That is a problem. Check your brake lines for leaks, brake fluid reservoir(s), brake valves for clogs preventing flow, etc.

You need to start at the master cylinder and work your way back to find where the loss of pressure is occurring. That truck has a two chamber master and if the cylinder is putting out pressure then trace it back to where you do not have pressure!

I would suspect the load sensing valve,mounted on the rear axle.It is probably seized up or disconnected.

DO NOT DRIVE THE VEHICLE!!!!!!!!!!!!!!!!!!! Have it towed to a shop and repaired.

The nature of your post leads me to believe that you are not able to do the repair yourself.

DO NOT DRIVE THE VEHICLE!!!!!!!!!!!!!!!!!!! Do not try to repair it yourself.

Remember that you have no way to know the quality of the answers you get here, including this one. The three responses, so far, have not lead you to any solutions. (no offense to the responders) They suggest more work for you. But that's fair, you didn't ask a question.

Towed? If it hasn't got brakes it needs to ride on a trailer that has!

On some vehicles there will be no pressure at the rear brakes ...if jacked up on the chassis.

Put trestles under rear axle to carry the load before bleeding brakes
