Lou, I am pretty sure the brakes work in reverse. That little cam at the top would push the other shoe towards the drum, and the magnet would push the left shoe towards the drum.

As Len and Cheri stated, you can disable the brakes for a short time on the Prodigy (at least the Prodigy 2).

Like I said I am no trailer mechanic and was going on the graphic for my guidance. If the magnet was dragged forward and the lever has room to move in that direction, I guess the top cam could press on the top of the rear brake shoe enough to apply it.

No way to disengage that in the Chevy IBC that I am aware of.

Ok I unplugged the 7 way and it will back up freely no resistances what so ever. I only have this problem on my 5er not on any other trailer. I guess it could be in the trailer wiring??

Sounds like some detective work is in order.
Easiest way is to connect trailer, put truck in reverse with parking
brake applied firmly. Engine off, key on!!
Test the brake wire with a meter.
If you've got voltage you've got a problem in the wiring.

I agree with a previous poster, sounds like your backup lights are crossed
with your brake wire.

Good luck!

Sort of what I was thinking, I will have to wait as it is raining like crazy here and will be for a couple days. I will check it out later on this week, thanks for all the responses.

Quick question, what brand of brake controller are you using?

It is made by Draw Tite I think it is Accurate 2 or something like that, it is digital.

If that is the Activator II, then that is a time delay brake controller. No wonder there are problems backing.

Someone, including myself, should have asked the obvious question that Road-King asked.

Lonewolf, is this the unit ?? Draw-Tite Activator Electronic Brake Control 1-2 Axle Trailers (2-4 Brake Trailers)

If so, you should easily be able to adjust the output control to 0 while backing, then put it back to your regular settings when leaving the campsite.

Better yet, consider a proportional controller.

I had that same BC, I'am fairly sure it will send volts to the brakes in reverse. I just changed to the PC2.

Like was mentioned earlier maybe there is some short with the back-up lights and break lights in the TT wiring. The other idea KyDan has for checking volts with the truck in reverse is a good idea too. Because you don't have the problem with other trailers and no brakes with the 7 pin plug unhooked, I would think that rules out your truck, brake controller and driving with your foot on the brake.

That just leaves your 7 pin plug and the wiring on your TT to each brake.
