Do I have to take the vacume pump off to check the the shaft or is there a way to get the power steering pump off without doing this?

I have tried to bleed the system 3 times and still have nothing. If I look inside the power steering pump should I see the fluid moving around? I looked and cant see it moving.

I lost my power steering and brakes. I left it set for a couple days started it up and let it run for about a half hour and got them back, but had a loud noise coming from the pump when I turned our hit the brakes. I had read in a couple places to change the fluid, started to do this and noticed the fluid was all foamy. I changed the fluid and it took for ever to get power steering and brakes. Drove it this morning and lost it again, went to check fluid and seen it was coming out the fill cap, opened it up and it was all foamy again. What do I need to do?
