Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

My wife was driving our 2004 Chevrolet Avalanche with our 3-year-old son in the back seat. When she tried to stop the vehicle, the brake pedal went to the floor, and it took a great distance to stop the vehicle. She was close to home, so she returned and parked in our driveway. When I got home from work, I filled the reservoir with brake fluid, which was instantly drained. I looked under the door on the driver's side to find the brake fluid pouring out on to my driveway. I had the vehicle towed to a local repair shop. Estimated cost is $1600 to replace the brake lines and the cylinders that have become fused to the lines by the massive amount of rust. I do not live in an area of the country where roads treated for snow is a concern.

Started my Chevrolet, started backing up down an incline of my driveway, "service brakes" indicator illuminated. Brake pedal sank to the floor. No brakes. Opened hood and the front left wheel brake line (cheap steel) was shooting brake fluid everywhere and all over the engine. It's going to a Chevrolet dealership tomorrow for repairs.

The contact owns a 2004 Chevrolet Avalanche 1500. The contact stated that while attempting to brake from 5 mph, the brake pedal abnormally traveled to the floorboard. The contact inspected the vehicle and discovered that the brake line was rusted, causing all of the brake fluid to leak out from the vehicle. The vehicle was towed to a mechanic for further inspection and repairs. Neither the dealer nor the manufacturer was notified. The failure mileage was 80,200.

Brake lines corroded to the point of failure causing a loss of braking at 35 miles per hour. Dealer will replace entire trucks brake lines extensive repair. Personally know a friend with a 2002 Chevrolet that had the same problem. The repair center he repaired his truck at informed him that they replaced four other Chevrolet trucks brake lines in the last six months. I have been driving for forty years and never replaced brake lines on a car some with over 150,000 miles on them.

Rear hydraulic brake lines rotted and leaked fluid causing loss of braking. Last year I had to have the rear brake calipers replaced due to excessive rust and rot. The mechanic performing current repairs stats that the front hydraulic lines are rusting and will have to be replaced soon. The front calipers have rotted out bleeder valves. The front calipers will have to be replaced as a result when the front hydraulic lines are replaced. Check engine light was diagnosed to an evaporative emissions system leak. The leak was traced to a damaged plastic fitting connected to the fuel pump at the top of the fuel tank. The fuel pump metal was rotted causing the joint to expand damaging the fitting and causing the leak. I do not trailer a boat and the truck has never been immersed in salt water. I have been driving for over 40 years and have never had this amount of undercarriage rust and metal damage on any vehicle I have owned with many more miles and years of service.

Put on brakes to avoid car slowing in front of me. Brake pedal went to the floor and had almost no brakes. Had to swerve drastically to avoid hitting the other car. Mechanic checked the truck the next day and found corroded brake lines had failed.

Turning the corner without any notice, the brake line apparently broke and the brake pedal went to the floor. Brake fluid went everywhere- was able to pull over and use the emergency brake to stop, but god forbid if I was on a freeway or was pulling my boat! could have been catastrophic! upon further investigations, all of the brakelines showing under the driverside wheel well are corroded badly and will need replaced. I have owned alot of cars/trucks and never had to replace a brake line. The costs I have been quoted are upward of $1500 to repair due to the poor design and that the parts have to be ordered specifically for this vehicle. This should not be happening on a 2004 vehicle with the low miles it has.

Leaving the yankee stadium parking lot in the bronx. Traffic was heavy! the traffic was stop and go. Upon stopping I felt the pedal go to the floor and smelled brake fluid. I pulled over and notice the split in the brake line near the chassie. I then had the vehicle towed home. The truck is a 2004 Chevy Avalanche with 60,213 miles on it. The brake line was split on the driver side chassie. It was not the rubber line going to the caliper but the stainless line feed the system.
