So the problem started when you replaced the hydroboost and not when you replaced the hoses?

Hoses are hooked up wrong or there is air in the system.
Or, you damaged something while installing the hoses.

Okay,let me do a quick summary to make sure I have this straight:
- Pump to hydroboost hose burst, you then replaced both hoses. Brake problems while driving straight ensued.
- You replaced the power steering pump 3 different times. Problems continue.
- Replaced hydroboost. Problems continue.
- Each time parts were changed, you bled the system by jacking the front end up, ran the engine to spin the pump, steered the wheels lock-to-lock repeatedly while steeping on and releasing the brakes.
- Turning brake tests were done at low speeds

Dude, you have to answer the questions we ask you in order for us to help you diagnose the issue. Not being at the truck ourselves, this is the only way for us to get information on the symptoms. We are not doing it to insult your mechanical ability. Therefore:
- What speed were straight line brake tests performed at?
- What codes are present in OBD?
- Please take a picture of the hoses as they are currently installed so we can see if there is anything else going on. In fact, the more pictures the better. Take a variety of distant and close shots from various angles.

The hose that goes from the hydro-boost to the steering gear box.... the steering gear box hose side has a small rubber o-ring that must be installed on the end of the connection (comes in a small plastic bag). Did you install the rubber o-ring before you slid the tube/hose into the steering gear box?
