Service advisor at local Chevy dealer, while trying to diagnose a vibration problem in my 08 TBSS, came across a TSB that describes my symptoms (intermittant vibration) and requires the replacement of the brake booster and master cylinder with updated parts. Since I am at 38,000 miles (out of warranty) they want ~$1,500 to do the work (!!!!). Is there anyone out there with access to TSBs that could check into this? BTW, aftermarket booster and master cylinder looks like about $150.

Did anybody find out about this? My TB has a very similar issue but the dealership can't figure out the problem.
