problem #2

Sierra 1500

  • 116,000 miles


The contact owns a 1999 GMC Sierra 1500. While driving approximately 5 mph on a gravel road surface, there was no response when the contact depressed the brake pedal. It took excessive force just to stop the vehicle. Prior to the failure, the contact noticed that the stopping distance increased. There were no warning indicators illuminated on the instrument panel. The failure occurred intermittently. The vehicle was taken to an independent mechanic for diagnostic testing and the technician stated that the front wheel speed sensor was corroded and caused the failure. The vehicle is in the process of being repaired. The VIN was unknown. The failure and current mileages were 116,000.

Brake line running along frame to rear wheels ruptured when shifting from park to drive. Shift interlock requires brake depressed to shift from park to drive. Brake lines running from firewall to rear of vehicle along inside of frame rail are corroded and soft so badly as to need replacing. Like vehicle in shop for identical issue. When brake line ruptured, there are no brakes on vehicle at all due to a single reservoir vice twin reservoirs on most vehicles to separate front and rear brake systems. Brake line possibly made of material unsuitable for long term usage. Brakes lines also are place in an area that will collect corrosive material from roadway from vehicle tires. No crash, but $600 required in repairs. If moving when brake line ruptured, there is high probability of severe crash.
