While coming to an intersection the brakes were applied and the pedal became soft and when to the floor, without slowing the vehicle down. The transmission was shifted into neutral and the emergency/parking brake was applied immediately in order to stop the vehicle. The vehicle went to the local dealership where the diagnosis was a brake line had ruptured due to corrosion (rust) on the driver side rear line. The other three lines were in a similar state and had the potential to fail at any time. There was no indication on the message center that there was ever inadequate pressure to stop the vehicle with the hydraulic brake system even when it was steered to the side of the road and the brake pedal was applied to put the transmission into park.

The brake lines on my truck rotted off and it cost over a grand to fix them. There should be a recall.
Tl* the contact owns a 2004 gmc sierra 1500. The contact stated that the brake lines were deteriorating and the material was rusted. As a result, brake fluid ws constantly leaking and the brakes had become hard to engage. The vehicle was not taken to the dealer or a private mechanic. The manufacturer was notified who stated that there were no recalls for the vehicle and offered no assistance. The VIN was not available. The failure and the current mileage was 78,000.
All of the brake lines below drivers side door became extremely rusted, thus busting and releasing all the brake fluid at once, leaveingthe vehicle inoperative.
Tl* the contact owns a 2004 gmc sierra 1500. The contact stated that while approaching a traffic stop, he attempted to engage the brakes but the pedal was depressed into the floorboard abnormally. In addition, the contact applied the emergency brake to no avail. The contact stated that in order to stop the vehicle, he had to drive the vehicle alongside the sidewalk. After inspecting the vehicle, he discovered that the brake lines were completely corroded. The vehicle was not taken to the dealer. The manufacturer was not made aware of the failure and the vehicle was not repaired. The failure and current mileage was 80,000.
Tl* the contact owns a 2004 gmc sierra 1500. The contact stated that while driving approximately 50 MPH and depressing the brakes, there was an abnormal increase in stopping distance and time. The vehicle had not been inspected by a dealer nor repaired. The manufacturer was not contacted. The failure was approximately 15 and the current mileages were approximately 61,000.
I own a 2004 gmc k1500 with about 70000 miles on it now. On 10/17/11 at 67410 miles I was doing a normal oil change with the vehicle elevated on a rack. I noticed fluid dripping on me from under the drivers floor area. Upon closer inspection I found almost all of the brake lines leading from the front of the truck to the ABS unit rusted badly and leaking. As I was moving the vehicle from the rack the brake pedal went to the floor. With very careful operation and using the parking brake I was able to get the truck back on level ground. I replaced all the lines leading from the ABS unit to the front of the truck rerouting them along the frame. If this failure had occurred on the highway or while pulling my trailer a serious accident may have resulted. This problem is a manufacturing/engineering defect in many of these vehicles. You should not lose all of your brakes when a line ruptures. The dual master cylinder should allow you to have brakes on the opposite side, gm should recall these vehicles and replace the brake lines with stainless or another engineering fix.
I got into my 2004 gmc sierra 1500 pickup truck and went to stop. The petal went to the floor. I discovered the brake lines were rusted and created a leak causing loss of the brakes. The vehicle has no rust in any other areas. It is obvious the brake lines were corroded well before the normal life of vehicle brakes. I was able to stop the vehicle before an accident was caused due primarily to my experience as a long time police officer. This type of brake failure could cause accidents and fatalities.
Tl* the contact owns a 2004 gmc sierra 1500. The contact stated that he noticed that the brake lines were corroded. There was no warning indicating the failure. The vehicle was not inspected by a dealer nor repaired. The VIN was unavailable. The failure mileage was approximately 33,000.
2004 gmc sierra ext cab with 40k miles has seriously degraded braking power. Upon sudden stops the vehicle wasn't to keep rolling taking far to long to stop. The pedal goes almost to the floor and yet the truck is still moving. The ABS system does not indicate it is working but the wheel s do not lock up to a skid, in fact, I can't get the truck to skid or invoke the ABS system no matter what I do. I called the dealer who said no recalls were out for this problem but this is definitely not right. Dealer says it's normal but I can bring it in for an inspection ( $100) but any repairs are not covered by gm, he acted like he never heard of this before? I have heard of several other gmc truck owners that said they had similar issues only to be charged $800 or more with little improvement. I cannot keep this truck like this, I am afraid I will roll into the back of someone and I cannot tow my trailer ( small bike trailer) for fear of the same. When will gm wake up?
Severe brake line corrosion in my 2004 gmc sierra 1500 pickup. Complete failure of brake system. All brake lines severely bubbled and corroded. Estimate to repair is $2000. The federal safety agency should extend investigation of 1999-2003 model year gmc trucks to 2004 and later model years.
2004 gmc pu trk ABS activation @ 5mph or less trk don"t stop safely.

There is a ABS sensor in between them and the unit will malfunction in this condition which will not let you stop when on dry roads I ran through 2 stop signs trying to stop with 2 feet on the brake pedal this condition is not just with my truck I have over 12 friends that have the same truck 2002 thur 2006 and we have all had this happen to us if you want names and #'s I can get them tw*
2004 gmc sierra 1500 4x4 extended cab / 37,828 miles / driven in pennsylvania - ABS activates at low speed (approximately 5 - 10 MPH) when attempting to stop on dry pavement. When ABS activates, the truck will not stop as expected and have not been able to keep truck from entering intersections. Problem is intermittent but is increasing in regularity. Mechanics have stated this is a common problem with gm trucks and the hub with speed sensor will need replaced or repaired. Issue is determining which hub and sensor is malfunctioning. A recall for the same problem was issued for 1999 - 2002 models under the federal safety agency campaign id# 05v379000.
2004 gmc 1500 4x4 85,000 mi., brakes feel soft and have excessive travel during emergency stopping or when towing. Have replaced front pads with more aggressive pads and no help, have tried bleeding several times to no avail. Personally think the problem lies in the lines from the master cyl. To ABS box as these are flex style lines not hard lines, I have been in the automotive repair business for 40 years and have not had a problem such as this that I could not locate a problem, all components appear to be working properly, ie: booster, master cyl, ABS controller, and calipers. I personally know of several other vehicles from these years with the same problems and gm has not fixed the problems.
The parking brake cable broke when putting our 2004 1500 gmc sierra into park. The vehicle can no longer be parked at an angle or it will roll. A part has been ordered but the vehicle has not been repaired yet. Gmc was contacted but we were told that a recall for a similar situation only effects vehicles made in 1999-2002.
Anti-lock brake engage below 5mph on dry roads. Increases stopping distance dramatically. Truck has less than 6,000 miles. Has been occurring for the last 6 months.
I have a 2004 gmc sierra 1500 z71 pick up and the ABS and check brake lights keep coming on and off. After taken in to shop (dealer) they could not find any fault codes finally late 2008 I had it looked at by a local shop and they believe it is a bad card . Some times it wont go off for months and other times it is none stop.
I own a 2004 gmc sierra 1500 z71 with 32,000 on the odometer. On the morning of 27aug2008 the ABS motor located on the framerail under the driver's seat turned on immediately upon turning the ignition to on. The ABS light came on the dash. I had to continue and drive to work. The light stayed on the whole time. Once I arrived at work I removed the fuse for the motor. Now I have no ABS and the lights are on all the time. This is the second time this has happened on this vehicle. The first time was only a few days after it was purchased. It was replaced under warranty. The warranty has expired and it will cost approx. $900 to repair. After some investigation online, I have found scores of people that have had the same problem. There is currently no recall in effect according to this website. I feel that this is unacceptable. This is a very clear safety issue. Not only does it render the vehicle without anti-lock brakes, it drains the battery if the fuse is not pulled soon after the problem emerges. This could leave someone stranded in a variety of conditions if they were unable to pull the fuse or not a full understanding of vehicle electric components. I am even more disgusted that this has happened twice on a vehicle that only has 32,000 miles on the odometer and cost almost $40,000. General motors should be forced to replace the defective components and/or upgrade to a higher quality unit free of charge to the victim.
Vehicle had less than 20,000 miles when right rear brake disc wore completely out. Had to replace again at 40,000 miles. This only affects the right rear brake. Truck has automatic transmission and parking brake has never been used, and is completely worn out. I know that there is a recall on manual trans mission, but seems there is also a problem on the automatic.
Tl*the contact owns a 2004 gmc sierra 1500. While the vehicle was idling with the brake pedal depressed, the pedal extended to the floor without excess pressure being applied. The failure only occurs at low speeds, such as 15 MPH. He has not taken the vehicle to the dealer. The failure mileage was 100 and current mileage was 28,000.
On or about 12/01/06, while pulling my truck ahead, the brakes failed, causing me to roll into a parked vehicle. On 3 other occasions, my truck has rolled through intersections due to ABS failure. I contacted my dealership about the problems I was having and they referred me to gm. When I contacted gm, they alluded to the fact that they were aware of the defect but then indicated that the brakes work as designed. I was then advised that nothing could be done with regards to the brake system but was given some free oil changes for my troubles. When I did finally receive the 12,000 mile oil change coverage, due to delays in their processing, the coverage was actually for only 7900 miles. When gm was contacted, they refused to correct this error.
Dt*: the contact stated while applying sudden brake pressure at various speeds, there was an increased stopping distance. This was intermittent in nature. The vehicle was inspected numerous times by the dealer who was unable to duplicate the problem. The manufacturer was alerted.
I was traveling at 35 MPH on a city street and had to stop quickly. I applied the brakes and received no response as they went to the floor. The anti-lock system finally started to respond right before impact with the back corner of a van. This resulted in extensive damage to my pick-up and the van. I'm still waiting on the insurance company to fix my truck.
Dt*: the contact stated while driving at an unknown speed, the brakes were applied and failed. When the brake pedal was pressed, it was spongy and went to the floor. The vehicle was stopped without incident. The rear stainless steel brake line had split. The vehicle has not been taken to the dealer for inspection and the manufacturer has not been alerted.
