Not hating on the dealer, but on GM. Chinese steel for brake lines? Aside from that, it's my understanding that new pre-bent brake lines are not available from GM, so someone like me is going to have to bear the labor cost of having a dealer tech make up new lines.
In any event, I've changed my mind about doing a partial fix myself. I drove the truck this afternoon to see just how dangerous it is. Rear brakes only, of course. And the ABS is probably losing its mind because the left rear is locking up on any heavy application. I just hope I can get it to the dealership without rear-ending anyone.
