...did anybody see the "Out of Control" special last night on Discovery? There was one when a K5 was driving up a rather large rock (like 100 feet up) in Moab and on the way down, it losts its brakes , went off the side and flipped over- all caught on tape. It looked like a 75ish K5 because of the headlights and full top. The investigation determined the master cylinder had failed, thus causing the truck to loose its brakes. Then I think the extreme angle stalled the motor, so the driver lost power steering. Damn GM master cylinders! That has got to be the most scary feeling loosing control of a vehicle going straight down.
