My wife and daughter were driving on the highway.when they went to exit, the brake pedal went to the floor.after I got it home I followed the brake fluid trail into my garage.had it inspected by my mechanic and two of the brake lines were rusted through and the others were on there way to failure also.too big of a job for him so I made an appointment at the chevrolet dealer for next week at a price of around $1300 as quoted.the dealer told me there is a repair kit for this because of so many cases of premature rust failure but gm will not incur any of the costs or admit a safety issue.the outrageous cost of the fix is one thing but the safety of many is totally another.

Brake line eroded away on a very well taken care of 2004 gmc yukon denali. Nearly collided with another vehicle going over speed bump and had absolutely no warning! My pedal went to the floor and the only way ii avoided collision was putting the truck in neutral and stomping on the parking break. For a vehicle that new costs over 50000 dollars to fail at such a low mileage and not even close to a decade old is completely unacceptable. This vehicle rarely seems inclement weather and is covered with a nearly 500 dollar california car cover.
