Brake Master Cylinder problems of the 2001 Chevrolet Tahoe

Two rusted brake lines from the master cylinder to master distribution block under the truck caused the brake pedal to go to the floor at 50 mph and ran thru a 4 way stop intersection in a rural area, thank you jesus I'm alive, lot's of rust on the lower rockers etc. On both sides.

My wife was executing a turn, headed downhill, and stepped on the brake pedal, only to have it travel to the floor, and not stop the truck. I had been towing a trailer with surge brakes the day before, which would not have activated without being able to slow the vehicle. The problem was a failed front brake line from the master cylinder to the antilock actuator, resulting in a complete loss of front brake hydraulic pressure. I had also had it inspected recently and it passed safety. In locating the burst brake line, it was above the frame rail, in a spot I would not expect to be visually inspectable. I am replacing all the lines in the truck with the same material used by BMW and Volvo now, and consulting with my service tech about relocating the antilock actuator to an accessible area under the hood, for less line exposure to elements. This truck has been garaged most of it's life, and undercarriage washed after exposure to road salt. This is clearly a manufacturer defect. I have a 2006 Tahoe at work, garaged all it's life and rarely driven in wet weather, 60,000 miles, that had a rear brake line fail in 2011 or 2012. I'll file a separate complaint for that, but as a fleet vehicle, it's maintained meticulously. It's also essentially the same vehicle as my 2001, which had it's lines last longer, but still fail without warning. I want gm to recall these vehicles and fix the problem. Mine will be fixed with better materials, so I don't want a recall on mine, to have cheap cost-cutter parts installed. I want them recalled before someone like my daughter, an inexperienced new driver, has to deal with a loss of brakes during a normal life and maintenance routine of her vehicle.

Operating on the rear access road to a mall and noticed brake pedal almost went to the floor and it took a strong effort to stop the vehicle. Tried pumping brakes to see if pedal would rise, it did not. Checked brake fluid reservoir and it was slightly down. Looked under truck and no leak at all four wheels or on inside master cylinder cowl. Drove slowly to nearby mechanic and this time noticed dripping under driver side floor. Mechanic said I needed brake line replacement and am awaiting repair. Vehicle is well maintained, always parked on paved driveway, and waxed along with undercarraige car washes during the winter months. Purchased used from chevy dealer and found left rear backing plate had almost rotted off exposing rear axle seals which dealer replaced within week of my purchase.
