The Brake Fix Is In
They need to check with GM TAC to make sure they have installed the correct programming. Stage kit + pump equal different program than pump only.
Had the brake fix installed yesterday. Took them six hours. The work order shows the following:

Started the car this morning and still took about 2 mins. to build up 20lbs. vacumn.
Checked with the service manager and they did get the correct program. He indicated that he had another that was also not providing good brake pedal and it did not have the stage kit, so they were going to do some more investigation. Will update when I know more.




Rear brakes grinding gone.
