Yep, the springs keep the brakes from self applying and also pull the shoes away from the drums when you lift your foot. So a loose spring could allow the shoe to wedge out against the drum and lock up the wheel.

Wow, make sense now!!!!! Thank you for explaning it to me in idiot terms I just know we will be ok on our first trip to FL in our TT because there will be people like you all there to help........
Sounds like technician error. Either it was loose and came off when the tech was inspecting/adjusting brakes or he knocked it loose. Either way, sounds like the tech did not double check his work when done. Should be fine now.
Good luck and have a great trip!
