While driving in town I noticed my brake pedal was feeling soft, the next time I depressed the pedal, it went all the way to the floor and the vehicle would not stop at all. I coasted into a parking lot and used the emergency brake to complete the stop. I looked under the vehicle by the drivers side door and witnessed the fluid dripping out of the brake lines. The car was towed to a local mechanic, where he discovered all four lines had failed at a point where all the lines were held together by a mounting bracket, just under the driver's side, and mounted to the frame. Had I been at higher speeds and had to make a quick stop the outcome would have been much worse.
2000 GMC Sierra brakes complaints
Page 2 of 9: complaints 11 to 40 of 228, newest first, as owners wrote them.
I own a 2000 gmc sierra crew cab short box 4 by 4. I was driving down the road and heard a grinding sound, so I thought to limp it home. Bad idea, I was the two bolts that hold your caliper on, so that is your whole brake system, well it made my wheel lock up and caused me to loose control and hit the curb where I bent my rim and popped my tire, so I replaced the two bolts on driver back side and checked the passenger back side and those two bolts where loose. Very scary. So I tighten them both and like I said replaced the other two on the driver side. When I seen the way it was set up I was shocked because it was not a good idea and never seen calipers bolted like that, this happened three months ago well today I was driven and heard the same noise again and before I could stop all the way my tire locked up again but this time I was in control and stopped ok. I am freaking out because I have a five year old special needs daughter and don't want her to be in my truck if it decides to lock up and flip.so I went to the same auto shop and had it replaced again. Like I said I seen a lot of brake systems and this way they have it is not same and I imagine has caused deaths, if not yet it will, it about made me roll and screwed up my rims and new tires, I don't know if I should sell it because I do not have money to get them all replaced. So im going to see if there is a recall and if not there needs to be. My mom have a 2004 silverado chevy and I owned a 2002 before and both trucks brake system are different. I want to know why they are like this and why they change a good thing. I hope this was helpful. So if you hear grinding in tires make sure you stop and get it towed.
The brakes in my gmc pickup truck failed due to severely 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.
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 federal safety agency.dot.gov/vehiclecomplaint.

While driving west on central avenue in pedal, I applied the brake pedal to slow the vehicle to make a right turn onto stevens street. I felt no resistance and looked down to see if I had missed the brake pedal somehow, but it had pushed with no resistance to the floor. Pumping the brakes repeatedly, I was able to obtain a small amount of braking and made the turn on stevens. Stopping at deep south cycles, I told the mechanic what had occurred and he noticed the rear wheels were very hot, indicating rear brake lockup. Indeed, at that time they were still locked up. We checked the emergency brake to see if it was applied and it wasn't. The brake fluid level was the proper level, also. After the brakes had cooled down I drove the truck a short distance to a repair shop on central avenue where they replaced the rear brake calipers and pads. They stated that the rear rotors had turned blue from the heat, and added that they "had seen a lot of failures of gmc brake calipers."
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.
Tl* the contact owns a 2000 gmc sierra. The contact stated that while driving 10 MPH, the ABS and hydraulic brakes failed without warning. The contact was able to take the vehicle to the dealer for diagnosis but the dealer was unable to diagnose the vehicle. The manufacturer was not notified and the vehicle was not repaired. The approximate failure mileage was 160,000.
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 hydraulic 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.
The first incident I was pulling out of a parking spot and noticed my brakes were gone. The pedal went all the way down to the floor. Got out of the vehicle and there was brake fluid leaking from underneath the truck. Took it to the mechanic and was told the brake line was rusted. Had it repaired and since then we have had 4 additional incidents.
While backing my truck up to attach a trailer, I pressed on the brake pedal and it went to the floor. I had absolutely no braking ability. My truck ran into the trailer, causing minor damage. Upon inspection, it is evident that there is a failure of the brake line that runs to the driver's side rear caliper. A significant amount of brake fluid can be seen and smelled in this area. I am not able to drive the truck. It will need to be towed to a repair shop for what I assume will be expensive repairs.
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.
Tl* 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 *bf 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
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 got into my gmc applied the brakes before starting the truck and all of a sudden the brakes went to the floor. I got out and discovered fluid dripping from under the truck, on the drivers side, about in line with the back of the drivers seat.
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!!
While pulling a small enclosed trailer and going down a hill I experienced a complete brake failure. I had absolutely nothing for brakes. I ended up going through a redlight and missed any vehicles in the intersection, started to downshift to slow my speed. Crossed over an intersection for a bike trail with noone in the way. Then had to make a hard right turn to go under a train tressel narrowly missing an on coming car. When I finally got the vehicle stopped I had dropped vertically 80 + feet in the matter of less than a half mile. On the ground was a puddle of brake fluid fromthe corroded brake lines that had burst rendering my truck in to an unstoppable downhill bobsled. The weather conditions we sunny and 80 degrees. Luckily noone was in my way and I was able to miss any objects and steer the truck to a safe spot. I am also thankful that neither of my kids were in the truck with me at the time of this incident. I feel that there should be some accountability in to what a manufacture uses for vital safety items in a vehicle. Brakes lines should be a part that should outlast the usefulness of the vehicle . Not something that should be a possible failure point any given time. This is a matter of public safety how many more people have to die or get injured due to a cost savings of using regular steel lines on the one part that makes you vehicle stop? I have heard of plenty of people with multiple vehicle types who have had their brake lines fail. This is just unacceptable thank you for anything that you may try to do on this issue .
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.
Complete hydraulic brake failure without warning. Check engine light only came on after the vehicle was stopped with the emergency brake. The dealer said that the front brake had stopped working sometime ago, only the rear brake had been working. The dealer "replaced rear pads and rotors and parking brake shoes, found four busted brake lines, replace all front brake lines, master cylinder to ABS module (2) and from module to front brakes(2)."
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.
Brake line to the front passenger wheel blew apart causing the brake fluid to leak out, and dramatically decreased the stopping ability of the vehicle. Had this line replaced by a local repair shop, and was notified by personnel that all of the lines were in bad condition, and needed to be replaced soon.
The federal safety agency 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 federal safety agency 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.
I experienced sudden brake failure in my driveway. There was no warning light,just the brake pedal going to the floor. My mechanic looked at the failed line and said all my lines and ABS unit were corroded and needed to be replaced. He also found my right rear spring hanger was rusted off and the spring was just resting on the body. The rear wheel brake backers plates are rusted off also, and the entire frame is very corroded. This is a huge repair bill that may exceed the value of the truck. This is not normal corrosion. I have lived in nh 55 yrs and have never had a vehicle rot like this. I have a 2000 volvo v70 with 147,000 miles on it with no issues. Obviously gm cheapened this truck up or bought defective parts. I have found hundreds of accounts on the internet identical to mine. This vehicle needs to be recalled before people are killed. I am thankful I was in my driveway and not highway or city driving at the time of the failure. Do the right thing and hold gm responsible. There would be no gm without our tax dollars and they need to make this right. Thank you
Brake failure- severely rusted and corroded 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.
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 separate 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.
