Thanks for commenting--I totally forgot to update!
So the solution was super simple. There's a bracket that was placed between the hydroboost and master cylinder. That MUST be in place (or equivalent)
for brakes to work properly. When I last replaced my master cylinder, I remember thinking "that's a strange place for that bracket to go, it probably goes on the outside (forward side) right under the nuts that hold master cylinder to hydroboost". Well, putting the bracket on the outside was wrong. It allowed the master cylinder to sit closer to/right up against the hydroboost. That little distance caused the brakes to be always "a little bit" applied, it increased pressure, which then eventually locked up brakes. So I kept the bracket on the outside, but added a washer that was the same thickness of bracket ;and placed it in between master cylinder and hydroboost. Never had a problem since. Perfect example of Occam's Razor in play: the simplest solution is usually the right one.

I have to ask ,you are saying that you have put a washer in between the housing and that solved all the problems that have caused it to lock up ??? I am having a hard time swallowing that... I took my 2004 tahoe to the dealer for a break job, they wanted 4000....I was wondering if they were going to put gold break lines or even a gold master cylinder.... I had to stop them and do for myself,... well I changed roters and break pads ,bled the system. Like we all know how to do . I am not sure what I did wrong. I started going down the street and AS it warmed up I had to increase the speed of my Tahoe because I can feel the breaks fightig up.I went to pull over and found myself skidding out of control. All the breaks were locked up. It took three hours for them to cool and release. I tried to make it home but when I pulled into my dirt driveway, well it was comical to me...I am still battling for the information on this project, I am so very tired of it all . I walk out my front door and just shake my head... WHAT IS THE SOLUTION FOR THIS PROBLEM... SOMEONE TELL ME SOMETHING ???

I deleted your email email address. Don't post your personal info publicly on the internet please. You're opening yourself up to scams and hackers. Nobody here is going to email you. Thanks.
Liljay hasn't been here in years and probably won't respond to you, so it's always a better idea to post your own thread in stead of resurrecting old ones.
What did the dealer say the problem was?
Did you inspect the conditions of the pads and calipers? Are they seized or sliding freely? Pins rusted?
Thank you
