The power steering lines to the hydro-boost are hot to touch? I bled the power steering and hydraulic booster, so why are they hot to touch? Thank you!

That's highly compressed hydraulic fluid. If it doesn't get hot, something's not working. Put your hands on the head of an air compressor and feel how hot it gets from compressing cold air to just 120 psi. It will burn your hand. Power steering fluid gets compressed to 1100 psi and will get real hot too.
