Where I stand is that I have been patiently waiting for The Chevy dealer that has it now to remedy the problem. The problem showed itself for the dealer a few times, but as soon as it came, it went. After all the tests everything showed normal, but just today the service manager almost his another car in his lot when the brakes failed. When he tried it again it worked fine. They are all stumped. The hydroboost pump was replaced on the first Avalanch when it failed this past winter. The hydroboost pump powers the steering and brakes. I'm waiting for the 2003 Avalanches to maybe trade this one on a new one. I haven't given up on the Avalanche yet.
