My wife was driving our 2004 Chevrolet Avalanche with our 3-year-old son in the back seat. When she tried to stop the vehicle, the brake pedal went to the floor, and it took a great distance to stop the vehicle. She was close to home, so she returned and parked in our driveway. When I got home from work, I filled the reservoir with brake fluid, which was instantly drained. I looked under the door on the driver's side to find the brake fluid pouring out on to my driveway. I had the vehicle towed to a local repair shop. Estimated cost is $1600 to replace the brake lines and the cylinders that have become fused to the lines by the massive amount of rust. I do not live in an area of the country where roads treated for snow is a concern.

Tl - the contact owns a 2004 Chevrolet Avalanche 1500. The contact stated that while attempting to brake from 5 mph, the brake pedal abnormally traveled to the floorboard. The contact inspected the vehicle and discovered that the brake line was rusted, causing all of the brake fluid to leak out from the vehicle. The vehicle was towed to a mechanic for further inspection and repairs. Neither the dealer nor the manufacturer was notified. The failure mileage was 80,200. Kmj.

Rear hydraulic brake lines rotted and leaked fluid causing loss of braking. Last year I had to have the rear brake calipers replaced due to excessive rust and rot. The mechanic performing current repairs stats that the front hydraulic lines are rusting and will have to be replaced soon. The front calipers have rotted out bleeder valves. The front calipers will have to be replaced as a result when the front hydraulic lines are replaced. Check engine light was diagnosed to an evaporative emissions system leak. The leak was traced to a damaged plastic fitting connected to the fuel pump at the top of the fuel tank. The fuel pump metal was rotted causing the joint to expand damaging the fitting and causing the leak. I do not trailer a boat and the truck has never been immersed in salt water. I have been driving for over 40 years and have never had this amount of undercarriage rust and metal damage on any vehicle I have owned with many more miles and years of service.

I was backing out of a parking space and as I went to stop the brake pedal went soft as soon as the brake pedal was depressed, going to the very nearly to the floor. (normally the pedal stays several inches further above the floor. ) the service brakes light came on along with the truck's warning chimes. I got out of the truck and saw large amounts of brake fluid dripping off the undercarriage near the left side rear tire. About 1 to 1. 5 hours earlier, when I was parking the truck, the brakes operated normally. A Chevrolet dealer had to remove and replace that brake line. Approximately 3 months prior to this incident the Chevrolet dealer who normally services the truck alerted to me to extensive rusting of all of the truck's brake lines. They did not think there as immediate danger of a brake line failure, but strongly recommended that all brake lines be replaced prior to the oncoming winter where corrosion might become accelerated.

The contact owns a 2003 Chevrolet Avalanche 1500. The contact was driving 5 mph when the brakes were depressed to the floorboard and the vehicle failed to stop properly. The contact mentioned that after inspecting the vehicle he noticed that there was brake fluid leaking from the vehicle. The vehicle was not taken to the dealer. The manufacturer was contacted. The vehicle was not repaired. The failure and current mileages were 190,000.

I noticed that by brakes felt like I was losing braking power. I suddenly was able to push my brake pedal to the floor and my braking was reduced. I got home an noticed that my main brake line was severely rusted and fluid was squirting out of a pinhole of my brake line. I searched the internet and found that this is a common occurrence among Chevrolet truck owners.

Stepped on the brakes to stop for a stop sign at a major intersection and my brake pedal was good a first then completely sunk to the floor. The truck stopped in the middle of the intersection that was thankfully void of traffic. My wife and I were a bit shook up. It could easily been worse. We carefully traveled to the nearest service station and were lucky to get flatbedded to a local Chevrolet dealer. Memorial day 4pm in georgia, I did not have high hopes. The service people examined the truck and it was apparent that my truck had catastrophic failure of the brake lines. I thought it was a master cylinder due to the complete loss of fluid. While we waited for tow truck I purchased brake fluid and filled my completely empty reservoir, had my wife step on the brake as I watched the fluid just pour out from the front drivers side area near the frame.

I was traveling at approximately 35 mph when a car in front of me stopped short and I was forced to apply heavy brake pressure. The brake pedal went almost all the way to the floor I was forced to steer off the road in order not to hit the vehicle in front of me, the Avalanche had almost total brake failure. Upon inspection of the vehicle it was found that the brake line had burst due to severe corrosion and the brake fluid was pouring out of the vehicle right above the rear axle.

Rotting brake lines in the vehicle listed above, noticed brake fluid leaking from lines. Corrosion so bad requires all lines to be replaced. Dealer also damaged brake controller during repair and charged me the replacement cost.

I was driving down hwy 316 and began approaching a red light. When I attempted to begin stopping for the red light, my brake pedal went all the way to the floor and the brakes didn't seem to be working. Luckily I was able to safely pull off the right side of the road and was able to avoid hitting any other vehicles or objects. I then pulled into an empty parking lot about 50 feet away. When I got out of my vehicle and starting looking around I could see fluid dripping on the ground next to the driver side front wheel. I then was able to find that the fluid was brake fluid and it was coming from a pinhole sized leak in the stainless steel brake line coming from the master cylinder and going to the abs system. After closer inspection I have discovered that all my steel brake lines are severely rusted. There were no warning signs, lights, bongs, or beeps until after my brakes failed. My brakes would barely work,the pedal would go to the floor and I would only be able to slow my vehicle down enough to shift into neutral and then shift into park to completely stop. I consider myself and my family extremely fortunate that we were able to avoid a crash and were not harmed or didn't harm anyone else. After this occurred I starting doing research on the internet and discovered that this has become a major issue with Chevrolet vehicles in the salt bed states. I live in georgia, but my chevy Avalanche is from a salt bed state and was only recently brought to GA.

Corrosion of hard brake line from the master cylinder to the rear distribution module resulted in loss of braking capacity when the brake line failed resulting in fluid leakage.

Without warning, while driving last spring, 2011 the brake line broke and I lost brakes suddenly while stopping for traffic. The dealer replaced steel brake line on left side of rear axle at my expense. Today, while stopping hard in traffic, the peddle suddenly went to the floor and I lost all brakes. The steel brake line along the frame, from the front of the truck to the rear is leaking fluid from a burst in the steel line. Again, no brakes. I purchased this truck in 2002 and its has always been to the dealership for regular service.

The brake lines on my 2002 Chevrolet Avalanche are severely corroded (rusted). I already had a ten-foot section of the tubing replaced this summer. Since a 'hard stop' last week, my brake pedal now has a soft mushy feel, and braking distances are longer. Another section of the brake lines seems to have 'burst' and is leaking brake fluid. I'm taking it back to the shop to have the entirety of the brake lines replaced. Hoping I'll eventually be able to get the cost of this repair covered by gm, as I don't think these should fail (ever), even after the warranty has expired.

Sudden loss of brakes upon brake application. Brake fluid leaking from brake line where brake line connects to brakes.

Letter from congressman carney on behalf of constituent re his concerns about rusted brake lines in gm vehicles. The consumer experienced sudden and unexpected brake failure due to a metal brake line that had ruptured and was rusted. The brake pedal went all the way to the floor. Fortunately, the consumer was able to bring the vehicle to a slow and safe stop. An inspection revealed all the brake lines under the drivers side door were severely rusted and were leaking braking fluid. The dealership replaced the brake lines to the front brakes, the master cylinder, abs control module as well as the rear backing plates and right rear caliper that were severely rusted.

First time brake line under drivers door rusted out, leaked brake fluid and had to do steer to avoid another vechile stopped for a red light. Had truck towed to a shop for repairs. Mechanic told me this was common problem with gm trucks. Second time lucky I was on my property moving 1000 lb trailer around and notice brakes not working properly. Got out and looked under truck and saw a stream of liquid from around area of front axle. Took truck to nearest mechanic. I stopped by the next day and the mechanic had truck up on lift and came over to me and said "you need a new truck" he said the lines are rusted (brake, fuel and transmission). I also have 2002 Jeep wrangler with 180k miles and have not had to replace brake lines like I've had to do with my 2002 chevy Avalanche. I am the original owner of bought them.
