While driving down a 50 mph roadway there was a line of cars slowing for a vehicle to make a turn. When gently pushing the brakes to slow down, brake went clear to the floor and could not slow down. Truck was driven into the ditch to avoid rear-ending vehicles. This happened immediately without warning, all braking prior to this incident was normal. When taken to our mechanic, they advised the brake lines underneath were notorious for rusting out and failing, new stainless steel lines were then installed to correct the problem.

The component that failed according to the Chevrolet dealer is the "transfer case pump clips", which came loose inside the transfer case and wore a hole through the case causing the oil to come out. If I would not have noticed the oil on the back of my truck, I could have continued to drive the truck, which could have caused the transfer case gears to lock up the front and rear axles while driving and could have caused me to wreck, causing injury to myself, my family or someone else. I marked the area of the leak with a sharpie as depicted in the photos.

I had to replace the replace the housing on my transfer case as it wore a hole in and was leaking. At a cost of 1200 dollars due to myself catching it early as later with a fully disabled case would have been 2600 dollars. My mechanic who deals in transmission repairs told me this a very common problem for Chevy trucks from 1999 to 2006. He claimed he had done 7 transfer cases in one week and was actually replacing a fully wrecked one for 2600 dollars as I brought mine in to be worked on . It had worn a hole through the transfer case and was leaking. As this seems to be a serious defect . I feel it should have been under a recall and reimbursement should be in order for those who paid out of pocket for repairs. My mechanic also stated that he has replaced them at 35, 000 miles and on up. No rhyme or reason to when they fail or leak.
