Brake Hoses, Lines/piping, And Fittings problems of the 2004 Chevrolet Avalanche

Third brake line failure due to corrosion. Areas of failure are hidden from view above other components. Upon brake line failure, backup braking was inoperative in all cases. Vehicle was on a city street in motion attempting to stop. Brakes failed suddenly in all cases. Brakes were very noticibly inoperative before any indication on dash board. Pumping the pedal did nothing- the pedal went to the floor. Was told manufacturer no longer supplies brake lines for this vehicle.

All the frame is rusted and all brake lines and fuel lines, and front end parts rusted.

The contact was able to stop the vehicle. The contact noticed that a brake line was severely corroded, which caused a fracture in the brake line. The vehicle was taken to the dealer, but was not repaired. The contact stated that several brake lines were previously repaired. The manufacturer was notified of the failure. The approximate failure mileage was 141,000.

Brake line failure. I was approaching a stop sign and applied the brakes. The pedal went to the floor and the abs activated and I was not slowing. There was no cross traffic so I luckily avoided an accident. The brake line failed due to rust. Braking ability with only the rear brakes active was virtually nonexistent and there was no warnings on the display. I do not understand how the previous investigation into gm brake lines was dismissed.

My family and I was traveling on a busy road at 45 mph, when we had to come to a stop and our brakes did not work. We almost slammed in the back of the car that was infront of us. My husband had to push the brake pedal all the way down to the floor and turn toward the grass shoulder. Thank god no one was hurt. My husband checked under the vehicle and saw that there was break fluid running out of the brake line. There were no warning lights or warning sounds that our vehicle made until after he started the vehicle again and then the vehicle gave a warning sound and a warning light. We are contacting our mechanic tomorrow because this happened after 6pm. I have been reading the other complaints on the Avalanche's break lines and my husband said that I should also file one.

Yesterday,July 4th 2015 my 2004 Avalanche; with only 70k miles , the brakes failed. It was due to a rusted blown out brake line. I had no brakes driving on a mountainous road. I thought I was alone in this failure but after internet searching I find this is common problem with this vintage and model. I take very good care of my vehicles; underbody washing during inclement winter conditions , I was appalled at the underbody rust. Having other vehicles of similiar age and mileage with no rust, I felt gm has used inferior materials. Gm should stand up and admit their use of substandard materials and offer remedy. They should know that as a consumer if they don't I'll never buy another gm product.

The brake line burst as I was shifting into drive could not stop vehicle, shifted it into park and was able to stop before hitting someone. Why are these lines not made of stainless steel? better yet why is this agency not doing anything about this? they jump all over a key switch that may cause a problem but do nothing for something as important as be able to safely stop our vehicles.

My husband, 3 year old, any myself were driving back from a doctor appointment when we had to make a sudden stop because of a driver 2 cars ahead of us that quickly applied brakes to make a quick right hand turn. The driver in front of us in turn had to apply his breaks on and when my husband applied the brakes on our 2004 Chevrolet Avalanche there were no brakes!! our 3 year old was asleep in the backseat!! we hit him of course because we could not stop (going downhill on a busy highway) we ended up having to coast up the hill in the middle of the lane because there was nowhere safe for us to pull off . There were almost several other accidents due to it being a blind spot for drivers coming over the hill both ways and we were stuck there because we had no way to stop ourselves again. So after all that we ended up needing our truck towed and the brake lines are corroded and had busted!! so not only do we have a tow bill now we are responsbile for replacing them! the estimate is $800!!! thanks gm! we will be selling this one soon! gm won't do a recall on these after all the complaints and accidents about the brake lines on here? seriously? we had no clue about any of this until today! the mechanic that is fixing ours today told us he has 2 more that have the exact same issue and have to be replaced on theirs too! I guess it takes people dying or getting seriously injured before the car manufactures have to take responsibility. And what makes it even worse is that the whole brake line replacement is available (for us to purchase) and it's only about $160!! nice to know the safety of our family, friends, and other motorists aren't worth it to them. Just 2 miles earlier we drove though a school zone!!!!! as the kids were leaving for the day! thank god they lasted that 2 extra miles and no one was seriously injured or killed.

Catastrophic brake failure when attempting to stop vehicle at 45 miles per hour. Brake peddle went to floor almost causing a major crash. GMC dealer stated brake lines totally rusted out and ruptured causing total brake failure. Dealer stated brake lines disintegrated in the technicians hands when the tech was removing old lines. I have read similar experiences from other gm owners on the internet. This is a major safety issue which if it has not thus far will result in injury and or death. I am one of the lucky ones who was able to avoid an accident. I am sure this wont be the same outcome for others.

When I got the truck home I notice dripping of brake fluid on driver side door. Further checking I discover my brake lines is rusting and cause a major leaks underneath my truck.

Driving in heavy traffic on I 95 south on the way to vacation, brakes failed when I attempted to slow down. I rear ended another vehicle. Had truck in shop for week and found several problems with lines and 2 leaks. I heard that there is a known metal defect with 2001-2004 brake lines. I can't find any recall information.

Rear brake likes blew out due to corrosion. Brake lines corrode at each point that they are fastened to the vehicle. No other major corrosion on the vehicle. Front brake lines also corroded but not yet to the point of failure. Stopping the truck was almost impossible.

Going down my driveway pushed on my brakes an it went to the floor,underneaththe truck by the drivers door the frame was very wet with brake fluid,the brake line had blown.

I had absolutely no warning that my brakes were failing. On a downward slope of road, (old route 23s) in cedar grove, as I was approaching a light with vehicles at a stop. My brakes were giving way and were not allowing me to stop completely. I kept on pumping them in hopes that the hydraulics would kick in; they did not. As I approached the stopped vehicles, I was ready to use my emergency break but the light turned green, I was able to continue with the travel & veered into the intersection's turn to pull over onto the shoulder where I used the emergency brake to stop and called aaa to be towed. My mechanic called me with the 'extensive amount of problems' that my brake lines are enduring. One is busted completed; the others are completely rusted and all need replacement. I have been without a vehicle for 4 days so far and am waiting to see what the true 'damages' are going to be as far as expense. I am happy that I didn't hit any other vehicles or injury anyone. I am disappointed that I had no warning and am now living without my truck and a huge repair bill on my wallet.

Brake line ruptured from rust. Chev dealer wanted $2600 to replace/fix 2004 chev Avalanche brake lines.

I came around a curve and there was road work going on and had to stop real quick. The brake pedal went to the floor. All the brake lines were rotted. I had to change every brake line on my truck.

When backing out my driveway I stepped on the brake and pedal went to the floor leaving brake fluid all over driveway. Group of brake lines along side of frame were totally rusted into a glob of rust.

I was approaching a stop sign on a residential street, pushed the brake pedal and lost braking ability. The pedal traveled to the floor, when that happened the service light came on with an audible alarm. I was able to get the truck stopped on the side of the road. A large amount of smoke was coming out underneath the hood from the spraying brake fluid. Upon inspection it was determined that there was a hole in the right front brake line. Further inspection revealed all brake lines to be in similar condition with a potential failure imminent. All brake lines need to be replaced and will cost over $1,000. The truck is not used excessively and has low mileage.

Hi have a 2004 Chevrolet Avalanche and have had nothing but problems with brake lines, transmission and the body is completly rotting out really pathetic as this vehicle was so expensive and wondering if there are any recalls as there should be?.

While driving in town locally, the braking system failed while trying to stop at a traffic light. I was able to eventually stop the truck by applying extreme pressure on the brake pedal. I pulled the truck over safely & noticed brake fluid on the ground under the driver's door. I had the truck towed to a local mechanic who inspected the braking system. All of the brake lines under the driver's door were severely rusted along with the one line that had failed.

Started my Chevrolet, started backing up down an incline of my driveway, "service brakes" indicator illuminated. Brake pedal sank to the floor. No brakes. Opened hood and the front left wheel brake line (cheap steel) was shooting brake fluid everywhere and all over the engine. It's going to a Chevrolet dealership tomorrow for repairs.

Brake lines corroded to the point of failure causing a loss of braking at 35 miles per hour. Dealer will replace entire trucks brake lines extensive repair. Personally know a friend with a 2002 Chevrolet that had the same problem. The repair center he repaired his truck at informed him that they replaced four other Chevrolet trucks brake lines in the last six months. I have been driving for forty years and never replaced brake lines on a car some with over 150,000 miles on them.

Put on brakes to avoid car slowing in front of me. Brake pedal went to the floor and had almost no brakes. Had to swerve drastically to avoid hitting the other car. Mechanic checked the truck the next day and found corroded brake lines had failed.

Turning the corner without any notice, the brake line apparently broke and the brake pedal went to the floor. Brake fluid went everywhere- was able to pull over and use the emergency brake to stop, but god forbid if I was on a freeway or was pulling my boat! could have been catastrophic! upon further investigations, all of the brakelines showing under the driverside wheel well are corroded badly and will need replaced. I have owned alot of cars/trucks and never had to replace a brake line. The costs I have been quoted are upward of 1500. 00 to repair due to the poor design and that the parts have to be ordered specifically for this vehicle. This should not be happening on a 2004 vehicle with the low miles it has.

Rear metal brake line burst while maneuvering in parking lot, losing rear service brakes. Brake fluid was gushing from burst line onto ground. A quick examination revealed burst brake line is completely rusted. Vehicle passed state inspection and 27 point safety inspection performed by gm dealer this past July. During the first week of August, I towed my son's disabled vehicle back from central PA. (140 miles). With the tow dolly and his car - I was pulling close to 4000 pounds. Can you imagine if this line burst on interstate 80 at 55 mph? when does this horror end? this vehicle has previously encountered sudden and unexpected brake failure due to metal brake lines rusting to the point of sudden failure.

While moving the truck around in the driveway we noticed fluid on the ground. Upon further investigation we noticed inside the drivers wheel well that some lines had fluid on them. I brought the vehicle to the dealer and they said the brake lines had rusted out. Luckily we had not had an accident. I had to have two of the lines replaced. This was not covered by the extended warranty because lines of any kind are not covered.
