1 Brake Master Cylinder problem

Failure Date: 01/12/2014

I was traveling in icy conditions (rain and 26 degrees) and was turning the corner to go into a local mall when I stepped on the brakes, the pedal went to the floor. There was no warning whatsoever and had to apply the brakes with both feet to coast to a stop. I added in a bottle of brake fluid into the master cylinder and had my son step on the brakes, and a gusher came out of the line right under the drivers door. In looking underneath the vehicle, all of the lines seem to run there and all look extremely rusted to the point where I can't tell which is bad. If this had happened 4 minutes before, I was traveling down an extremely steep grade and feel that both my son and I would have been killed. After searching the internet on this issue, it looks like this has been investigated by the NHTSA since 2010 with no findings whatsoever. This is absolutely in excusable. I'm not sure what I am looking for as far as repairs go but am really thankful that my son and I are still alive. What is it going to take to get a ruling on this? does someone have to die?.

3 Brake Master Cylinder problem

Failure Date: 03/22/2013

This is the second time the brake lines have failed on this vehicle and a report issued to NHTSA. This time, my son was driving and applied the brakes to stop at a stop sign. The brake pedal went to the floor. He went through the stop sign, crashed into a median that slowed him down, and ended up on top of the median. Thank goodness the truck was empty and no one was using the right-of-way at the intersection. Inspection showed yet another corroded brake line. This brake line was oem. The brake lines were replaced after the previous incident look fine and are not corroded. It appears that all of the brake lines need to be replaced to correct this safety defect. The consumer stated he experienced hydraulic brake failure at 51,848 miles due to corroded brake lines. The lines burst in an area that was weakened by corrosion and failed under normal usage and brake line pressure. There was no indication that failure was eminent. The dealer replaced the rusted brake lines from the master cylinder. Updated 04/03/13.

7 Brake Master Cylinder problem

Failure Date: 04/02/2010

While stopping at a stoplight a mile from my home, I noticed the brakes seemed soft on my 2003 chevy Silverado 2500hd diesel with 95,000 miles. After coming to a stop I pumped the brakes and felt and heard the brake line burst as the pedal went to the floor. The brakes were completely gone. Using the emergency brake I was able to turn around and make it back to my home where I parked the truck and it hasn't moved since. I crawled under the truck and discovered that the rusty brake line going from the master cylinder to the abs unit just below the divers side door, had bust open and failed. The other brake lines also appear very heavily rusted, and after this experience I would not drive the truck again until they are all replaced. In all my years of living in new england and owning several gm vehicles, I have never had to replace brake lines due to rust or corrosion. I feel very lucky not to have been moving when that particular line burst. I would have been unable to stop as it caused a immediate and complete failure to the braking system. It seems clear to me that a higher quality brake line should be used to prevent this from happening.
