Brake line corrosion caused rear drivers side steel line to burst and lose most of the truck's braking ability. Luckily i was driving slowly at the time. In addition to the line that rusted through, all lines will need replacing after further inspection. *tr

I was backing up a trailer with my 2003 gmc sierra and tried to stop when the brake pedal went to the floor and did not stop. Checked out the brakes and found that the brake lines are rusted bad and one had failed. I found out this is a common problem with this truck for that time period. Reading about other complaints and there are a lot of them . This is not normal and very dangerous and there needs to be a recall…

You must take action on the gm brake lines in the early 2000 trucks. The corrosion is not normal compared to other vehicles. Either the metal is thinner or there is something in the metallurgy allowing increase corrosion. With the worst winter in recent memory, these brake lines were subjected to more salt than ever. I realize that there are two sets of brake lines and if one of them fails the vehicle still may stop…

Had there not been signifigant snow on the ground, this maneuver would have been impossible. The…
