the break-away pin just pushs back in. it's just a wedge to keep two contacts apart.

I set my integrated Ford brake controller on the highest setting and still could not lock up my electric brakes on my new A Frame trailer. The dealer service manager asked me to pull the emergency brake switch on the tongue (as a test) which DID lock up the trailer wheels. He said that many newer integrated brake controllers will not allow locking up of the trailer brakes, as they are designed to work that way in conjunction with the truck's braking system.

That's weird to me, Are you sure they are adjusted correctly? Pulling the Emergency brake is putting pure 12 volt to the magnet. That shows it working but I would check the adjustment of them. What if you had to lock them up to stop and not cause an accident?

One would have to know if the integrated controller was even capable of putting 12v-13.8v to the brakes. The ABS is a funny system, it is supposed to prevent locking brakes.

An ABS needs wheel sensors (magnetic pulse) to determine if the wheel is turning or not. How might a brake controller get that feedback from a TT that doesn't have those sensors. Seems like there might be feedback system between the truck's computer and it's integrated brake controller that tells the controller the truck isn't moving. This feed back may bias the controller output based on TV speed. Whatta ya think?

Jacking up the RV and applying the foot brakes does not fully activate the brakes. The prodigy works on momentum and the harder you stop the TV the harder the RV works to stop. Or just use the manual lever on the brake controller if you do jack it up.

I hung the break away cable a couple of times and locked up the breaks when I was beginning. Couldn't figure out what was wrong for a while. Installed the pin back in with no damage.

The break away pins would only fit one way on my previous rigs.

I am thinking you are correct about some type of feedback. My 2013 DA shows voltage output to the trailer when stepping on the brake. I have it set at 7.5 and usually will slide it over manually when I start moving in the morning as a way of warming the brakes up. I learned quickly not to mover it too far as it will put my head into the steering wheel. If I push the lever all the way over and not moving that trailer will not move when I step on the pedal but the front end of my truck will rise slightly tell me she's ready to hit the road.

Weird to me too. I would have someone else check things.
