The brake lines in my 1999 GMC Sierra blew out, and I was barely able to stop the truck before entering a busy highway from my driveway - the brake pedal went all the way to the floor, providing very little breaking power and taking a much longer time to stop and a much longer distance to stop than normal . I was informed that my brake lines had completely rusted out, needing full replacement, which I had done last week at considerable expense. It is unconscionable that gm knew about this problem and failed to inform owners of their vehicles to have their brake lines inspected! I have owned this truck since it was new, and my address has not changed since it was purchased, so my address is in their files.
