nebraska pulling my 36ft 5th wheel. Stopped in Indy for the night, back on the road again in the morning no problems. Stopped in Jamesport, Mo for the night. Left the campground in the morning & my trailer started hoping brakes would come on .. off..on...off. stopped reconnected everything again same thing. unplugged the controller from fuse box so at least I would have lights no go. So unplugged from truck completely pulled home with no brakes or lights. Looking for some input. Reese controller 83500. truck 06 chevy durmax

This would be my thought, depending on age/miles on trailer. You can check by running wires across on the outside of axle.

Could your emergency brake cable be loose at the connection on the pin?

Do you know if the trailer lighting was blinking in and out as well? I had that issue on my race trailer and had to replace the 7 pin whip as not only was the brake controller going nuts the lights where flickering.

The brakes themselves are fairly simple electrically, so I'd look for a loose wire or possibly a controller problem. Try duplicating the problem in your driveway. If your trailer lights are also going on & off with the brakes, then it's almost certainly a wire problem since the controller doesn't work the lights. Also, look at the controller readout & see if the brake number changes or stays at zero.
