Brake Hoses, Lines/piping, And Fittings Problems of GMC Suburban

Complete loss of brakes coming up to a stoplight in moderate traffic. Widespread heavy corrosion/deterioration of brake lines resulted in rupture of brake line over left rear wheel. Emergency/park brake used to avoid accident. Clearly a materials defect in the brake system, in my opinion.

The brakes failed as I was approaching a stop sign. The brake lines were badly rusted, much worse than would be expected. This could have been very serious had it happened at a greater speed!.

While attempting to stop in a business parking lot, brake pedal unexpectedly went to floor, vehicle ran over curb/stop, damaging suspension. Cause of incident was determined to be a ruptured metal brake line, caused by severe corrosion. A second line was found to have small pin hole, which had not yet ruptured, but could have failed at anytime.

Brake lines rusting through; lost rear brakes first time (early 2008) and I had 2 brake lines manufactured that were of higher quality than original; this time lost front brakes - metal line started leaking rapidly; now have to replace all remaining brake lines to feel safe. Suburban 2500.

When applying pressure to the brake pedal pedal will unexpectedly fall to floorboard, and brake system will fail to stop vehicle. Brake pads and shoes/ rotors, and lines have been replaced, which has failed to effectively remedy the problem. Dealership has not examined vehicle for this problem. Please provide any additional information / documentation.

Truck pulls when braking. Tbs fix implemented with little to no improvement. Last time at dealer, dealer said GMC has problem with 3/4ton Suburban brakes but doesn't have fix. Nothing he can do. Truck has had combination valve replaced, rear shoes replaced, front pads replaced (5x total), calipers replaced, rotors replaced, tie rods replaced, idle arm replaced, steering box and pitman arm replaced, front brake hoses replaced, control arm bushings replaced, and aligned several times with no fix to the problem. Braking at highway speeds it is very dangerous. You don't know which way the vehicle will go and how hard it will try to get there. As an engine designer I find it amazing that gm has a handling/safety issue of this magnitude. This is a big truck to have such a controlability problem. Please help. A shaull.
