Sierra 3500 8-cyl Diesel

  • 76,554 miles
My 2005 GMC Sierra 3500 crewcab with less than 77,000 miles on it experienced a ruptured brakeline. As I commenced going out my driveway the brake pedal felt mushy then went to the floor. Thank-goodness this happened in my driveway opposed to out on the road! brake line was rusted and rotted through causing a rupture in the line and brake failure. This vehicle is not routinely driven but used for hauling a horse trailer, trips or server weather winter driving; thus the low mileage for it's age. Cannot haul a thing without brakes as the undersized braking system on this truck barely stops itself under normal braking conditions. It is kept clean, dry and stored in an open front building. Since my incident a friend of mine with a very similar truck (maybe a year or 2 newer) experienced the same scenario. Fortunately, theirs happened as they were backing up to park at a campground and not out on the road either. Updated 1/8/2103
