HHR SS Brake Problem Continues

HHR SS Brake Problem Continues
I had the brake TSB done on my 2008 Auto HHR SS a few weeks ago. It made the brakes worse during cold start up! No doubt about it.
I took the car back to the dealer yesterday and they can't seem to find the problem. They told me "That's just something the automatics are going to do. You'll need to let it warm up."
WHAT?!?!?
Help! Any ideas? Suggestions?
Thanks!

I never really thought about it, but during cat warmup there is basically no vacuum. That must be the cause of this. If you wait just one minute, like previously stated, the ecu will decrease engine load and it will start drawing vacuum.

UPDATE: After one week and one day, the dealer discovered the ECM was bad. Brakes work great on cold start now.
No need to wait 60-90 seconds every time you get in the car. Have the TSB done and you will always have brakes.
