Brake Master Cylinder problems of the 2006 Chevrolet Silverado 1500

Nephew borrowed my truck. He was in motion and tried to make a left hand turn on a city street and realized brakes had failed. He wisely continued straight till it slowed down enough and he made a right hand turn onto a road and pulled into a parking lot behind a housing project. He used a snow bank/boulder to stop the truck. Luckily no one was hurt. Truck was towed back to my house. I do my own repairs. After inspection it was determined that one of the supply lines from the master cylinder into the abs module had ruptured. There was complete failure of the braking system after a single push on the brakes. The truck is 11 years old. How can the brake lines be rusting out. There is a serious issue and a serious flaw with this design. I'm attaching 2 pictures for your observation. Gm should be held accountable for fixing these bad designs. Is this another cheap solution like the ignition key problem that cost countless lives? there should be the utmost action by this agency to hold gm accountable. This abs module should be up in the front hood like other manufacturers do. Not under the cab in a wet environment. Shame on gm.

Brake lines are rusting away. I noticed a soft brake pedal, on my way back to st. Louis from atlanta, GA. I noticed fluid under the truck in my driveway after I got home. I started looking around the truck. The master cylinder was low on fluid. No warning light came on. I noticed fluid under the drivers side door. It was brake fluid coming from a rusted thru brake line. After inspection, all of the other brake lines were badly rusted. The repair(reichers auto and tire-washington, mo) shop is replacing all of the brake lines due to heavy rust. Cost is going to be over $800.

Leaving my drive way my brake peddle went all the way to the floor. I had to use emergency brake to stop truck. After checking for problem I found that the metal brake line from the master cylinder to the brakes had rusted through in the engine area and brake fluid was being sprayed on the manifold. (if engine was hotter their could have been a fire. ) truck is sitting in my driveway still not fixed.
