New power steering pump ...Now very weak brakes?!?!?

I just replaced my power steering pump and all of the lines. I refilled the system with fresh fluid. I took it for a spin to bleed the air out of the system. I turned the wheel from end to end multiple times to make sure I got out any air. I re-checked the fluid level afterwords. After all of this I still have very weak brakes. From 20MPH it takes me a good 40-50 feet to stop. And when I hit the brakes it makes a louder than normal whine. Not sure what the problem is or what the solution is....Does anyone have any clue what the problem is?? I sure would appreciate your help...Thanks!

I have a 2002 F-350 7.3L Diesel

Yes, I used ATF. Amsoil synthetic to be exact. I just took it for another spin too... Power steering works great...breaks are still very bad. One thing I discovered was that when I apply the brakes while turning, the brakes engage and are strong like they are supposed to be. So the problem is between the power steering pump and the hydroboost???

Look up "power steering flush on 7.3" on you tube. Good how to video for this.
