Brake Drum Wheel Cylinder problems of the 2004 Chevrolet Silverado 2500

While driving under good conditions, sunny, dry road surface, approximately 65 degrees, asphault conditions excellent, not in traffic, no cars in front of me, no cars behind, the truck was empty and had only one person, the driver. I started to slow for an intersection and the brakes did not respond. The pedal went all the way to the floor. I was at least 400 ft from a traffic light equipped intersection at the time. I was able to down shift. The truck is equipped with some very low gearing for towing and by shifting down through the gears I was able to stop before the intersection. The brakes had very little stopping power left. There was no indicator that I was losing brake fluid pressure. However had I been on a highway, the truck fully loaded, in heavy traffic or on a big hill this could have turned out much worse. Reviewing the brake lines you could see that they were uniformly corroded on all exposed lines. The corrosion is heavy and it makes it difficult to determine the surface condition of the brake line. A leak had developed at a bend, in the line, just under the master brake cylinder. You really cannot see the leak due to the surface condition. You know it is there due to the visually seeing the brake fluid spurting out. All of the brake lines on the front end of the truck must be replaced and due to what I would consider defective brake line material I will have all of the lines replaced. I state that I feel they are defective or of extremely inferior quality do the fact that other lines in the truck show no corrosion at all, such as the ac lines, the lower transmission lines, lower gas line, these while tarnished are not corroding. This is the first failure of this type on the truck. Previously I had an exhaust gasket break and the alternator fail all other work has been maintenance type work such as oil changes. I purchased the truck new.

Engine on passenger side all rusting exhaust manifold bolts rotted and broke off causing an exhaust leak that effects sensors. Brake lines just bellow that rotted and just broke yesterday. Luck ally I was only in my driveway at the time, ironic thing was I just left the shop for my safety inspection, sullivan tire derry nh 03038 should report them as well. This truck has a very severe problem with all parts on the passenger side of the motor rotting my repairs for all rotting parts 2100. 00 these problems are unacceptable and should be fixed by gm . Looking and reading online I am not the only one with these problems. Seems to be happening on most all there 8 cylinder trucks and SUV.
