Is your fluid full? Any leaks at the Master cylinder or any of the wheels? Have you checked the flex lines going to the front wheels to see if they are split?

I'm thinking it could be a master cylinder or any of the above. The system should hold even if the truck is off.

If its not leaking I would lean towards the master cylinder, pop a line at one of your tires and have some one pump the brakes no fluid pressure then it's your master cylinder.

My avatar is my goal for the 7.3

I pulled left rear wheels off and there was brake fluid all over the inside of my inner wheel I'm leaning towards caliper cuz rotor is wavy and destroyed and i did feel it dragging for a couple days and didn't think anything of it at first now guess the pistons in caliper ain't working. Does this sound like a possibility
