Last night we had to haul to a 4-h horse clinic. And it was the first time we hauled the trailer since december, we checked the trailer to make sure everythign was working fine and everything was in working order also. The trailer brakes all work and everything, but everytime you would put the break on in the truck and slowed down the electric breaks made a squeeling noise, so why is my electric breaks making a squeeling noise when i stop?

There's a degree of squealing to be accepted.
Most trailer brakes have an electromagnet that when on, is attracted to the rotating side of the drum. As the magnet is pulled by the moving drum, it moves a lever that pushes the brake pads against the brake drum face, slowing the rotation. (and the trailer!)
So .. now you understand how it works... how much squealing is going on??
Excessive squeal could be caused by rust on the drum, loose parts, worn pads, glazed pads, or lack of adjustment among other causes.

My first guess would be rust build up. Probably taking the wheels of and using some sand paper to knock of the rust on the drums and spray clean with some brake cleaner would help.

Brakes that have been idle for a while may make some noise, but use will eradicate a little rust. (Not if the assembly is rusted solid, but then you would have had NO brakes)
The most common brake part failure is that the adjuster spring breaks, and it and/or the adjuster is loose inside the brake assembly. It can cause major damage to the shoes, or it can just roll around in there and not hurt things too much. It is capable of all kinds of noise.
