I can't understand that long sentence but it sounds like you're not getting brake fluid to flow from one of the wheels. If that's a rear brake look at how the vehicle is jacked up and supported. If the rear axle is hanging down the height-sensing proportioning valve will limit fluid flow to the rear wheels. It limits pressure when the truck is lightly loaded to prevent easy rear wheel lockup.
Please consider a to help us answer more questions.
