Total brake failure after a long trip. *tr the consumer stated the brake failure was a result of rusted brake lines. Updated 05/08/12
All of the brake lines are completely rusted out. My wife had a complete brake failure while driving my daughter to school. Brake line over frame leading front to back failed and completely emptied the master cylinder of brake fluid, result car would not stop. This must be made into a recall, as the possibility of a major accident and loss of life is very probable.
I have a 2003 gmc yukon denali with approximately 12k miles when the brake lines corroded and caused brake failure. No accident,no injuries . It seems like the whole undercarriage is corroding. Vehicle was taken out of service to be repaired. Seems to be a safety issue of importance.
