Well, it seems after talking to the service writer that I normally deal with (the one who actually knows what he's doing) the problem is solved. The noise I was complaining about sound that a plastic accordian style water bottle being crunched when you step hard on the brake pedal. The noise was indeed the brake booster.
The first service writer says: either learn to deal with it, or replace it for $289 + tax and the problem may still happen.
Second service writer: he adjusted the rear brake like he said he told the first service writer to do and he says the sound is gone. He says as your rear brake wear and the pedal sits at a position closer to the floor, the brake booster will begin to make this annoying sound when depressed. All he did was essentially shorten the linkage from the brake pedal to the rear brake which positions the brake pedal further off the floor board, like when the truck/brakes were new. I am still in Chicago, so this is all coming from the second service writer (whom I greatly trust). I will let you all know more when I get home on Saturday.
