Brake Hoses, Lines/piping, And Fittings problems of the 2004 GMC Sierra

Rusted brake line.

I experienced a brake line failure on my 2004 GMC Sierra crew cab pickup truck. I was traveling at a slow rate of speed and coming up to a traffic light and the brake pedal pushed all the way to the floor board. The rear emergency brake was used to stop the vehicle. I found the area around the brake module, in the frame area under the driver's area, soaked with brake fluid and corroded brake lines.

Again. My truck had complete brake failure again due to corrosion on the steel lines. This is an otherwise nice truck with brake lines that look like they've been in the ocean their entire lives. Gm dealer quoted over $1,700 to fix. Gm owned warranty company refuses to cover repair. Gm customer service tells me to pound sand.

I was taking my 4 yr old to school this morning with his 1 yr old sister when the brakes completely failed. Upon approaching a red stoplight at 30 miles per hour with three cars stopped ahead of me I pressed the brake pedal and it went completely to the floor. I pulled gearshift to the low position and swerved into the vacant left hand turning lane to avoid the cars stopped at the light. Then turned hard right as to not enter the busy intersection in front of me with no avail. Somehow we were not hit by another vehicle. At that time I pulled vehicle over to the shoulder of the road which ended abruptly and turned into a grassy area of a baseball field where the vehicle finally came to a stop. Gm states that if there is a brake line failure the vehicle still has braking ability. I can tell you first hand that is a totally false statement. My vehicle dash did not display any problem prior to this incident. When vehicle was tow to my home I put key in the ignition to check my mileage and now a brake failure message is displayed. I am very angry with gm for not notifying me of this problem and never had any idea there was an on going issue until today. Myself and my two children could have been killed today because of this neglect. Please do something to rectify this problem because many more gm vehicle will have this problem and innocent people and their families will be hurt or even die.

The brake line ruptured on my 2004 GMC Sierra 1500 pick up truck - inspected by a certified mechanic, all remaining lines need to be change due to corrosion.

Had to stop suddenly at about 20 mph. Brake lines burst due to corrosion. All lines had to be replaced. Cost $756. 87 for replacement.

Rusted out/ corroded brake lines burst while stopping for a deer running out on the road. Was warned of this problem upon purchase of the vehicle in 2010 and personally coated all brake lines b4 winter every year. . . Never saw worse lines! I own classic cars that are twice as old with shiney original brake lines. The fuel lines also rotted out spilling fuel over the top of the fuel tank and on the ground while filling up. All fuel lines and fuel pump connections were severely rotted. Worst I have seen. Dash consistently changes languages rendering odometer non functional. Speedometer is inaccurate some times not even working especially on cold days. Hmmmm rotted brakes+no speedometer+leaky fuel lines=crash,bang boom!. . And I have a car seat in my vehicle! luckly I perform preventative maintenance and drive safely. Still wonder how these issues got swept under the rug.

Traveling south, NY rt. 12. Attempted to slow for a right turn. Signal on, towing an empty trailer approx weight 2000 lbs. Applied the service brake for the turn, pedal went to floor, no brakes. Luckily no incident. Examined the underneath and found that the steel brake lines were routed over the frame on the driver side (underneath body under the driver door. ) when brake line(s) failed, there were no sign of any braking ability. Both the front and rear brake systems were inoperable. The lines had rusted through from apparently road salt or (?), creating a very dangerous situation. Since the incident I have spoke with several other drivers who have experienced the same failure.

I had just had the truck inspected. Was driving home and two blocks from the inspection station when I came to a red light. When I stepped on the brakes the pedal went to the floor. Fortunately I reacted quickly enough to to use the parking brake to stop the truck and keep from rear ending the car that was already stopped. After pulling into parking lot and inspecting the brakes I noticed a puddle under the front left of the truck. Looking closer I found the brake line had rusted through. I returned to the shop where I had the inspection done. He repaired the one line that had burst. I was informed that the other lines looked rusted and ready to burst at anytime.

While driving, needed to slow down for traffic light and the brake pedal went to the floor. I was able to still drive it, as the brakes would stop the truck eventually. Cause was the rusted rear brake line that ruptured. Cost to fix was $400. 00 in addition, on 12. 27. 13, I had the front wheel bearing replaced at a cost of $525. 00. The truck only has 66,600 miles on it.

Break lines had rusted out and burst so the brakes failed to stop the truck. Truck was on a down hill incline and went through a stop light (fortunately it was late at night and there was no crossing traffic. ) had to replace all the brake lines.

I was I 91 south heading in to hartford CT, traffic was heavy and as a result I was traveling appx 20 mph as I entered the ramp exit lane. I stepped on brake pedal and the pedal went to the floor, fortunately I was able to veer into the breakdown lane and avoid hitting other cars. I slowly made it to my place of employment and later had the truck towed home. As it turns out I discovered the all brake lines had corroded and had to be replaced. I contacted gm as I thought it very unusual for all brakes lines to be so severely corroded. They attributed the severe corrosion to the fact that the truck was 10 years old and refused to cover the expense and considered the case closed. By doing a simple internet search I found that this same problem is quite common and my mechanic also informed that gm ( possibly as a result of this being a common issue) has made a available a brake line replacement kit.

The contact owns a 2004 GMC Sierra. The contact stated that while reversing into her residential garage, the brakes failed. The contact mentioned that after inspecting the vehicle, she noticed that one of the brake lines had fractured and all the rest of the brake lines were completely corroded. The vehicle was not taken to the dealer. The manufacturer was made aware of the failure. The vehicle was not repaired. The failure and current mileage was 78,000.

Vehicle in front of me stopped suddenly. My brakes failed as my foot/pedal hit the floor. All I heard was buzzing. I hit the vehicle in front of me. Mechanic showed me the rusted out brake line that failed. Advised me that the abs pump just plan emptied my mc to make up pressure loss. My complaint isn't so much the fact that my brake line rusted out as it is a 10 year old truck, (although stainless lines with steel connectors would be a huge improvement). But my complaint is that the abs systems in these trucks, and maybe other vehicles are flawed. Back before abs came out, if a line was damaged or failed for whatever reason the separated reservoirs in mc's would at least give you front or rear brakes to stop. That was the best single design improvement manufacturers made to brakes, and I've been driving when mc's only had one reservoir. To have a complete mc drained for a line failure is ludicrous.

The contact owns a 2004 GMC Sierra. The contact stated that the brake pedal became stuck to the floor board. The vehicle was towed to the dealer, who inspected the vehicle and found that the rear brake line was leaking due to corrosion. The rear brake line was replaced. The manufacturer was not aware of the failure. The failure mileage was 97,047 and the approximate failure mileage was 99,000. Updated 11-04-13 updated 11/8/2013.

Driving on the freeway, I stepped on the brakes to slow down as traffic was heavy in a area that is slow in the morning. The brakes started to slow me down, then without warning the pedal went to the floor and I could not slow the truck. I took action and moved onto the next lane to avoid a crash. I continued to apply the brakes which only worked a little bit until I came to a stop. I had the truck towed to my house. Upon inspection, one of the four brake lines that run along the outside of the frame under the drivers seat had burst due to extensive rust. In fact all four of the brake lines in this location had extensive rust. I had to have all for replaced.

Upon applying brakes to shift into reverse, pedal went to floor and all warning lights came on. Had truck towed to garage, and upon inspection a metal brake line had rusted out. After replacing brake line garage was bleeding brakes and another line failed. Was told by mechanic that I should have all the metal lines replaced because of sever rusting of the metal. This seems to be more prevalent in general motors than any other brand. I was told that the use of salt brine solution in our area for winter freezing is the reason behind this. I was told that the mechanic is seeing at least one vehicle a week with this problem.

Brake lines completed rusted out. Purchased from a GMC/chevy dealer with no notice of this issue. They knew about the issue and this should have been fixed. Still no recall. I guess not enough people have died yet.

I was backing out of the driveway and the brakes went to the floor. The brake lines were severely rusted. They look like the are 50 years old.

Brake lines rusted and failed causing the brake pedal to go to the floor.

Brake line failure as an emergency stopping procedure was in place. Vehicle eventually stopped, but rear ended the forward vehicle. Brake line corrosion in hard piping was diagnosed as the problem as the hard brake line ruptured.

I was leaving my driveway and completely lost all brakes and could not stop. I had to slam on the parking brake to stop. A brake line blew. All the brake lines and fuel lines are completely rotted. This vehicle isn't even 10 years old yet. The fuel line and brake lines are a major safety issue. This truck is a 2500 and I use it for towing trailers if that brake line went while towing it would have been a major accident. The entire underneath of this truck is so rusted the frame brake line and fuel lines are terrible. Someone is going to get killed from gm's cheap steel.

All brake lines are rusted about into. . . One busted, I had been on interstate for two hours and luckily I pulled into my driveway and lost all brakes. Brake lines should not be in such a rusted state for this truck, gm should be made to recall for this problem . . . This is life threatening under such conditions! and should be addressed as soon as possible.

Brake lines rusted through at left side just below drivers door, which resulted in a loss of brakes!!!!! after further inspection all brakes lines are severely rusted and must be replaced. This is only a 2004 truck!!!!!!!!.

Entire brake line failure do to rusted brake lines.

Front brake line failure due to corrosion, in June 2012 have to replace entire brake line system.

All brake lines on my 2004 GMC Sierra pickup are rotted and need to be replaced, the truck has 48,014 miles on it. General motors needs to step up and assume responsibility for this before someone is seriously hurt or killed, if no one has been already.

My vehicle has 76,800 miles and all of the brake lines are rusted and need to be replaced. I understand that there may be a recall for this problem. Please foward any information related to this issue.

While at our town dump on the 2nd of November of 2011, I proceeded from 1 drop off location to the next (as usual), when as I slightly depressed my brake pedal to slow, the pedal went right to the floor. I almost ran into another vehicle had I not depressed my emergency brake. There was nowhere to turn to as vehicles were everywhere, "wow"! not knowing what was wrong, I continued to the next drop off point with virtually no brakes. I used the e-brake again to stop. I told the dump attendant what just happened and he said, "that's probably why you're spewing what looks like brake fluid from your left rear. Sure enough, upon inspection the line blew. I got the vehicle to the local GMC dealer. Long story short, they wanted $360 to fix the brake line. Seth the service manager said it looks like the rest of the lines don't have much time left either. "not good!" I got the vehicle home, called my son who is a mechanic for a local Jeep dealer and he fixed the last foot or so of the brake line where it blew. He said "dad come here". He showed me under the hood where the visible brake lines are virtually rotted and probably ready to go. I am partially disabled and out of work. I couldn't afford to have the dealer replace the whole brake line let alone now having to replace all the lines! I saw on the internet that this is an ongoing problem. Why is there no recall on this? if I were somewhere else going even faster, this could have been bad. Why are the car companies not required to use higher quality/more corrosive resistant lines? yes I understand that would raise the sticker price, but for a life? this is brakes on something that rolls at very high speeds we're talking about here and nothing is being done about it as far as I can see? plus my truck is less than 7 years old as well as all these other vehicles and I had only 84,375 miles on it when it happened. Recall?.

The contact owns a 2004 GMC Sierra. The contact stated when he accelerated and attempted to shift gears, the brakes were applied and the brake pedal extended completely to the floor board. The vehicle was towed to a dealer who diagnosed that the brake line was defective and would need to be repaired. The vehicle was repaired. The manufacturer was notified, but did not assist with the failure. The failure mileage was 50,000 and the current mileage was 60,000.

The contact owns a 2004 GMC Sierra. The contact stated that the brake lines and fuel pump was corroded. The vehicle was taken to an independent mechanic. The technician verified the failure and replaced both the brake lines and fuel pump. The manufacturer was made aware of the failure. The VIN was not available. The failure mileage was 40,000 and the current mileage was 60,000.

The contact stated the front brake lines were rubbing against the caliper, causing a hole/loss of fluid, and failure in the brakes. The vehicle was taken to a dealership, where they replaced the brake line, and placed a rubber boot where the wearing occurred. The dealership said defect was a result of the suspension modification to the vehicle. The contact took the vehicle to another mechanic, who stated the rubber boot would not stop the wearing, and the modification could not have caused the problem.
