no power steering and no brakes. both fluid levels are fine. is there something

I think Your truck is equip with hydro boost, possible the hydro boost unit is going out.

see answer #1 about the steering and brakes.now,did the shift indicator cable break,or did the thumb wheel bracket break under the dash?does it look like you are in R,but really in Park,or maybe indicator may be off a couple spaces?if so,that's an easy fix and cost about 5 cents to fix it!
