Hard to brake and no power steering ????

I got in my car yesterday and started to drive to the store. When I was going down the road I noticed my power steering was whining . Then it started to get tuff to turn and my brakes were barley working and smoke coming from my hood on the left side. when I got to a store i popped the hood I saw power steering fluid pouring from around the acuumulator on the Hydro-Boost unit leaking down on to my exhaust manifold causing the smoke. its leaking out as fast as i put power steering fluid in and crank the car it all goes out. do i need a new hydro-boost unit or is their a
seal or something in the acuumulator that can be replaced with out buying a new one cause money is real tight please help?????? ps i got a 97 mustang gt
