Driving into driveway applied brakes , pedal went right to the floor no warning light or any indication of a problem got out of truck and found fluid dripping off frame by fuel tank. Ruptured line above tank on frame, other brake lines also look corroded. After some research I found this to be a common problem on gm trucks . Owners need to be made aware of this problem before someone is seriously hurt. I believe gm should be forced to repair the defective lines.
Was leaving my drive way and went to put on brakes and they made a hissing sound and peddle went all the way to the floor and brake fluid started pouring out, so pushed emergency brake and nothing happened there was no brakes. With help got truck back in drive way and got under truck where fluid was leaking and the brake lines were all rusted into. Thank god I didn`t make it down the road before they went out and hit or killed someone.
A break line ruptured resulting in loss of fluid and diminished breaking. Fortunately it did not result in a catastrophic loss in breaking at a critical time. The ruptured line is near the gas tank and at first appeared to be a gas leak. Upon inspection all break lines are substantially rusted and must be replaced to maintain safety. One rusty line could indicate damage or a single defective part. 100% of the lines being corroded to an unsafe level indicates substandard parts. The rear disc breaks have been a constant problem with corrosion of sliding parts resulting in calipers not moving freely. The spongy feel to the breaks was attributed to sticking of the rear calipers rather than a fluid leak. Annual lubrication and a total replacement of rear breaks has become normal practice. The poor rear breaks can lead one to not notice a slow leak of break fluid until a total loss of breaking action. The slight extra cost for corrosion resistant break parts could save lives.
