Went to stop at traffic light and experienced brake line rupture due to excessive rust. Had to use emergency brake to coast to a stop. Fortunate no cars were in lane. $1200. 00 for repair of lines.
Brake line failed and broke, upon inspection all brake lines were corroded and brittle, had to replace all brake lines.
Heading into parking spot at walmart , applied brakes would not stop , heading head on into parked car , slammed emergency brake , put into neutral , finally stopped . Had to have towed to mechanic brake lines all burst due to rust , mechanic said cost to fix , approx. $1000 or more ? which I don't have . Thank god I was going slow and didn't cause any injury , pour design and pour quality parts per mechanic on gm's part , notice a lot of complaints on these era of trucks.
Brake line ruptured leading to complete loss of braking. Hit car in front of me as it came to a stop. This is the second time that the brakes have failed due to brake line rupture due to excessive corrosion of the brake line metal. Please force gm to issue a recall.
I was on my way home from an event this past Saturday heading to drop off my son. After dropping him off I continued home. I was traveling about 35 mph when the light turned red and I depressed the brake and was terrified when it went down to the floor. Although I have as able to come to a stop without incident I have as still terrified. I am a disabled veteran with a heart condition and could have had a heart attack. I had my truck looked at by my certified mechanic and he told me that my brake line ruptured due to rust and it will cost me around $1000. 00 for repairs. I have had many many cars and trucks in my lifetime and never ever experienced any problems of this nature. It seems to me the manufacture would allow for these northern conditions with the parts they use in production.
Tl-the contact owns a 2001 GMC Sierra. The contact stated that while driving 65 mph, the brake pedal was depressed and the brakes failed to respond. The contact had to use the emergency brake to stop the vehicle. The independent mechanic diagnosed that the brake lines had rust build up. The independent mechanic repaired one brake line. The manufacturer had not been notified. The approximate failure mileage was 170,000. Ne.
Experienced complete failure of the braking system. Fortunately the vehicle was only traveling 15mph and in an area that wasn't congested with traffic. I was able to stop by using the roadside berm banking and avoided any further damage. Vehicle was towed to a nearby gm dealership where it was determined that both brake lines had corroded so badly it caused the lines to rupture resulting in an immediate loss of pressure and complete brake failure. Just days earlier I had the brakes serviced at a different gm dealership near my home and there was no mention of this condition nor the previous reports of this problem from other owners as noted on this web site. Even if gm or the NHTSA does not deem this issue frequent enough to issue a TSB, at minimum a service warning/recommendation should be issued to gm dealerships and other registered service providers alerting them to inspect for this condition while servicing the braking systems for these model years. Death or serious injury can and most likely will occur as there are many vehicles from these model years still on the road.
It was snowing and icy outside. I attempted to brake for an upcoming red light. The brake pedal went completely to the floor. I had very little braking power. I steered to the curb to avoid traffic in the intersection. I jumped the curb and came to a stop against a power pole. Damage to the power pole and to the front of my truck. One of the steel brake lines ruptured. Upon closer inspection, all the brake and fuel lines were severely corroded.
Brakes hydraulics failed when trying to stop. Truck is in the shop now. The consumer stated the vehicle lost hydraulic pressure without warning. He was traveling 10 mph towards a busy intersection. Fortunately, he was able to turn into a parking lot and use the parking brake to stop. The rear brake lines on the vehicle rusted and leaked brake fluid, which resulted in the loss of pressure.
Front brake line failed. Completely rusted, it blew out inside one the clips that hold it in place. Horrible design. Truck is sitting in my driveway because I cannot afford to repair brakes. Estimate was over 1500, just to replace the lines, with coated steel, not stainless. Fuel lines are all rusted as well. All need replacement.
While driving to work in the morning, applied brakes and the pedal seemed to go down further than normal. Was exiting freeway and appied the brakes, the pedal went down to the floor but the vehicle stopped. I then pumped the brake pedal and it went to the floor and the vehicle started to roll. I was able to pull off to the side of the exit ramp and get vehicle to stop by putting it into reverse then park. It now had complete brake failure. After inspecting under the vehicle noticed that a brake line had rusted through and failed. This one line failure caused both the front and rear brakes not to apply at all. After inspecting further noticed that all the brake lines have severe corrosion and look like they could fail at anytime.
On 12/14/2012. I entered a controlled intersection, went to apply brakes and brake pedal went to floor. Truck stopped, but I needed to apply a lot of pressure. Checked brake fluid and found it was a pint low. Added brake fluid, but brake pedal still needed to be pushed to floor to stop vehicle. Brought truck to mechanic on 12/18/12. They put truck on lift, found entire brake system was corroded. The back plate was also corroded. To repair, all brake lines, bolts need to be replaced, as many parts have rusted away completely. Estimate is over $4,000 to repair.
The chassis brake lines on my 2001 GMC Sierra 1500 are rusted to the point that they are falling apart. I noticed last week that the brake pedal feel is starting to get mushy. After inspecting the entire brake system I discovered that all of the hard chassis brake lines are rusted and flaking apart. I can no longer safely drive this truck until these lines are replaced.
This brake line rupture happened while my wife was @ 15 mph stopping for traffic . How she managed to stop I don't know. She does not like driving this GMC 2500 hd pickup because it is scary for her, after this brake line rupture she will probably never drive this vehicle again. Thanks general motors a bunch for the nonexistent warning about this common occurrence. The general motors profit means more to them than the safety of their customers precious families.
Brakes failed due to rupture of rusted brake line, no warning light while driving on the interstate. Was barely able to stop by pressing brake pedal to the floor. Abs did not activate. Took vehicle to mechanic. Multiple brake lines rusted out.
Brake line ruptured when attempting to stop at a red light. Had to veer into adjacent lane to avoid rear ending truck stopped in front of me. Very fortunate!.
While bleeding the pass. Rear brakes I had a very sudden lose of pressure on the peddle and the peddle went right to the floor of the truck when pressed. After looking under the truck I noticed that I had a brake line rupture along the frame under the drivers seat. After further inspection I realized that all of the brake lines in that area were very rusted and in need of replacement. Luckily I was not driving the truck and no accidnet occured.
I was very lucky my children were not hurt, they use the truck all the time. I went to move my truck in the driveway, the brakes hit the floor. I got under the truck and saw that brake lines are really rusted bad. I haven't had a brake line problem since the 1960s. Read that GMC and chev brakes are now all falling part for anyone who bought them in the last 10 years. GMC / chevy choose to put people at risk.
Upon starting the truck, the brake pedal went right to the floor and brake fluid drained under the drivers side door. A brake line rusted through causing a lack of braking power. There were no alarms prior to the failure. The truck is not drivable in this condition. None of the brakes grab and if this happened on the highway, someone would have been killed. Upon examination, all of the brake lines are rusted and will need to be replaced. Since gm does not manufacture replacement brake lines, each line will need to be bent and fitted by hand. I understand that NHTSA is investigating the problem and says there are 6. 2 million vehicles that are possibly affected.
