I got a old hydro boost and rebuilt it and put it in the truck and now my brakes aren't working like they should. There is not anymore bubbles coming from the power steering reservoir so I believe I got all the air out. I did also drain the power steering pump and replace the lines going from the power steering pump to the hydro boost. It steers fine but when I press the brakes they feel firm but just don't want to stop. When the truck is off and you have pressure on the brakes when you start it up the pedal will go to the floor, but once you let the pedal come up the brakes firms up. I also bled the brakes, I'm thinking maybe my hydro boost is bad since it isn't the one that was on my truck.
