Recently reported SERVICE BRAKES problems on 2003 Chevrolet Silverado 1500

I was driving my 2003 chevy silverado down the road and when i went to slow down my brake pedal went to the floor after getting pulled over into a parking lot i inspected the lines and saw that they all had busted and were all very rusty i took it to the mechanic and he stated it wasn't worth fixing due to the excessive rust on the frame and gas lines it would cost more than the truck was worth. *tr

Went to park my truck and the brake pedal went to the floor, tried to pump the pedal but it still went to the floor. shut the truck off and looked at the under side and seen brake fluid running out of a brake line. and i looked a little closer and seen that most of the brake line under the truck were rusted very bad. had to have my truck towed to the shop to be fixed. they said that all my brake line must be replaced or i could have a bad wreck. and the price. not good. *tr

Upon leaving my house in said truck yesterday, 12/14/2014, fortunately i was still within my subdivision, i experienced total brake failure, with the pedal going all the way to the floor. the only thing that stopped the truck was a snow bank. the service brake system message displayed at the same time. there was no prior indication or warning that my brakes were getting ready to fail. i was able to get the truck back into my drive way using the emergency brake and called aaa. there was brake fluid everywhere under the truck. they towed my truck to aaa care in fredericksburg, va where they discovered the hole in the line due to rust. they replaced the line from the lf wheel to the abs pump with total repairs coming to $415. they also advised me that all the brake lines are rusting and could fail at any time. i understand the truck is 11 years old however i am the original owner and always washed and maintained vehicle including undercarriage cleaning. *tr

I was traveling down the road, was approaching a red light, applied brakes, they did not work. went through a red light, applied emergency brakes, came to a stop. immediately returned home applying emergency brake, thank god i was only around the block. upon examining the brakes under the car, all of the lines were rusted out, causing a loss of all brake fluid. i consider myself lucky, that i did not have my family with me and i did not hit another car. this is a problem, does some one have to be killed first before this is considered a recall? *tr

I applied brakes coming up to a red light. vehicle did not stop and pedal pushed to the floor. applied e-brake to stop and resumed to repair shop on other side of lights. found brake line had pin holes. *tr

Tl-the contact owns a 2003 chevrolet silverado 1500. the contact stated that the vehicle rolled away from the drive while the gear was in park position and crashed into a tree. the manufacturer advised that the vehicle was not included in nhtsa campaign number 05v161000 parking brake. the dealer advised that the parking brake failed and needed to be replaced. the vehicle was not repaired. the approximate failure and current mileage was 150,000. li

On 12/15/13 i was pulling into my driveway when i suddenly lost all brakes. i was helpless to stop the truck with my power brakes, the brake peddle went to the floor. the only way i could stop my vehicle was to use the parking brake. on 12/17/13 i took the truck to my mechanic. he informed me that two brake lines had ruptured and the others were leaking badly. this, according to the mechanic, was due to the chemicals used to treat the road surface in the winter. the chemicals had corroded each brake line to the point of catastrophic failure. at a cost of $834.21 all of my brake lines were replaced. *tr

A brake line ruptured, seriously impairing the braking. this happened on a day that ice was on the road, increasing the possibility of an accident. the brake line was replaced, and others inspected and deemed safe. on october 3, 2014, another brake line ruptured. this happened while at low speed. no accident or damage occurred. i will have this ruptured line replaced along with all other original brake lines. last gm product i will buy in my lifetime. *tr

While attempting to stop in front of a store my brake pedal went to the floor i shifted into park to avoid hitting the person in the crosswalk. my truck was towed to the dealer and i was told all brake lines were completely rusted the gm rep told me it was an old truck with many miles as a retired gm employee and a licensed mechanic i have driven many older cars and never seen this kind of rusted out brake lines . will it take a few deaths and lawsuits before owners of these trucks are warned? *tr

My wife was driving our 2003 chevrolet silverado 4x4 pickup on secondary state route. while descending an approximate 6% grade into a right hand turn at bottom she depressed the brake pedal to slow for the grade and turn and it went to the floor, the service brake message came up in the dic and the door chime sounded. she pulled over as soon as possible as she was shaken from riding out that hill and turn with minimal brakes and called me. i went out and drove the truck back to our home and put in the garage to inspect the problem. once under the truck i found brake fluid dripping from the side of the fuel tank and frame area under the cab and bed of the truck. the service brake line from the abs block to the rear frame point where the brake hose to the rear axle mounts was corroded through and leaking. further inspection showed all brake hard line plumbing to be in poor condition and also the fuel lines showing high corrosion. a call to a local gm parts counter revealed that gm does not make a replacement set for these lines and that a technician would need to field bend and make up each line. later research proved this to be wrong as gm offers a deeply discounted unadvertised line set from ac delco. in researching finding parts to repair, i have found this to be a common problem with chevrolet/gmc trucks from about 1999 up according to the various truck owner forums online. driving the vehicle home at slow speed, braking was very minimal with the rear brake circuit out,and the knowledge of poor brake operation, so therefore it is my opinion that this is a safety issue with these vehicles with the potential of injury or even death when all the factors combine poorly, and at the least, gm should be required to notify owners of this potential problem with their vehicle, if not recall and repair those effected vehicles. *tr

Tl* the contact owns a 2003 chevrolet silverado 1500. the contact stated that while driving approximately 45 mph, the brakes were engaged but the brake pedal sunk into the floorboard and failed to stop the vehicle. the contact mentioned that the service brake system warning light was illuminated. the vehicle was not taken to a dealer for diagnostic testing or repairs. the manufacturer was not notified of the failure. the approximate failure and current mileage was 68,000.

The brake pedal was depressed and the pedal went to the floor. i was able to get the truck back to my house. looking under the drivers side rear wheel, brake fluid could be seen dripping from a brake line. *tr

Pulling into my driveway the brakes went to the floor and almost hit my other car. steered around it and went into the yard. after checking my truck i found a metal brake line under the driver door rusted and leaking fluid. very lucky it happened at home i guess. *tr

I was driving my 2003 chevrolet silverado 1500 late at night when a deer entered my lane of travel. i depressed the brake pedal but nothing happened. i luckily avoided the deer by swerving. i was able to get the vehicle back to my residence by driving in first gear and using the emergency brake. when home i looked under the vehicle and noticed brake fluid leaking from one of the corroded brake lines on the outside of the frame (driver's side) where it bends to go into the abs module. further inspection revealed that the lines are completely corroded clear up along the frame and where they enter into the brake reservoir. noticing this, i am now going to have to replace all of the lines so that i don't have this happen again. these lines are a danger and should be replaced by gm. if this would have happened in traffic, especially slowing down for a light or stop sign, an accident would have most likely happened. i would recommend to anyone that is reading this to visually inspect your brake lines. a large portion of the lines can be seen by simply laying down in the area of the driver's side door to the front wheel, and looking at the frame to where they are attached. *tr

Well about mid 2012 the brake lines just rust out in the middle of the truck and the rear. my girl friend was driving it to work and lost all the pedal pressure. thank god she was going up in the parking garage. right now i'm trying to replace line fuel lines. it just started pouring gas out after i just got to work. i nursed it home and made it. the return line is just all rusted out. then i noticed all three lines where all rusted out. it's to bad nothing has been done yet i can't afford this! it is well known and understood by many that this is a big problem. also to top that the frame looks more rusted than the 1989 dodge i just got ride of. i wash under the truck through out winter and don't understand why it's so bad already. *tr

The brakes began failing as we were driving to work. my wife carefully drove the truck straight to the repair shop and barely managed to stop it. mechanic reported that several brake lines were leaking due to corrosion. that's not surprising considering everything underneath the chassis is corroding rapidly. most corrosion prone vehicle i've owned in 25 years. this vehicle should have been recalled for corrosion and electrical problems which i'm constantly dealing with. *tr

Brake lines rusted out. had to drive 60 miles and chose early morning due to having almost braking power. we have a ford truck of the same year and the brake lines are still very good. there is no excuse for this other than a good company going on the cheap. !!!! *tr

Tl* the contact owns a 2003 chevrolet silverado 1500. the contact stated that while driving 5 mph, he attempted to engage the brakes but the brake pedal sunk abnormally into the floorboard. the contact then attempted to engage the emergency brake but it also failed. the vehicle was taken to the dealer where the technician diagnosed that the brake lines were completely corroded. as a result, the brake lines and the calipers would need replacing. the manufacturer was made aware of the failure. the vehicle was repaired. the failure and current mileage was 47,305. updated 12/20/13*cn

Was pulling into a parking lot towing a trailer when the brake pedal went to the floor. i was able to avoid other vehicles and go in circles till vehicle finally was able to be stopped. i had no brakes at all and upon inspection found that a brake line had ruptured. i also noticed that all the brake lines under the vehicle were extremely corroded. this would have been drastic had it happened on the road at a stop light or intersection, i or someone else would certainly had been killed or seriously injured. i understand that nhtsa and chevy are aware of the brake line rusting out problem with these trucks and refuse to do anything about it ? *tr

As i was driving and using the brakes i noticed that the brake pedal was going further and further to the floor. when i got home i noticed that fluid was leaking from the rear of the vehicle. the leak was from a rear brake line that had completely rusted through. i looked at the other brake lines and noticed that they were all severely corroded. took the truck to chevrolet dealership and was told that all the brake lines needed to be replaced due to the corrosion. they were concerned that the other brake lines could leak at any time. i had the lines replaced at the dealership at a cost of $2600.00. this is a very serious defect that could have been catastrophic. *tr

Was making a 3-point turn on a local residential street, and suddenly, my brake pedal went to the floor. slowed the truck down enough to avoid hitting anything. vehicle was towed to repair shop, and needed a rusted-out brake line replaced. i was also advised that all the brake lines were extremely rusty, and needed to be replaced asap. *tr

This is the second brake line that has failed on my 2003 silverado 1500. this time my 8month pregnant wife was driving. she nearly drove right through a red light at a busy intersection. there is no warning when these lines blow brake pedal goes to floor and doesn't even slow you down! luckily she thought fast and kicked down the emergency brake. when is something going to get done about this problem. how many close calls and or deaths need to happen before something gets done ? *tr

Tried to use my brakes to exit the highway. pedal went straight to the floor. pulled over to find my brake line rusted out and leaking. *tr

While driving 35-40 mph, depressed brake pedal to slow at a traffic light. brake pedal went to the floor with no warning sounds or lights. made it home with no further issues. the next morning a puddle of brake fluid was discovered on the driveway. (driver side rear) after further investigation, a large leak cause by corrosion on a brake line connection was discovered. all brakes lines are severely corroded. this could have been a serious accident and caused loss of life or serious injury. suspect material defect. request a gm recall to replace defected parts/materials. *tr

Got in truck to return home, pressed brake pedal,pedal went to floor. absolutely no brakes at all. luckily wasn't going but 5 mph. had truck towed to dealer next day. was informed by dealer that brake lines were completely rusted out, cost of replacement to be 900.00. truck has only 53000 miles. have had 15 to 20 cars in my life and never had this problem with brake lines on any other cars or trucks. gm should be ashamed to put out this kind of product. very, very disappointed.

Traveling down busy four lane boulevard at 55 mph in heavy traffic. traffic slowed in front of me, brakes went to floor, pumping brakes failed to slow the vehicle. had to cross four lanes of oncoming traffic to avoid rear end collision. was able to slow vehicle by putting in a lower gear and then rolled to a stop in about 200 yards down a service road. mobile mechanic stated all brake lines are severely rusted and one of the rusted brake lines blew out. lucky to have avoided death or injury. *tr

On 09/10/13, 1:45 pm, i was driving east on s.r. 73 near i-75 intersection. as i approached the intersection traveling approximately 35 mph, the light changed to yellow. i braked somewhat hard and the brake pedal went to the floor board. there was no braking control at all and i proceeded through the red signal. approximately 500 feet after going through the intersection i managed to stop in the median. fortunately, although traffic was heavy, no contact occurred. immediate inspection revealed a brake line rusted through. i trailered the truck to a chevrolet dealer who found not only "all" the brake lines were dangerously rusted, but the gas lines also were dangerously rusted. the dealer stated this was a common occurrence with chevrolet silverado. replacement of these items required removing the truck bed which revealed the brake rotor backing plates rusted "away." severe frame and component rust was also found. only repaired brake and gas lines. cost, $1,765.11 oh, by the way, the "service brake system" warning light came on after brake failure.

Noticed that brakes were "spongy" the night before. in the morning i started the car, and started to drive out the driveway when i applied the brakes , the pedal went to the floor. the dash board information center indicated "service brakes". i got out and lifted the hood to detect the issue. i saw fluid leaking from a rusted brake line. upon closer inspection i noted that it ruptured. the real issue is that this could have happened while in traffic or when exiting my driveway which is 100 feet elevation from the road. either way it could have been a very dangerous situation. after this happened i researched similar incidences with the silverado. this seems to be a design default that should have a safety recall. i have owned many vehicles, some years older than this 2003 and this is the first time a brake line ruptured. *jb

when slowing down to make left turn, i had to stop to let traffic clear. stepped on the brakes the peddle went to the floor. drove in low gear with boat in tow to nearest parking lot. checked tosee what was wrong. found a hole brake line, line all rusted.

I stepped on the brakes. made a complete stop. the brake pedal then went to the floor, the warning display stated service brakes. when i looked under my truck, all my brake lines were seriously bubbling with rust and one of the lines ruptured. i plan on replacing them with aftermarket stainless lines. i feel this is a serious problem and may cost lives in the future. please make gm recall and repair these brake lines! *js

Total brake failure as a result of corroded and rusted brake lines on a ten year old silverado that has been well maintained and taken through car washes including undercarriage washes at least six times a year here in new jersey. as i slowed for a light the brake pedal traveled further than normal and as i the pressed the pedal it went to the floor. only quick reflexes and jumping a curb into a empty parking lot prevented an accident, the check brake service light was now on. i checked the brake fluid and not a drop remained. i broke down near a brake repair business and got the truck to them the next day. one week later 36 feet of new stainless steel brake line was added at a cost of $1113.87. i retained the old rusted out lines in case needed down the road. apparently no sensor to indicate brake fluid was low. research after incident reveals this to be a common problem with that model year. at the very least warnings should have been issued on these defective brake lines. *tr

My dog and i hopped into my 2003 silverado ss to visit my mother who lives only about 15 minutes away. as i was approaching a stop light "a busy route" that was turning yellow and i went to apply the brakes and it went to the floor! luckily we had enough time to make it through. my mothers house is just on the other side and i used the e brake to make it into her driveway! i got out crawled under the truck to see the main hard brake line was severely rusted and found it leaking. i thought to my self [xxx] what if i 20 seconds later? what if the light was already red? my dog myself and my beloved truck could have all been in a horrible accident and could of also injured another innocent driver! so i decided to google it to find that there is [xxx] ton of other people who have the same issue and that there is no recall what a load of bs!!! and this is what brought me to here. a truck down and a very unhappy camper. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

Brakes failed coming home from a routine errand. applied brakes and brakes failed due to rusted brake lines. lost brake fluid and use of front brakes. advised by automotive repair shop all brake lines rusted and need to be replaced. truck is well maintained and serviced quarterly for oil and/or fluid changes. truck also serviced annually for a check up. no issues reported by dealer (07/2012). from doing my own research there have been an overwhelming amount of complaints regarding the failure of these brake lines in gm trucks built from 2000-2003. *tr

Backing out of my driveway, my brake pedal wheat to the floor and stopped slower than usual. i opened the hood and found the front left brake line had burst. all the other bake lines are in terrible rusty condition. *tr

My wife and newborn child were in the truck, when all of the sudden the brakes stopped working. further inspection indicates that the metal brake line rusted through and burst. luckily they were turning and going around 10 mph or this could have been catastrophic. *tr

On august 7, 2013, i was heading into richmond, ky and was approaching a stop light. i began to lightly apply pressure on the brake and began to slow down. as i continued to apply more pressure, the brake pedal went to the floor and i had no brake pressure. i had no warning lights or messages on the dash board at this time. i continued to pump the brakes in an attempt to regain brake pressure but was not successful. while still pressing the brake pedal near the floor, i noticed the vehicle was beginning to slow down, but not enough to stop at the light. fortunately no one was in front of me or at the intersection as i approached it. i used the upcoming hill to continue to slow down and eventually made it to a vacant parking lot. once i came to a stop the vehicle dash board lights appeared about the brake system issues. after contacting the local gm service station, i was able to put the vehicle in 1st gear and slowly make my way to the service location on side access roads. the dealership determined that all the brake lines were rusted and several had failed. this caused the brake failure and they all needed replaced. the repair cost was over $2300. my truck had 185,591 miles at the time of the incident. i had recently moved to ky but was living in ohio for most of the ownership of the truck. *tr

i had just got work and started to drive home, when i approached the first stop light my brake pedal went to the floor. i was able to stop my truck in time because i was driving at a low rate of speed and there were no cars in front of me. i pull off the road into a nearby parking lot and got out to see if there was fluid anywhere around the truck. it was leaking from under the truck near the driver door. i got down to look under it and noticed 4 long brake lines next to the frame that were rusted very badly. i didn't take notice to witch was leaking due to the amount of corrosion on them. i then began to look at all the lines and they all appeared to be rusted very badly. i had the truck towed and have not yet had it fixed. im pricing out complete kits and do have the money to get it yet. i hope that gm can come up with a resolution so that other owners do not have accidents or fatalities do to this ongoing problem.

While driving home from work brake pedal went to the floor after left rear brake line failed. brake line fail do to rust. truck's stopping distance had increased significantly and i was lucky wasn't in traffic. no accident occur, timing was a factor for that. outcome would have been different if i was towing my boat and in traffic. note: i have been driving chevrolet trucks for over 39 years, and never had brake line fail, especially for rusting. truck's left rear brake line was replaced by goodyear barry road tire & service, cost of $181.20. *tr

To prepare for a routine oil change, i was looking over engine compartment when i notice severely rusted brake lines. at the repair facility we put car on rack and saw significant (90%) rusted brake lines. i am having all brake lines replaced to know i am operating a vehicle that i will stop when i need it to. i see no viable alternative action. i've been driving 20 years with suburbans and never have seen such poor quality material for an important system. *tr

Driving south on garden state parkway new jersey, stopped to get nj numbers, truck stopped fine. upon getting back into truck placed in reverse stepped on brake, right to the floor, no warning, no lights, nothing. went back into store bought some brake fluid filled reservoir pumped brakes back up and did get some pedal. upon starting truck applied brakes, right to the floor. checked under truck, fluid leaking from rear, appeared to be from above the pumpkin. upon having the truck towed home approx 30 miles, next day checked under vehicle, brake line rusted right through, leaking all of extra fluid out onto pumpkin. i do believe if i had been traveling north on the parkway at speeds of 65mph and had to hit the brakes in any emergency situation, the aftermath could have been fatal for someone. i have been driving for 50 years and have never had a brake line rust through and pop with out any warning, very dangerous problem. the brake lines are majorily flawed, such a high pressure system should be stainless steel, not some cheap steel that could have proven fatal. thank u for listening. *tr

Tl* the contact owns a 2003 chevrolet silverado 1500. the contact stated that while depressing the brake pedal to stop the vehicle, the brakes failed increasing the stopping distance of the vehicle. the vehicle was taken to an independent mechanic, who diagnosed that, the front and the rear brake lines was corroded and rusted. in addition, the mechanic discovered that the emergency brake actuator was rusted and needed to be replaced. the vehicle was repaired. the manufacturer was notified of the failure. the failure mileage was 38,000.

Hit brakes as attempted to stop after turning into driveway. brakes felt soft as being applied. apply pressure to stop, pedal went to the floor. did mange to stop by shifting into reverse. after stopping large oil pool under car. both brakes lines to front ant rear brakes were rusted and had ruptured. *tr

I was in the right lane on the highway going approximately 50 mph several car lengths behind 2 cars in front of me. cars in front of me stopped suddenly. i applied the brakes but they immediately failed. swerved hard into the left lane to avoid collision. checked the brake lines and they are corroded and burst at the point of corrosion. *tr

Brake lines failed due to rusting out. brake fluid leaked out all over the ground. fortunately i was in my driveway at the time. i lost brakes without warning. *tr

In bumper to bumper traffic for aprox 4 mins and stopping and starting hit the brakes , peddle goes to floor hitting car in front of me because no brakes. after accident police officers noticed fluid coming from under truck, called for a tow truck because no brakes at all, when on tow truck{ flat bed} they saw that brakes lines that run along frame were totally rotted out and popped causing this accident. truck at the shop as we speak getting all new lines installed at the cost of 1000.00. always bought a american vehicle all my life 55yrs but when i get this back it will be for sale....never again will i buy a chevy or any other american made vehicle.....i been a union pipefitter 40 yrs 3rd generation,,,,,and will be spreading the word..................... *tr

I was driving along almost home and when applying my brake pedal it went to the floor. i still had a little stopping power so i slowly drove it on home. i found that the brake line on the left front had ruptured. i have since replaced it but all of the other brake lines look severely corroded and look like they could rupture at anytime. i haven't ever had a brake line rust and rupture before. i got online and found that there are many cases of this happening to this particular vehicle and it's not an isolated incident. this could cause a severe accident and if the timing is bad it could cause a death. i'm sure that the number of cases reported are only a fraction of the incidents. i looked at the brake lines on my 2004 freestar and they're in great condition. *tr

Total brake failure all brake lines rusted 2,000.00 repair. *tr

Tl* the contact owns a 2003 chevrolet silverado 1500. the contact stated that while decelerating, the abs erroneously activated. the contact stated that the failure was also present on dry pavement and caused an increase in stopping distance. the vehicle was not diagnosed or repaired. the manufacturer was not notified. the failure mileage was 70,000. the vin was not available.

Backed into my driveway and pressed brake to stop and pedal was suddenly extremely soft and went very far down. i had no brakes at all at this point. i had to use my emergency brake to stop while only going a few miles an hour. i was running errands earlier and had absolutely no warning brakes were about to completely fail, no audible or visual warning from instrumentation at all, and no prior soft pedal or poor stopping capability. i want gm to pay for all new brake lines for this truck now! upon inspection, all the brake lines are in an advanced state of corrosion. *tr

When attempting to stop on dry pavement at slow speeds, five miles per hour or below the anti lock braking system activates which prevents the vehicle from stopping correctly. this is a safety issue which can lead to rear end collision. they have recalled many other vehicles for this same exact problem (speed sensors and bearing assembly failures) and it is obvious my vehicle has the same exact problem and should be recalled for correction for safety reasons. *tr
