| Brake Hoses, Lines/piping, And Fittings problems |
We developed a significant leak in a rear brake line of our van. The leak did not lead to a loss of control, but the brake reservoir was nearly empty when I discovered the issue. The leak was discovered based on a large spot left on our driveway under the van. The vehicle was probably driven about 50-100 miles (one to two days) after the leak developed but before the issue was discovered and addressed. While fixing the problem, I found that the leak was due to an assembly error. The van's fuel filler down-pipe has a worm-gear clamp that was not properly clocked. This caused the clamp to rub one of the rear brake lines and wear a hole in it. I sent two pictures showing the clamp and brake line as I discovered them. I also sent a picture of the damaged line after being removed from the vehicle. The van had about 87,000 miles when the leak developed.
