We changed the hydro booster and power steering pump and the pedal goes all the way to the floor. We can’t bleed them. we don’t understand why the pedal stays on the floor.

Good evening,

With the length of the truck and the air trapped, I would go to a parts store and get a pressure bleeder, not a vacuum bleeder. That will force all the air out of the system.

Pushing down the pedal does not move the air enough to the bleeders.
