In 1996 I purchased new a GMC 3500 crew cab pickup truck. I noticed immediately that when applying brakes hard all power steering was lost particularly in left turns and at low speeds. Braking was not hard enough to activate the antiskid. I notified the dealer and we tried the same maneuver on three other similair trucks in his lot. All did the same thing. After many calls it was determined that this was something "I had to live with".
