Tl* the contact owns a 2004 chevrolet silverado 1500. while the gear was in reverse with the brake pedal depressed to the floorboard, the vehicle continued to move backwards. the contact had to apply the emergency brake to stop the vehicle. the contact heard an abnormal noise, but was able to drive home. the vehicle was taken to an independent mechanic who diagnosed that the brake line needed to be repaired. the contact stated that the vehicle was currently being repaired. the dealer and manufacturer were not notified. the failure mileage was 115,000.

Brake line failure due to rust and use of inferior parts from chevrolet. vehicle was in motion an accident was avoided due to awareness of other drivers. in a neigborhood street, with children present very near.

I know my truck is 14 years old. but my brake lines rust out near the abs block and near the fuel tank on the frame of the truck. which is odd to happen at the same time. i have heard of people having problems with this truck line sooner then me. now i have a 85 trans am made by gm and haven't had this problem . i think the nhtsa and gm need to look at this closer. this happen to me this morning on my way out to work and it scared the hell out me lucky i was just in my drive way. i take very good care of my truck and don't abuse it. i try to keep up on the under body and frame after snow storms by rinsing off the under body and frame. now i was informed i will cost me any were from $1500.00 to$ 2000.00 to repair this problem. not a happy camper. just glade i wasn't on the road doing 50. as i take local and state high ways to work.

While driving at highway speed, traffic mounted up and cars vigorously applied braked. braked truck, which slowed at first, then pedal sank to floor and ceased to stop. emergency brake deployment performed remaining necessary stopping (just barely). inspection found badly rusted brake line ruptured near the passenger rear tire, as the metal line meets rubber. all lines badly rusted while little other underchassis shows any rust at all.

Yesterday my brake pedal went to the floor and i could not stop the truck. i put my blinkers on and drove about two miles an hour to my regular mechanic and he said all the brake lines need to be replaced because the are rusted out and leaking fluid to a cost of $750.00. it is in the shop right now so i won't have the invoice for a few days. he also said the the fuel lines look rusted also and hopes they won't break while fixing the brake lines.

tl* the contact owns a 2004 chevrolet silverado 1500. the contact stated that while driving about 15 mph, another vehicle cut in front, caused the contact to apply the brake pedal forcefully and punctured the brake line. the contact slowly drove the vehicle to his residence. the dealer was not contacted. the manufacturer was not made aware of the failure. the vin was not provided. the vehicle was not repaired. the failure mileage was 21,000.

Upon exiting highway at 75 mph, i applied brakes to slow down. the brakes felt spongy then went to the floor. tried to pump with no results. this was a single lane exit ramp with a car turning left and one turning right at the end of the ramp. still at approx. 60 mph i had nowhere to go. down shift to 2nd and apply parking brake. finally one car turns and i blast through intersection about 40-45mph and just missed t-boning another vehicle. as i went down the entrance ramp back onto hwy. i was able to bring truck to a stop. later inspection of truck showed all 4 brake lines from abs to front of truck severely rusted with one ruptured. rear brake line also rusted. g.m. need to recall these vehicles before someone gets killed. at the speed i was traveling i had seconds to make a decision. i was lucky the car in front of me turned and i missed the car on the crossroad. this truck has 85,xxx miles and has only been driven in snow or bad weather maybe a half dozen times during its life so corrosion should hot have been an issue. i've owned many cars with 200,000 plus miles and never had brake line issues. i believe with as many complaints as i read about this problem you need to force a recall before someone gets disabled for the rest of there life, or someone loses a family member!!!

Tl* the contact owns a 2004 chevrolet silverado 1500. while driving 70 mph, the battery indicator illuminated. the contact attempted to pull the vehicle over when he observed that the steering wheel had seized and took great effort to turn. also, the brakes failed when the brake pedal was depressed. the contact was able to stop using the fifth wheel camping trailer that was hitched with electronic brakes to slow and eventually stop the vehicle. the vehicle was towed to an unknown dealer where it was diagnosed that the serpentine belt and idler pulley failed and needed to be replaced. the vehicle was repaired. the manufacturer was not contacted or made aware of the failure. the failure mileage was approximately 151,041.

The brake lines on my 2004 chevrolet silverado are badly corroded and one of them has failed. when this happened, the pedal went to the floor and the truck had no brakes whatsoever. fortunately i was not involved in an accident. i live in kentucky and i have had this truck since new. we receive a minimal amount of bad winter weather here so i find it hard to believe that this was caused by salt. this truck is only 13 years old.

Brakes failed on highway due to rusted lines. brakes completely failed. brake line was so rusted it had a huge hole in it due to the rust.

When braking at slow speeds between 5-10 mph the abs activates preventing safe stopping.

Rear brake line busted on 2004 chevy silverado while driving in a parking lot. really dangerous! had to hit the curb to stop! there should be a recall on these steel brake lines! in the shop now to replace all the brake lines that are faulty! a cost that should be paid by gm not the consumer of a faulty product! *tr

The abs kicks in at speeds under 5 mph on drive pavement

While towing a boat rear brake line burst losing brakes thank god i had room to hit e brake and pull to the side of the road on a back road

2004 chevrolet silverado experienced complete brake failure. driving down a short hill, brake pedal pushed completely to floor with no brake response or stopping availability. driving @ approximately 20 mph, applying the emergency brake had little effect and had to turn into a dirt hill to stop the truck. upon further inspection, 4 brake lines directly underneath the cab on the drivers side were completely corroded with 2 lines failing simultaneously releasing brake fluid onto the ground. the 2 lines from the proportioning valve in the engine compartment to the abs and the 2 lines from the abs to the 2 front wheels run parallel under the cab and are severely corroded in 2 places only. the 4 lines were severely rusted at the point of the plastic clips that secure the lines to the frame of the truck. the plastic clips that hold the brake lines hold moisture and salt and cause all the brake lines to corrode at those points. it's important to note that there is no rust in the lines to the rear of the truck or at both rear brake calipers. this is not normal wear or lack of maintenance. i clean the underside of my vehicle every winter. the lines are rusting as a result of the clips retaining salt and corrosives and causing year round contact to the brake lines. is anyone reading or investigating here? there are literally hundreds of complaints here regarding this exact issue. i have seen multiple post that list the corrosion in the exact same spot as my truck. these lines rust not from normal wear but because of a defective clip design. repair estimate from chevrolet dealer is $1250 to replace all lines. when will gm consider this a defect or write a service bulletin? *tr

When parking in my driveway, my brake pedal went to floor and i was barely able to stop. my brake lines were leaking fluid due to severe corrosion and must be replaced for over $3000.00. fortunately this did not occur while i was driving on the street.

Tl* the contact owns a 2004 chevrolet silverado 1500. while driving 35 mph, the brake pedal was depressed but hesitated to respond before the vehicle completely stopped. the service brake system warning indicator illuminated and the service brake system error message displayed across the message board. the vehicle was taken to an independent mechanic where it was diagnosed that the brake lines were corroded and needed to be replaced. the vehicle was not repaired. the manufacturer was not notified of the failure. the failure mileage was 67,340.

Steel brake lines are prone to corrosion. replaced 2 original brake lines in the last 24 months. 1st failure the brake line suddenly burst while applying the brake. second incident the brake line slowly leaked. upon inspection the lines are severely rusted.

Total brake failure. rusted brake lines. why are these not recalled? how many people must be killed or injured?

Brakes failed completely while driving on street near home. line from proportioning valve to abs unit has pin holes, i had to replace all under chassis brake lines last year, but lines in the engine compartment really? the plastic securing clips act as a container for moisture and rot the line.

Tl* the contact owns a 2004 chevrolet silverado 1500. while driving approximately 8 mph and depressing the brake pedal, the anti-lock brakes engaged and made an abnormal noise without warning. the vehicle was not diagnosed nor repaired. the manufacturer was not made aware of the failure. the failure mileage was 89,000. updated 10/07/16*lj *tr

While driving to the gym with my 2 sons with me, i luckily stopped at the dumpster in my condo community to drop off some trash. while attempting to stop when approaching the dumpster i lost about 90% of my brake pedal travel and noticed a huge mist of fluid by my drivers side door. luckily i was able to stop and then return to my parking spot in front of my condo without incident. upon parking my truck in the parking spot the remaining brake fluid emptied out. when i looked for the cause i quickly discovered that my brake lines were so badly corroded they looked like they came from the sunken titanic. i have lived in 2 states that get snow in the winter but after every snowfall i've taken the truck to the local car wash and used the underbody wash feature. i've driven 1987, 1988, and 1994 vehicles in snow states and had no brake line issues so my 2004 vehicle i'd expect no issues either. this is a huge safety risk, nowhere in the owners manual does it warn you to check your metal brake lines for corrosion. filters, pads, fluids etc are routine maintenance that the owners manual includes but metal brake lines are not and shouldn't be, not when aftermarket corrosion proof brake line kits cost $100. luckily my family or no one else's family were hurt in my incident but the longer gm refuses to recall these brake lines others might not be as lucky.

Tl* the contact owns a 2004 chevrolet silverado 1500. the contact stated that while driving and depressing the brake pedal, the brakes failed to respond. the brake warning indicator illuminated. the vehicle was taken to an independent mechanic where it was diagnosed that the brake lines had experienced severe corrosion and needed to be replaced. the vehicle was repaired. the manufacturer was notified of the failure. the failure mileage was approximately 65,000. updated 09/08/16*lj updated 06/18/18*jb

I was driving today with my lawn tractor loaded on the truck of the bed. i came upon traffic stopped at a red light. as i pressed my brakes to stop , the brake pedal went to the floor and i almost struck the vehicle in front of me. luckily i was not travelling at high speeds and the vehicle managed to move and avoid being rear ended by me after i began honking my horn as a warning. upon inspecting the vehicle, i discovered that a brake line had ruptured, which caused this problem.

Bad rusted brake lines about to fail. i see on line that gm use bad steel lines.

Pouring rain i was taking my mother to see my dad at the hospital. i started down the street and went to stop. pedal sunk to the floor. i came to a stop part way into the intersection. thank god, for god and my guardian angel that i wasn't on the highway when this happened. we had it towed to the dealership and it was corroded brake lines. it's a 2004 with 80,000 miles on it. never been off-road. why hasn't gm and the traffic safety committee issued a recall. had this been the night before coming home from the hospital we would be at a funeral. it was fortunate we were doing maybe 10mph.

Brake system completely failed while in motion. further inspection revealed the brake tube leading to rear axle had ruptured. the tube was severely corroded.

Driving late at night, all of a sudden with no warning a complete loss of brakes and all fluid. brake lines rusted and broke.. was able to gear down to slow and use parking brake thanks to no traffic late night. this is not normal as the lines are not visable without crawling under vechicle where they are up in the frame. only had 41,000 miles on truck. the cost for repair was $600.00 which i believe should be borne by chevrolet. if this had happened in traffic, it would definitely would have caused an accident. they are not located in a place where they can be seen easily.

Tl* the contact owns a 2004 chevrolet silverado 1500. the contact stated that while driving at 55 mph, the brake pedal was depressed to the floorboard but the vehicle failed to stop. the contact then depressed the emergency brake in order to stop the vehicle and avoid crashing. the vehicle was taken to an independent mechanic where it was diagnosed that the brake line needed to be replaced. the vehicle was repaired. the manufacturer was not notified of the failure. the failure mileage was 51,000. the vin was not available.

Came up to a stop sign going about 30mph.brake pedal went all the way to the floor.had to use the parking brake to stop the truck. mechanic says i need to have all the brake lines replaced. all the lines were rusted to the point one failed. the hydraulic system on this truck is not divided, meaning a hole in any line you loose all breaks. truck only has 57000 miles on it? i can't believe a recall has not been issued for this known problem. when someone dies i hope to be called to testify against gm.

Tl* the contact owns a 2004 chevrolet silverado 1500. while the vehicle was hauling a trailer, the brake pedal lost pressure and stuck to the floorboard when it was depressed. the contact was able to downshift the vehicle, coast onto the road shoulder, and apply the rear brake in order to stop the vehicle. the contact inspected the vehicle and found that the brake lines were corroded and caused the brake fluid to leak. the vehicle was not repaired. the manufacturer was not notified. the approximate failure mileage was 130,000.

Brake line failure

Brake lines rusted and ruptured. brakes failed resulting in near accident.

Rear brake line blew (along frame) pedal went to floor no brakes, i was lucky i was off road at the time of brake failure. truck has 21685 miles. brake lines should last the life of the truck. i should of only lost the back brakes, i think they may have a problem in the abs unit (echu)? they know they have a problem with these brake lines, why no recall? this will cost around $1500+ if i let them do the work.

I had just got of the interstate going about 65. after pulling in my driveway, the brakes went completely out. nothing. apon inspection, i found a rusted out brake line on the left front. this truck has never been abused as i am almost 70 yrs. old. all the lines are flaking with rust and now i will not feel safe driving it until all the lines have been replaced at a very high cost since gm does not make a replacement part. i bought this truck new in good faith thinking it would be my last. it seems to me gm should at least stand good on defective parts. now i find out this same problem has been happening all over. this is not just a few trucks either.

Tl* the contact owns a 2004 chevrolet silverado 1500. while driving 55 mph, the brake pedal was difficult to depress and failed. the vehicle was towed to an independent mechanic where it was diagnosed that either the rear or front brake lines fractured and needed to be replaced. the vehicle was repaired. the manufacturer was not notified of the failure. the failure mileage was 124,000.

Brake line rusted and blew out while stopping. known problem. government motors

Was trying to stop at red light & brake went to floor with no warning & had no brakes so unable to stop. had to keep going through light & had to use emergency brake & finally managed to stop on side of road. brake fluid was all over ground under the truck. fortunately this happened only going 25 miles an hour in a suburban setting. never had a problem with brakes before.

The truck was bought new in south carolina in 2004 and has only traveled to "snow belt" states in the winter less than a dozen times in past 11 years. on 7/23/15, while on vacation, the vehicle suffered a sudden loss of all braking power. fortunately, my husband was able to get the truck stopped in time before hitting the car in front of us by shifting into neutral and pulling the parking brake. after pulling off of the road and opening the hood, we discovered that a small fire had started from the spraying brake fluid hitting the hot manifold. again, we were fortunate to get it doused in time before any major damage occurred. once we found out that the front left metal brake line had cracked, we carefully made our way to advance auto using the neutral and the parking brake to stop us when needed. my husband was able to patch the corroded brake line in the parking lot of auto at 8 pm at night only to discover the other front line was cracked as well. by this time it was too late to fix so we made a harrowing trip back to our hotel without any real brakes. good thing their wasn't much traffic and we were close to our hotel. the next day we were able to find a local repair shop to replace the right front brake line. they mentioned they had replaced one on a chevy suburban only a day earlier from indiana for the same reason. after searching the internet for this issue, i must strongly disagree with gm when they stated that the brake system on the affected vehicles is split between the front and the rear and that "should a brake pipe suddenly fail for any reason, the affected vehicle would be capable of stopping with the pressure supplied by the remaining circuit." we had no brake pressure at all and had no way of stopping. it was only my husband's quick thinking that saved our family and another family from an accident. i hope this matter will be investigated further.

On july 22, 2015 i was driving my 2004 chevy silverado 1500 and when i went to stop at an intersection the brakes failed and i had go through a stop sign. i had to hit the emergency brake to get the truck stopped. i was lucky it happened in a housing sub division and not on an interstate because someone could have been killed. i was close to my mechanics garage and was able to get it into the garage where i was informed that all of my brake lines were completely corroded and rusted through he also informed me that a brake caliper needed replaced due to all of the brake line corrosion. the mechanic also informed me that all the fuel lines were corroded and also needed replaced. the mechanic told me he has replaced brake lines on several silverado's all due to corrosion. this truck only has 65,665 miles on it and was seldom driven in snow. i'm not sure why there is not a recall on these trucks. if my wife or one of my kids was driving this the outcome could have been different. the total cost was over $1400.00 to get all of the lines replaced something needs to be done before someone gets killed.

Brake lines leak due to excessive corrosion. . all the lines have been replaced months ago. the truck has less than 50 thousand miles. i feel this is way to soon for this problem. the dealer laughed when i asked if this was a warranty problem.

On 7/3/15, my husband applied the brakes to stop in order to exit a restaurant parking lot. the brake pedal went to the floor we (my husband, child, and i) drove across the marked parking ways and crashed into a parking lot sign to make the vehicle come to a stop. upon exiting the truck, my husband noticed the brake line leaking. we were blessed that we had not pulled on the main street into oncoming traffic. we had to get the vehicle towed to a shop for repair. i also called don moore automotive service department and had no response. *tr

Tl* the contact owns a 2004 chevrolet silverado 1500. while driving at 30 mph, the brake system failed without warning. the vehicle was towed to the dealer. the technician diagnosed that the brake line fractured. the vehicle was repaired. the manufacturer was not made aware of the failure. the failure mileage was 76,395.

Thank god i was not traveling i got up in the morning to go to work and placed my foot on the brake in which it went to the floor which was odd i pumped the brake a time or two and heard the sound of dripping fluid under my truck i shut it off and looked under my truck to see a stream of brake fluid down to the ground. i could have only imagined what would have happened if i was on my way to work and this had happen or if i had my family with me on the way to the beach. this could have bee catastrophic not only to me but to my family and everyone on the road. i am an aircraft mechanic and after reading some of these known issues and chevrolets response to them my question is how can you continue to admit there is not a problem. i mean there are some things i can see needing regular maintenance on a vehicle and brake lines that are made out of steel is not one of them. the airlines use stainless steel in the aircraft to help resist corrosion for this very reason. why put peoples lives in danger when you can fix it with better quality parts.

Brake pedal would constantly go to the floor after stopping at light, etc. within a day brakes went to floor without stopping vehicle. added two pints of fluid which immediately leaked out. repair facility said they had to replace driver side rear brake line.

Complete loss of braking ability without warning and fluid leakage due to corroded brake lines. fortunately the incident occurred while parked at home, but necessitated towing the vehicle to the dealership and a costly repair.

I was leaving the house with my boat hooked up and got on the highway, we had gone for a half mile and the brakes went to the floor and found out the line was rusted. then the second time it happened again and i was told that most of the lines were badly rusted and had to replace them all. it is a shame that the lines are faulty and could kill many others this is a serious problem in any vehicle-don't you think so!
