Brake Hoses, Lines/piping, And Fittings problems of the 2000 Chevrolet Express

1 of many issues with this van. 62000 miles. Rear brake line blew, luckily in my driveway. Upon inspection all the lines in the rear need replaced. Funny thing is the bottomside of the van is as clean as can be. I bought this van 2 years old with 24000 miles, I'm extremely picky about my vehicles and am a maintanence nut. Always garaged, waxed numerous time a year, synthetic fluids. . . . . Here is a list of what I remember has gone wrong with this van. Intake gaskets, twice. Front bumper reinforcement rotted out 40,000 miles, rear chrome bumper rotted 40,000 miles, ac line corroded thru, transmission grenaded at 42,000 mile(sun shield failure?), left window motor has dead spot in it from day 1. Remember this is a very well maintained, always garaged, mainly driven for vacations. Gm is well aware of all these issues and wouldn't help on any.
