Hello hydro boost was leaking in side cab. Brakes still felt fine and stopped good. Put a new hydro boost on and pedal was hard like it had very little assist. Broke open metal line at hydro and didnt seem to have much pressure. So i figured 25 year old power steering pump wasnt delivering enough. So i replaced it. Now hard pedal still very little assist and now no power steering. Yes i got air out of system. Look in the power steering pump i dont see fluid moving at all. Best i recall should be flowing in there. dual rear wheels 3500
