Left house and abs brake light came on, shut the truck off and abs brake pump under truck would not stop running even with key off. So had to take fuse out. At that time I drove back home, but if you push down on brake it will go to the floor. June 2014 had truck in shop to have all brake lines replaced and fixed at auffenberg in carbondale illinois due to brakes all of a sudden going out and all lines rusted and now 2,500 miles later this happens also the emgerency brake is not working either. So was there more damage done from all this that should be on recall and us not paying the bill for these defects.

While towing my boat I experienced brake failure. The pedal went to the floor with no pressure. Brake warning light did not come on. We were on a dirt road with no traffic and were able to stop without incident. After inspecting the brake lines a leak was found in one of the lines under the drivers side door before the line enters the brake modulator. All the lines are rusty and need to be replaced. I contacted the GMC dealer and although they have seen the problem before they are unaware of any safety problems with the brakes and that gm has no fix for the problem. They estimate the cost to replace the brake lines to be about $1200.

While traveling in my 2003 GMC Sierra truck at approximately 45 mph I stepped on the brake pedal to stop at a stop sign and the pedal went 3/4 of the way down to the floor, then the brake light came on and the truck did not stop as quickly as it usually does ( glad I was not going any faster) . Upon checking the truck it was discovered that the front drivers side steel brake line had a hole in it due to corrosion and there was no brake fluid in the master cylinder .

Driving on west stone drive kingsport, TN, a vehicle cut me off trying to get thru a traffic light, I locked my brakes down hard as I could, I could feel the abs system working, I was able to stop about 12 inches from the other vehicle. When I pulled out after the light changed to green, I was traveling down a slight grade, depressing my brake pedal lightly, the pedal went all way to the floor board. . I took the truck to a local shop to have it checked, one of the brake lines behind left front wheel had ruptured. When the mechanic started the repairs, he called said all lines on this truck were extremely rusty, (he asked what I wanted to do) I said fix it right. In making the repairs all lines were replaced. . I have pictures of all lines that can be sent. I also have all of the brake lines that can be looked at and or analized.

I was parked on a sloped driveway (about 10 - 15 degrees). I started the engine, stepped on the brake pedal and took the car out of park into drive. Brake pedal was normal. I started to roll forward and when I pushed the brake pedal the car did not slow. I slammed the brake pedal and it went all the way to the floor. At this point I went off the end of the driveway onto a 45 degree downward sloped lawn; then into a wooded area at the top of a ravine. I slammed into a tree. The car was judged a total loss by my insurance company. I did not get a brake warning light. The airbags did not deploy. The car was serviced at a union park GMC (wilmington, DE) two days prior. Including brake inspection. Cause of brake failure was determined to be ruptured brake line. Both front and rear brakes were failed.

I have a 2004 GMC Sierra that has an electrical issue with the abs or brake system. The brake light, abs light and service brake system light goes off at random times. Might have something to do with the air conditioning because the a/c draws power from the battery and I can see that a certain level the indicators go off. Most of the time the lights chime and blink when I apply the brake but it also has happened when just turned the truck on. I've replaced the rotors and pads to still have the problem. I'm not sure if it's a ground or sensor that is failing. I've found TSB for regrounding, failing sensors, or ecbm. Still haven't found the correct diagnosis. I just hope the abs functions when I need it.

The first day I noticed that the brake pedal went closer to the floor before the brakes activated. The second day the pedal nearly touched the floor and then the brake warning light came on. I took the vehicle to my neighborhood indy tire center where they quickly determined brake line failure near the left rear wheel. The brake line had rusted completely causing a hole and rapid loss of brake fluid. A new teflon coated main brake line and fittings was installed along with new brake fluid. Other brake lines were examine and found to be rusted but not compromised. The total cost of repair was $461. 38.

Applied more pressure with 2 feet and brake pedal went to the floor with no warning at all. No brake light on dash came on just went to floor. Was determined by my mechanic that the brake lines had rotted and I had a catastrophic brake failure loosing major brake fluid at the accident site.

Stepped on the brake to put the truck in gear when it was noticed that the brake pedal went all the way to the floor! backed up, pulled forward, there were no brakes! vehicle was carefully driven home using back roads and transmission braking along with limited pedal braking. Brake light came on just before arriving at home, 10 miles down the road. The truck is presently in an independent repair facility. All metal brake lines are to be replaced at significant cost to me. Upon inspection it is apparent that the brake lines are more of substandard material. All metal lines show excessive corrosion and deterioration for a vehicle of this age and mileage. The truck is my wife's and was rarely driven during winter months.

Failure of abs module caused abs light and red service brake lights to come on. Replacing both front hub bearings (including both front abs sensors and wiring) and repairing the ground strap on the frame for the abs system did not fix the problem. Service brake system has new calipers ,rotors,and pads and a full inspection revealed no problems or failures. Abs module is still on vehicle but will be replaced next.

: the contact stated the brake light illuminated. The contact pulled the fuse to the abs to have braking power at low speeds of 15 mph. There is an NHTSA recall, 05v379000 concerning the service brakes, hydraulic: antilock, however the recall did not remedy the problem. The dealership cleaned the sensors; however the vehicle is still having the same problems as indicated in the recall. The dealership would not offer a second repair without charge under the recall.

About three years ago I took my 2000 Sierra truck to my GMC dealer after experiencing a few low speed abs activations and brake failures causing me to drift into oncoming traffic. Since tandom log trucks are frequent travelers on our local roads, I wanted to resolve the problem right away. My GMC service manager informed me that the only way to correct the problem was to replace the front hub assemblies containing the wheel speed sensors at a cost of $500 each for parts only. I decided against that idea and opted to remove the abs fuse under the dash board. I kept inquiring at the dealer about any gm sponsored repairs and finally read about the August 29, 2005 recall notice which involved cleaning, sanding, and lubricating the wheel speed sensors. The recall service work was done on 10/13/05, according to service bullitin #05068, but my truck continued to drift into traffic as before. This time I removed the abs fuse from under the hood so I could finally use the cruise control again. The service manager has since told me that there is no authorized follow up procedure other than to replace the hub assemblies or speed sensors, at my expense. The brakes function adequately without the abs fuse, but the red brake failure light on the instrument panel is on continually, as well as the amber abs light. If I go back to removing the interior abs fuse, the red light will go out and should be available to indicate any other cause for brake failure, but I sacrafice the cruise control. Gm has admitted that they designed a defective abs system that is prone to rust and corrosion in certain "rust belt" states and provinces of canada and they are aware that these vehicles have been unsafe to operate. The ineffective recall repairs to my truck cost general motors $46. 88 on the invoice and yet they expect me to pay about $1,200 to really repair and replace their defective parts. I don't think so.

Anti lock brakes fail at low speeds contact must use parking break and place truck in neutral in order to stop. This causes extended stopping distances. Almost crashed 4 times due to brake failure. Actually made contact with another vehicle but no damage occurred. No brake light warning came on. Problem progressed with time. 10 mph and under is the speed at which problem occurred. Vehicle was taken to dealer for repair on 4/11/05. Problem was fixed at a cost of $877. 09.

While applying the brakes, the abs and brake lights would come on intermittently. The dealers mechanic stated that the abs brakes needed to be replaced. The abs failed as a result of abs switch failure. Abs motor stays running even with ignition key removed and engine off. The dealer quoted a price of $900. Dollars for repair. This seem to be quite common.

Abs pump runs even with key off! only way to stop it is to pull fuse. Abs and brake warning lights stay on all the time. Did not initially notice the problem until I made a tire screeching panic stop. Dealership stated no recall.
