Welcome to DF
I will move your post to the 2nd Gen Ram section.

 

Rear brake line above the gas tank.

 

Total brake failure? Make sure you have plenty of fluid. It's possible that you have air or some type of obstruction in the system. Check that out, maybe bleed them and see what happens. Check all of your brake lines, make sure they're not broken.

And, last, but not least, maybe your master cylinder has failed?
