36 problems related to brake hoses, lines/piping, and fittings have been reported for the 2000 GMC Sierra. The most recently reported issues are listed below.
My pickup truck was in motion when driving on a city street I had to slow down. The brake-petal went almost completely to the floor. I almost hit the vehicle in front of me while trying to stop. After pulling to the side of street I checked under the truck and discovered that the rear metal brake line adjacent to the truck frame had rusted and burst.
Brakes failed unexpectedly. The pedal went all the way to the floor and barely slowed down the truck at all. This was due to a brake line that rusted through. The repair was $765. Had I been in an area with higher traffic there would have been an accident.
Brake line rusted thru causing the truck to lose brakes entirely. This vehicle has never been out of florida, and I am the original owner since new. Never driven on salty winter roads or snow.
My 2000 GMC Sierra 1500 pickup, which has spent its entire life in virginia, lost its brakes while I was towing a dual-axle trailer and boat. Thanks to god's protection, this happened right as my made my final stop right in front of my house, so I was barely moving. Had this happened just moments earlier, I would have been travelling around 50 mph on a winding country road. I looked under the driver's side door and found the brake line and fluid running from it. While there was surface rust on the lines, I wouldn't say it appeared that a failure was imminent. Clearly, inferior materials were used for the brake line when less corrosive materials should have been used. Gm should acknowledge their poor choice of materials and provide, at the very least, replacement brake line sets. Their current "deeply discounted" set costs more than an aftermarket set.
Truck was parked. Went to put it into drive and stepped on the brake pedal. The pedal went to the floor. The steel brake line back by the driver rear wheel ruptured. On closer inspection, I will have to replace all brake lines as they are so rusty and corroded. It is a safety issue. I was fortunate that I nor my wife was traveling on the road when this happened.
The brakes in my GMC pickup truck failed due to severly rusted steel brake lines. Two lines burst , one after the other , as I pumped the brake pedal to stop the truck. An inspection revealed extensive and premature rust throughout the brake line system, requiring replacement of all of the brake lines.
Brake line rusted out.
Brake line leak from rust hole in brake line below drivers side door. Almost hit the vehicle ahead of me. I have gm vehicles that are much older than this one and never had this happen before. 1977 chevy, etc. I feel a recall is in order, I have read on the internet about other people having the same problem that didn't end as well I did.
Travelling to work one morning on a busy, well traveled road I was approaching a traffic light. I was driving approximately 40 mph. There was a few cars ahead of me and we all had to stop for the red light. As I applied the brake and started to slow down suddenly the brake pedal when to the floor and I realized I had lost the brakes. Realizing that I was going to rear end the cars in front of me I was forced to shift to 1st gear on the automatic transmission and swerve to the right off the side of the road. I came close to hitting some huge trees and running into a ditch. After my nerves settled down I safely pulled out of the embankment and slowly drove the truck to a safe opening very close by. I started troubleshooting my brakes and found a leak under the truck behind the front drivers side tire. I looked closer and found that one of my brake lines had burst open. Looking at the brake lines revealed they were all rusted badly. I had my truck towed home. As we were driving home the tow truck driver told me that these trucks have a strong history of rust problems of the brake lines and other areas. After unloading the truck I went online and started reading about the rust problems on these vehicles. I was shocked at the amount of people having the same problems. I cannot understand why there has not been a recall on an issue so important as brake lines rusting out. I am wondering if someone has to get killed before something is done about it. I encourage anyone who owns a 1999-2000 GMC or chevy pick up truck to check your brake lines and if they are rusting (which almost all are) to file a complaint with the NHTSA. Dot. Gov/vehiclecomplaint.
Repeated brake failures due to corroded brake lines.
After putting the vehicle into reverse I went to stop and the brake pedal went all the way to the floor indicating a loss in brake fluid pressure. I looked under the truck to investigate the matter and found brake fluid everywhere and a highly corroded brake line just to the rear of the abs hyrdraulic unit. It was evident that was the spot of the line failure due to the high amount of brake fluid that had been shot out of the line above it. Upon inspection I have found that the other brake lines are also highly corroded.
Driving truck in town applied brakes at a stoplight brake pedal went straight to the floor. No brakes at all had to go thru the red light and around 3 cars in front of me, rubbed the curb to get the truck to stop. Rust and corrosion on the steel rear brake lines caused line failure.
Brake lines rusted thru and had complete brake lost. The rusted lines are at the anti-lock part that controls the anti-lock brakes next to the frame. I have had this truck since it was new and keep it in great shape.
Brake lines rusted out.
I was going to go to the store with my truck and stepped on the brake pedal and it went to the floor. I looked under the door and the brake fluid was running onto the driveway and the brake line was all rusty and failed. I was going to be driving on the highway at 65 mph and con only imagine what would have happened.
I own a 2000 GMC Sierra 2500 4wd. I bought this truck new in June of 2000. In the past year, the corrosion issues are becoming overwhelming. Yesterday, a brake line blew out while driving. The brake pedal went to the floor as I approached a stop sign at an intersection with a state highway. Luckily, I got stopped as I was only going 25 mph. I babied it to a local garage 1/4 mile away, and found brake fluid dripping out below the fuel tank area. After looking underneath, the mechanic noticed that most of the brake lines will need replaced because of rust. Goes along with the corrosion issue under the whole truck. I've already replaced the rear spring shackles on both sides, as one had rusted and broke in half while driving. This caused the leaf spring to slam up against underside of the bed, which dented and cracked the paint in the bed. I restore vehicles for a living, and I've seen cars from the 1940's that don't have this much rust on the underside. Come on gm!! it's great that the body looks like new and the engine runs great, but it doesn't do any good when the frame rots out from underneath!! and now the brake lines---glad I wasn't going 60 mph with a loaded trailer when it blew!!.
The contact owns a 2000 GMC Sierra. While driving approximately 15 mph, the brakes were engaged to make a turn and the brake pedal extended to the floorboard abnormally. The contact was able to stop the vehicle after applying the brake pedal repeatedly. The vehicle was taken to an authorized dealer who advised the contact that the front brake lines were corroded. The vehicle was repaired. The manufacturer had not been notified of the problem. The approximate failure mileage was 103,000. . . . . Updated 08-24-12 the consumer stated the rear brake lines were corroded as well. On 08/10/2012 the vehicle's brake lines broke again. Updated 09/04/2012.
While positioning my GMC Sierra pickup to backup my utility trailer the brakes completely failed. The brake pedal fell completely to the floor with no stopping capability. Brake fluid was found squirting out of a burst open metal brake line located on a frame member under the area of the radiator. I traced the line from the front right wheel to the brake control module located under the drivers seat. The location of the leak was in a straight section of the line with no clamps in the vicinity. All the brake lines appear to be completely rusted. The truck is now obviously undrivable. I had just finished a 20 mile road trip and arrived home when the brakes failed. I was always under the impression that the brake system was completely separated, front from the rear. I don't understand how one burst front brake line can cause complete brake failure. I am looking for direction.
Rusty, corroded brake lines has caused two brake failures.
Corroded hydraulic brake line resulted in substantially reduced braking. This failure occurred during a stop which required higher pedal pressure than typical application, causing the corroded line to burst.
The frame on the truck is cracked several inches in a couple of places and rotted. It is very thin and I was told there was nothing solid to weld to and repair it. They said I would have to have the frame replaced. The truck has just turned 100000 miles. I have had it for six years and take excellent care of it. It runs great. The body is in excellent shape, there is one small hole in the driver side rocker panel I was going to repair in the near future ( I do not know if I will now bother). Other than that the body is near perfect. There is no rot in the floors or truck bed. The repair shop could not believe how bad the frame is when the truck looks so great. I have found a number of complaints on the internet similar to this, maybe if enough people speak up something will get done. Also, the anti lock brakes have not worked for some time now. I was told they get rust in the assembly and do not work right. I have also had several brake lines break and need to be replaced. I realize that brake lines do rust over time and do need to be replaced (they should be made from stainless steel from the factory) but the anti locks should work and a frame should not rot and crack as it has.
Nhtsa should be opening investagations concerning the brake line corrosion incidents. We just purchased this truck less than a year ago, and brake failure caused us to have this in the shop for over a month and still have no truck yet. There are enough complaints on the internet for the NHTSA to have a recall before someone gets killed due to this problem. This truck only cost us 6000. 00. Repairs will probally be half that price.
Several brake lines have rusted through, this caused loss of brake fluid and loss of any braking. This has caused me to be without a truck. Do to this defect GMC has caused a very dangerous vehicle to be on the road. This will now cost me two thousand dollars to make my truck safe to drive. GMC needs to be held responsible for this poor material in brake line material. Please correct this defect before lives are lost.
On 9 June 2011, I was towing my 8,000 lb camper back from the dealer when I pushed on the brake pedal and it went all the way to the floor, I used my camper brakes to stop the truck and find out what was wrong. I had to travel about 30 miles without brakes pulling my camper using only the camper brakes with the brake controller inside the trcuk. Once I arrived home I found a line of fluid on the ground, I opened the hood and found no brake fluid in the resevior. I refilled the resevior and had my wife push the brake pedal so I could find the leak. The brake line under the drivers door going to the front right tire was leaking. This happened about two years ago with the left rear brake line, I at that time was also pulling my camper. Thank god there was not an accident involved in both, I consider myself a very good driver and a safe driver. All my brake lines need replaced on my 2000 GMC seirre truck. I have never seen brake lines rust and corrode like this, this is not good for gm. I take good care of my vehicles and this is something that will cost me alot of money to replace these lines. You look at my truck and can see that I take care of it, it does not look like it is a 2000 from the outside, but look at it from underneath and it looks to be 100 years old. I still have the part of the line that I replaced this past week, but the line I had to replace 2 years ago I do not have.
Backing vehicle out of driveway, applied brake and pedal dropped to floorboard with loss of braking ability. Found all brake lines severely rusted, with a rupture in the line from the abs module to the rear of the vehicle. All brake lines will need to be replaced.
The contact owns a 2000 GMC Sierra. The contact was braking from approximately 55 mph but the vehicle would not respond. The contact downshifted from second gear into first gear until the vehicle rolled to a stop. The vehicle was towed to her insurance companys repair facility where she was informed that the brake line was severely corroded and caused the failure. The vehicle was in the process of being repaired. The VIN was unavailable. The failure and current mileage was 109,000.
The brake lines have rotted out and failed in traffic multiple times without notice. Also the leaf spring hangers rotted and broke. The rear bumper is a rusted mess. The undercarriage of the truck looks like something that was washed ashore. Heavy duty rot. The body and cab inside still look new. Something wrong with the steel in this vehicle.
Multiple brake line failure, and fuel line failure due to to rotted lines along drivers side frame rail. Due to poor quality factory installed components. Three seperate incidents, 2 with brake lines , 1 with fuel lines. Approx. Out of pocket expense so far , (and not completed yet), is over $1,500. 00 for purchased and installed replacement parts.
The contact stated while coming to a stop she depressed the brakes and the pedal went to the floor. She noticed brake fluid all over the road. The dealer told the manufacturer the brake lines were completely rusted. The rotors have been turned once due to accumulation of rust. The dealer told her the recall 05v379000 did not have anything to do with the brake system, just the sensor. Also, the dealer told her that because she did not have an established relationship, did not show loyalty to a specific dealer, and was not a current customer of GMC, they could not fix the vehicle under warranty.
Brake failure- serverely rusted and corroided brake lines. Had to have every brake line changed. This is the second time this has happened to this vehicle; the first time in 2005 with 70,000 miles and the second time was on 10/16/11 with 85,000 miles. Brake lines broke and all fluid came out, no brakes at all had to tow vehicle to garage. This last repair cost me $1200. 00. My truck is used for personal use, normal operation.
Dt:the owner had problems with the low speed brake applications when coming to a stop at stop signs. The abs problems began last year. The owner had to have the front wheel sensors and rings replaced. The brakes worked okay for a while. Then on July 28 2005 while driving at 30 mph and approaching a red light tried to stop but the brakes failed. Could not stop and hit the curb. The owner added a quart of brake fluid and looked underneath and saw the brake fluid squirting out of the brake lines. Then, at home the owner let the vehicle sit and the rest of the brake fluid drained out. Then, the owner called GMC, and told them what happened. He did not think it was normal for the brake lines to rust at 47,000 miles. GMC advised the owner to take the car to the local dealership, who kept the car for one week. GMC sent an investigator who could not find a leak in the brake lines. The inspector was contacted by the owner ,and the owner asked if the inspector had filled the brake fluid and pushed the brake and he said no. The owner asked how can the fluid leak out if brake fluid was not put in. Then, the owner examined the brake lines and saw that they were rusted/corroded. The owner contacted GMC again advising GMC that the inspector had not filled the brake lines. GMC denied the owner's claim. However, the owner did not know why the brake lines rusted. The dealership advised that the owner that he would have to pay for the repair of rusted brake lines. The owner paid the repair cost. Upon inspection of the vehicle the owner noticed the brake lines were only partially replaced. The cost of repairs was $894. 78 for about 4 feet of brake lines.
Brake lines corroded (rusted).
While driving rear brake line snapped, causing fluid to leak out, and resulting in heavy vibration. Will be hard to stop.
Brake hose@ rgt frt is rubbing rim when turn wheel and has been.
Brake line that connects to rear driver side tire is cutting through/ towards the bed area, and it is rubbing against the frame due to poor design of vehicle.
