Lose Power Steering problems of the 2005 Chevrolet Suburban

I was driving on the expressway when I had to apply a strong force to the brakes in order to avoid hitting a vehicle. Simultaneously, the surburban brakes became very stiff and I lost power steering at the same time. After applying an extreme excessive amount of force I was able to stop the vehicle and avoid an accident. I had to find the nearest exit and while doing so it was extremely hard to make a 15 degree turn and also extremely hard to come to a complete stop. It was very dangerous and I was scared for my life. I told a mechanic about this and he said it sound like a bad hydro booster. I looked it up online and saw that there was a recall on it. When I looked it up it said 0 open. This is definitely a safety issue. Please help!.
