Two problems related to brake disc caliper have been reported for the 2004 Chevrolet 1500. The most recently reported issues are listed below.
On July 22, 2015 I was driving my 2004 chevy silverado 1500 and when I went to stop at an intersection the brakes failed and I had go through a stop sign. I had to hit the emergency brake to get the truck stopped. I was lucky it happened in a housing sub division and not on an interstate because someone could have been killed. I was close to my mechanics garage and was able to get it into the garage where I was informed that all of my brake lines were completely corroded and rusted through he also informed me that a brake caliper needed replaced due to all of the brake line corrosion. The mechanic also informed me that all the fuel lines were corroded and also needed replaced. The mechanic told me he has replaced brake lines on several silverado's all due to corrosion. This truck only has 65,665 miles on it and was seldom driven in snow. I'm not sure why there is not a recall on these trucks. If my wife or one of my kids was driving this the outcome could have been different. The total cost was over $1400. 00 to get all of the lines replaced something needs to be done before someone gets killed.
I was on my way home from work, traffic came to a sudden halt. I hit my brakes, which felt funny, so I pumped and the peddle went all the way to the floor. I swerved into an apartment complex with a circular driveway and thank god there were no cars or people in my path. I used the parking brake to stop my truck. Contrary to the statement being made by gm, that you still have brakes, this is bull, the peddle goes to the floor. After being quoted from the dealer, that my truck needed rotors, calipers, (of which this is the third time) pads, all fuel lines and all brake lines, with a total price of $5,600 plus, I decided to check for brake problems with gm trucks. I was shocked to say the least and then angry. Who the hell is believing all of the excuses from gm. I have been around cars all my life brake lines and fuel lines don't fail on this scale. I don't care what part of the country you live in. What genius decided it was ok to use steel tubing for something as important as fuel and brake lines. Steelrusts. The numbers being quoted for failure, I'm convinced after reading all morning, are very low. Do people have to die for someone to admit they made a mistake and correct it? this goes for the ntsb, and gm.
