Brake Hoses, Lines/piping, And Fittings problems of the 1999 GMC Sierra 2500

2 years ago I had all of the brake lines replaced because of failure due to rust at a cost of $1000. 00 I believe the cause was poor metal in the brake lines and the way the lines are attached to the body & frame help to cause the problem.

Truck was in shop for unrelated maintenance. Brake line failure occurred while moving truck out of service bay. Truck is currently undriveable. Mechanic indicated that this is common failure as lower quality material was used in the brake lines. Additional research on web indicated this is a widespread issue. This is the first I had heard of the problem. I am the original owner. I feel blessed that this failure occurred in a non-traffic situation. I frequently drive this truck in heavy traffic on I-94.

Dealer replaced rusted out brake lines in 2008. Dealer now says brake lines need to be replaced again. Brake lines for this vehicle are apparently made of a material that is extremely prone to corrosion leading to brake failure-which occurred to this vehicle.

I was driving my daughter to a friends house. When the pedal started getting soft ,it was just a 3 mile ride on 35 mph roads. By the time I got home I had no brakes at all. Had to have 5 brake lines and 2 brake calipars replaced they were totally coverd with rust.

I own a 99 GMC Sierra 2500. While pulling a 9000 lb trailer my brakes went out had enough time to down shift and use emergency brake to bring truck too a stop. Upon investigation I noticed the blown brake line and lots of corrosion on the under carriage of the vehicle this is something that needs to be addressed. I have owned older vehicles and have never seen such rust on the under carriage like this truck has. Especially the brake and fuel lines.

I have a 1999 gm pickup while 3 hrs from home I was coming onto a traffic signal when I applied the brakes I was not slowing down I had to use the emergency brake and lower gears to prevent running into the cars ahead of me, when I finally stopped and checked fluid I was empty the closest station was still miles away, lucky for me I was on FL st rd 710 20 miles from indiantown I stayed in the slow lane driving at 5- 25 mph until I could get fluid. I had this problem all the way home without crashing. Upon investigating I found that my brake lines have rusted out, I am now in the middle of changing them out as I can't afford a mechanic and now am having problems trying to fix so now I am out of work because of this. Last night I happened to be watching the news and seen this. If you would like to see the lines I have one off out of 4 lines my hope is a recall to have these fixed by someone that knows how if not I will do my best so I can make it to work.

1999 GMC sierra k2500 4x4. At just over 100k miles the advanced rust and corrosion on my steel brake lines is very bad. These are the hard galvanized lines that are in the engine compartment beneath the brake fluid reservoir near the frame, and the hard galvanized lines that run along the inside of the frame rail on the driver side (left hand side of the truck) from front to rear. This started a few years ago and has gotten progressively worse. The corrosion is in the form of rust that is flaking off in chunks. With the steel rusting and flaking away like this, it will compromise the integrity of the brake line, significantly reducing the ability for the brake lines to hold pressure, and at some point may ultimately result in brake failure. I have other gm vehicles with more miles that are older I've had since new and the brake lines have very little signs of rust and corrosion. I am not happy about this as I take very good care of my vehicles and this is the first gm vehicle that I've seen this happen. I will have to stop driving this vehicle to avoid the high accident risk potential the rusted brake lines have created.

Brake line burst. This is the second time, but a different brake line.
