Brakes failed and I had to swerve into oncoming lane to avoid a rear end collision. Pedal went to floor and secondary brake system brought the truck to a stop. Investigation showed severe rusting of brake lines throughout the vehicle. The tragedy of this is that this truck cost over $60,000 and for probably $10 more at the time of manufacture, gm could have installed stainless steel brake lines or at least something with some corrosion treatment. This is a real ticking time bomb with all of the gm products on the use car lots that are about to rupture their brakes and cause an accident. I remember when honda had to recall for rusty fenders. Hello wake up!!!!
