GM can say what they want, my truck has not been driven in snow or salt. It is just poor quality brake lines, and other steel lines on vehicle. I was told by the repair facility that my fuel lines were rusting very badly also, and that it was a common problem for Chevy trucks.

I have talked with other owners that have experienced the same failure, and feel that it is solely the fault of poor quality material that GM has purchased from China. Because of this problem, and a few others, I will not purchase another Chevy truck. Quality has been sacrificed for a few dollars profit.

I still have a 1969 AMC vehicle with original steel brake lines, and a 1996 Vette with original lines. Both of those are fine, so why is my newest vehicle rusting so badly? You have failed your customers Chevrolet, may they all buy a better product in the future.

Luckily the lines failed in my driveway, after returning from town. Had to replace 5 of 7 lines using stainless steel. Hope this will do better. The two lines over the rear differential are a plastic and did not rot. Putting the lines in plastic clips is just a magnet for salt. GM should replace all lines with stainless steel. Do something smarter with the clip location... DON'T PUT THEM ON TOP OF THE FRAMERAIL BEHIND THE FRONT WHEELS!!! Also coat them with some sort of undercoating to keep the salt from coming in contact with the metal.

Well, I bought the truck in March 2012 with less than 50,000 miles, had been garage kept. I had to replace both front hub assembly's within 6 months. This is when I had to remove my wheel cover, I noticed all of the left front frame brake lines were rusted almost into. I bought enough line at KOI to repair the severely rusted lines and used compression fittings to install. and bled brake system. I had to bleed the brake system one more time within a month.

I moved to Florida September 2014, the lines had rusted enough since the prior work to have rusted through again in two places. I have had to repair them in the same manner. I have recently bought all new front lines from the ABS Module to the Master Cylinder and to the front to wheel connections at the brackets where they tie into the rubber lines. This time bleeding the brakes has been a challenge. I am going to try and bleed them once more and if need be take my truck to a dealer near by to get it bled.

I have been in maintenance most of my life and never have seen exhaust or brake lines rust in this manner, kind of reminds me of the old Toyota beds rusting off the truck completely leaving the cab and frame! I can remember when I was young how much pride went into making a vehicle and now it's like it's just a matter of pushing them out the front of the building to get $40 to $50,000 a vehicle and so many issues occur with cheaper used parts or buying parts from the cheapest seller.
