1997 Dodge Ram 2500 brakes problems

I purchased a 1997 dodge 2500 ram pickup truck in november of 1996. Within a few weeks I experienced a brake failure when I hit the brakes hard. I managed to change lanes to avoid an accident and tried many times after that to get the brakes to fail. But it didn't happen again until almost a year later. Same result, no accident and couldn't repeat the problem. I brought the vehicle to the dealer for some warranty work and reported the brake failure to the service manager.

Tl*the contact owns a 1997 dodge ram 2500. The brake lines have rusted in three places. The failures occurred near the master cylinder and the frame rail. While approaching a stop sign at approximately 10 MPH, the brakes failed. The brakes also failed in his driveway and at a drive through window. The brake lines were replaced in parts since the dealer no longer sells the all of the original parts. The dealer diagnosed the failure and stated that it occurs as though it were normal wear and tear.
