help me out here guys...I am telling you we felt nothing at all when this pin pulled. What questions should I be asking the mechanic or GD? The mechanic said the brakes were white on the inside from excessive heat...and there were charred wires that ran alongside the melted hydraulic line.

If the wires are running parallel to the hydraulic lines and they overheated due to excessive current, that would explain the damage to the lines. I'm making an assumption that the brakes were overheated from friction. If that is the case, I'm at a loss as to why you wouldn't have felt them activate. I'm hoping some of the mechanical types on here will weigh in.

Thanks Jim. I think I stated this before...but our TV is a 2017 Silverado 1 ton diesel...and our trailer is a 2017 Solitude 310GK.

There is a big difference between a full brake apply at crawling speeding and at highway speed. Most who have experimented with this have found that there is a road speed above which they cannot lock the electric drum trailer brakes. The heavier the trailer, the lower this speed will be because of the inertia of the moving trailer.
Drum brakes overheat and lose friction between the shoes and the drum very quickly. So, if you didn't feel the initial apply because of road speed and inertia of the trailer, you would not feel the continually lessening braking ability as the shoes and drums heat. At some point the wires to the electro-magnets would probably melt and short out. Because there is no fuse in the emergency brake apply circuit this would cause the brake apply wires to overheat.
The above is just my theory . . . but fits with what the OP describes and what I have heard from others and observed in their damaged parts. Melting the hydraulic lines is something that I have not heard of before.

So I am confused. Are we dealing with drum or hydraulic discs?
