There was air in the hydroboost.
I jacked up the front of the truck and turned the tires back and forth. Also got a mighty max hand pump and rigged up a hose into a used power steering pump cap. My friend pumped the hand pump keeping 20 psi while I turned the wheel back and forth from lock to lock and lightly put pressure on the brake pedal. It took about 15 minutes to get the air out. Then I took a pair of needle nose pliers and crimped the hose for 5 minutes keeping the 20 psi in the hand held pump to equalize the pressure.
Hope this makes sense!
