Brake and fuel lines are corroded. I learned yesterday from win kelly Chevrolet in clarksville, md that my brake lines are so corroded I should replace them immediately. Also observed were rusty fuel lines. I, and many other Suburban/Silverado owners apparently agree, that this is design flaw and should be resolved by a manufacture recall. This was my first GM product; all others were Dodge. I never had this issue with any of the 17 other vehicles I've owned over the past 34 years. If the corrosion is that bad I'd like to know why it wasn't noted in previous "bumper to bumper courtesy inspections".

Started engine, depressed brake pedal to shift into reverse. Brake pedal goes to floor with no pressure, brake and stability warning light go on. I back up, then go into drive, travel about 50 feet, apply pressure on brake pedal and again no pressure on pedal, Suburban slowly stops forward movement on level surface. I return Suburban to parking area and turn off engine, call service shop and make appointment for repair. Next week, 4/22 slowly drive Suburban 1 mile to repair facility for service. 4/23 repair manager calls to tell me that all the brake lines are excessively rusted.

Went to move vehicle to attach landscape trailer. Brakes went down to the floor. Upon investigation, found brake fluid on ground from driver side right front. Had vehicle towed to repair station and asked mechanic to replace brake line and check all other brake lines. Mechanic ended up replacing 80% of lines due to corrosion. This could have ended up resulting in an accident if the vehicle was moving with the trailer attached carrying atv's. in addition, the cable holding the spare tire had to be cut in order to get access to rear brake lines. The cable was rusted meaning that a tire could not be changed in the event of a flat.
