Thanks Rock.

The dealer is getting approval from Lippert to swap out everything but the axels.
I didn't even have to raise a fuss.

U think maybe Lippert had a problem during there Assy. Look what happened to my brakes Even though it had to happen during shipping why would one melt. All it takes is bad seals to cost the brakes. Hopefully my dealer who is installing everything ensures all is well. When jaco installes axles they come fully Assy from Lippert.

If this brake swap turns out to be my problem...I'll go out on a limb and say maybe your problem was your rig had brakes like mine and the delivery guy was using his manual slider in the mountains of Tennessee and Kentucky on his way to Florida.
That's how I drive mine when going down way smaller hills that I have around my parts and when I am coming to a faster stop.
And I can smell them burning.

No, I don't think the brakes will lock. Mine will roll slightly on pavement, but drag through grass and sand. I know cause I had one set of wheels on pavement and one set on grass. I could move the rig if I had too, but would not do more than drag it to the side of the road.

Thanks namusmc.
What happens when your on the road with your controller maxed out?

I did some more testing on my brakes.
Pulled the pin.. I can pull the trailer forwards or backwards at 1200rpm. It feels firm but it's fairly easy to pull. It's about the same amount of force, pulling the pin, as squeezing the manual slider.

According to Lippert each mags should be at 3.2 ohms. Math says in parallel that would equal .8 ohms.
Lipperts specs then are... total resistance (.8 ohms) at 12.5v (my controller's max output) equals 15.6amps.
eTrailer's brake system check says brakes should be pulling 15-16.3 amps.
Sounds like good braking to me.

But.....

I checked my magnet's total resistance with a multimeter. I didn't detach any of the wires, I just checked them hooked up in parallel from the first magnet. 1.2 ohms.

My trailer's magnets total resistance is 1.2ohms, so at 12.5v that equals 10.4a.
(12.5v is what my truck controller puts out with the trailer hooked up)
The current number (10.4a) is figured only with math. Not a meter reading.
That sounds like weak braking.

Next I just used the trailer with the trailer's battery. With real meter readings.
10.4a on the meter with 11.5v, on the meter, when the brakes are powered.
With math that equals 1.1ohms in total resistance. Very close to my previously measured 1.2 ohms.
Taking into account I'm not using Fluke meters, and my cheap meter's accuracy isn't that great, my conclusion is the total resistance is too high.
Either bad connections at the splices or a bad magnet or all bad magnets, or a combination of all three.
I don't have enough current going to the magnets to get powerful braking.

Hopefully Lippert will authorize my dealer for a full brake swap.

Might be bad wiring but I also read where the different axle capacity brakes have bigger magnets. You can actually install larger axle capacity brake magnets on different axles. So in the future I will install 8k axle brake magnets on mine when the time comes for replacement. Since u r getting new brakes u need to ensure the drum is flat on the surface that the magnets ride on. Probably only a brake machine shop can do that most dealers are clueless and eye ball or straight edge. Since u r getting new brakes u might want to consider having the drums turned and the inside magnet area turned flat. That way u will have new backing plates and known good drums. Even some new drums are not trued and can cause poor breaking

I'm hoping for a FULL swap. Drums included.
If they have a different plan we will have to have a little chit chat.
I'm not leaving a stone unturned this time.
As I heard the service manager say to Lippert, this is strike three.
I'm telling them to check the wires in the axels too for any unusual resistance too.

Brakes are done and the dealer did a highway check and said they work great. I am hoping to get it back this week but now another issue. During my PDI in Nov I found the slide bracket not properly installed. Well the moron who put in the repair order said 1.5 hr repair request to Jayco. Well after nine weeks at the dealer they decide to fix the bracket which was last on there list. Well guess what, the only way to replace it is to remove the complete slide. I do not want that to happen. So today they r getting with Jayco to see if installing a doubler repair over the bracket (I suggested that) will be authorized by Jayco. I do not see how those four little metal L shape brackets can hold the Schwintec frame to the FW wall. I am hoping those brackets were just used to position the frame in place and that then it is bolted to the wall frame.
