Sorry but this is your problem and not GM or any other mfg. This is not limited to trucks but if they are used in winter weather where a lot of salt is used then this will happen. I've replaced brake and fuel lines in GM ford trucks and cars over the years. No big deal just cut out the old and replace with the new coated flexible steel lines.

Most of larger cities now use DE icing liquid and is more corrosive then the salt that was used. There environmental friendlier then salt but a killer on metal and especially cars and trucks. For the rusted brake lines, just have them replaced. Just another section in your maintenance scheduled and don't forget to inspect your transmission line also, there also common to corrode and a simple line replacement can save you a transmission replacement.

As for that person in Detroit trying to stop his pick up truck. Would of been better if he placed it in to neutral and use what they call emergency brakes (parking breaks or some who don't know what that is).

I just wanted to update this post. Apparently, there are few other GM truck owners that are complaining to the NHTSA about rusting/corroding brake lines. The NHTSA is investigating 6.2 million GM truck for the same brake line problems and upgraded their investigation last year.

Check out these links:

http://www.insideline.com/chevrolet/...e-problem.html

http://trucks.about.com/b/2011/08/01...-gm-trucks.htm

http://townhall-talk.edmunds.com/direct/view/.f0d4fe5

Feel free to do a Google search on "GM brake line failure."

I guess the government is dragging its feet until either more people die, or until GM figures out how to fix 6.2 million trucks for an average cost of $2000/per vehicle for a whopping $12.4 billion dollars... Ron

Well it's getting worse with my front end sagging so I'm having the shop inspect the front end for other possible damage. I'm looking into a leveling kit, new keys or what ever. My control arm is resting on the bump stops and the other day I hit a bunch of pot holes on the highway and it was so violent I was almost out of control. Winter is coming and I'll be driving the truck full time, and want it safe. I'll let you know how it comes out

I just wanted to update this post since GMC has not been forced to recall the vehicles yet and still doesn't manufacture replacement brake lines --- But, Classic Tube does! I just bought a complete set of stainless tubing, pre-bent with double flares and stainless fittings for $299 from Summit Racing (eight pieces I think) - to save shipping expenses. The kit looks impressive and I'm going to start replacing them tomorrow - weather permitting. Check out their web site: classictube.com because they make kits for most GMC trucks. And be careful. If you take your truck to a GM dealer, they may use these brake lines and charge you for custom bending... Ron

Why not just buy generic 1/4 in tube and bend it yourself? I think 15 ft costs about $30 . . . $300 for a prebent kit? Yeah, forget that!

Ran into this issue with a 2005 Silverado. Beautiful truck with no body rust but the brake lines were rotten from road salt.

Learned my lesson by keeping the underneath clean and sprayed down on the next truck.

To keep your tk from rusting out (or slow it down) just go to the car wash once a week and get the under cariage wash. so you may spend 200 bucks over the winter but the tk will last you 3 to 5 years longer. cheep if you ask me.
