While under vehicle to replace gas filter it had become evident to me that the brake lines where they enter the ABS unit were fairly rusted. As I investigated further to areas not easily visible I had discovered that all the hydraulic brake lines are extremely rusted and imminent failure is evident. In mentioning this to a friend he suggest I check on line as he had heard of this problem. I was absolutely taken aback to see how common this failure is on these vehicles and that gmc is aware of it, yet they have never apprised me of this "possible condition"' and that I should take necessary action to prevent failure which could result in serious injury or death ! I have been a mechanic for many years and had worked for gm some years back. I have never observed such deterioration in a vehicle of this age. This vehicle is extremely well maintained in both periodic and preventative maintenance. I do not live by the water, we live in a moderate climate and vehicle is not subject to anything but normal driving conditions. I have (collectible vintage cars) oldest being 36 years old and the lines on all cars look new or in good shape. To my further dissatisfaction I had contacted gmc and they deny any knowledge of this problem or condition. I think all parties concerned should consider the possible catastrophic outcome of this component failure and also take into account the size and weight of these vehicles and the possible secondary consequences in an accident and take immediate remedial action.

Vehicle failed to stop due to brake failure, after pulling over the disabled vehicle a quick inspection revealed rotted brake lines running to the ABS control unit which had failed under brake pressure causing immediate loss of braking with no warning or any mil light status prior to failure. All the front brake lines were heavily corroded and all needed replacing before the vehicle was usable.

After two previous "repairs" (one a recall), our gmc ABS brakes are now malfunctioning for the third time. The ABS brake system activates on dry pavement at slow speeds, resulting in a longer than normal stopping distance. On numerous occasions, collisions have narrowly been avoided as the ABS brake pedal "chattering" prevents normal braking at crucial times.
