Got hard on the brakes to avoid a deer that had jumped out of a ditch and the brake pedal went to the floor and brakes gave out. Dealer replaced all the rotted lines to the tune of 1250.00.

Brake failure by model year
What owners say
Brakes failed as brake line corrosion allowed fluid leak. This was first of multiple line failures in the last three years. Three different factory lines failed then one transmission line. This truck is not used during winter and was under coated multiple times. No other part on this truck is corroded nearly as much as every steel line on it, including the gas lines( also replaced just last year) truck runs and drives excellent except for this corrosion problem.
I was pulling my horse trailer and went to stop at a stop sign and my truck brakes went out and I could not stop. I ended up being pushed into traffic and almost went off a cliff. My step dad came and got my trailer and we hauled my truck back to his place. My dad and step dad started looking at it and my entire brake line is rusted out? I have noticed several websites stating numerous incidents and recalls? I need help!
While attempting to slow the vehicle to exit the highway, the brake pedal went to the floor and there was limited braking. The vehicle had to be slowed by down shifting. After the vehicle was off of the highway, the brake warning light illuminated. The vehicle was taken to the dealership where mechanics found that one of the steel brake lines had rusted and ruptured causing the brake fluid to leak and the reduction in braking ability. All of the steel brake lines are severely rusted and need to be replaced due to concerns of additional failures.
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.
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 calipers replaced they were totally covered 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.
