We took our 28 ft camper to be repaired which consisted of driving on interstate an at a high rate of speed but doing the speed limit. On our way home we were no longer hauling the camper because it had been left behind for repair. I thank god for this because I would hate to think what would have happened if we were hauling the camper on the interstate and the brake line would have broken then. When we were almost home I felt something was wrong with the brakes. I had to press them all the way to the floor to get my vehicle to stop. I was close to a advanced auto so I drove very slowly and stayed far from vehicles so that I could make it there for them look to see if I was low on fluid. But when I turned into their parking lot immediately after I put on the brakes to park it the brake line broke. I had to have my vehicle towed to a local dealership where I had to have repairs done. Not only the brake lines were changed but the calipers also. The bill was just under 5 thousand dollars. I called GMC all they did was call the dealership to make sure everything was done. Which was no help to me. I could have taken care of that myself. I believe this is a great injustice to GMC owners that they know of a situation and would let us use these vehicles to haul our children on camping trips putting their safety in danger. I will not purchase another GMC vehicle. Also my extended warranty ended a few weeks before. Although I was told they would not have covered it . I also bring my vehicle for oil changes as required to the dealership which they do check other things as a routine. I cannot understand why these auto repairmen didn't catch this . There is no reason this should have happened to this vehicle. . . When your brakes go out you looking at a major danger to yourself and others.
