power steering and brake failed on 1997 GMC Safari

We turned a sharp corner and lost power steering and brakes. we are ver confused and need to know why. We have done some research and came up with the pump or maybe the hydraulic systen or the solenoid. Please help us narrow it down to something.

power steering pump runs the steering and brakes assist. you may have low fluid, pump fialure or hydro booster fialure. take it to a shop and let them tell you. each part is expensive and guessing could be even more expensive.
