Driving a well maintained two wheel drive 2004 chevrolet silverado 2500 crew cab pickup at 30 MPH on a suburban roadway. I applied hard braking and pedal went to floor. I was able to shift automatic transmission to low 1 and apply e-brake to stop before crash. Examination of steel brake lines from master cylinder to the ABS module under the drivers floor showed excessive corrosion as reason for failure. The lines that were specifically affected travel over driver side frame rail and are out of sight for routine visual inspection. This vehicle operated in the "salt belt" (new england) and road spray from the left front tire directly impacts this area. After replacing all steel lines with stainless lines (over $500.00 in parts & labor) the brake system worked as designed.

Upon leaving a parking area with a full load of woodchips on my truck my brake pedal suddenly and without any dashboard warning, went right to the floor. Coasting to a stop and applying the parking brake I stopped the truck without hitting anything. Looking under the truck I found the rear brake line had burst. I had the truck taken to my mechanic who stated the entire brake line system had corroded and was falling apart. I was advised to take it to the local chevy dealer to repair due to the extensive length of time to needed to make the repair. The entire brakeline system, ABS pump motor and valve was excessively rusted, corroded through and non repairable and had to be replaced. Repair cost $2,026.47. I am appalled that gm is aware of this problem with the brake line system and I was never notified nor was a recall issued to have this trucks brake lines replaced before they burst and caused the brakes to fail completely, without warning.

When coming to a stop the brakes operate properly until just under 10mph. Around 10mph it felt like the brakes faded away causing the truck to lurch forward. I replaced pads and rotors on the front and back thinking this was the issue. The problem persisted after installation of new brake components. I later learned this was an issue of the ABS kicking and was informed the entire wheel hub assembly had to be replaced to correct the problem. There were no issues with the bearings in the hubs and could not afford the cost of $280 each. Since this vehicle is not driven daily I assumed I could just be cautious and allow extra braking distance to compensate for the problem. In may of 2012 I encountered a situation where I had to make an abrupt stop from a speed of 45mph. As my speed decreased the ABS engaged causing me to lurch forward and I came within inches of crashing into the vehicle in front of me. While researching this problem I found gm recall #05068c front wheel speed sensor corrosion. The symptoms in this document are identical to the issue I have experienced. I have performed the repair procedure outlined in the document and can report this issue has been resolved. However, it took a significant amount of time and one wheel speed sensor had to be replaced. Gm should be required to extend this recall beyond the 2002 model year. I aware of at least 2 other gm truck owners (2005 model year) that have replaced their wheel hubs due to this issue. *js

2004 chevrolet silverado. When decelerating to stop for a red light, the ABS system activated causing the vehicles deceleration to decrease, thus increasing the stopping distance, resulting in a near collision. The vehicle now does this consistently during every stop once the vehicles speed drops bellow 10 MPH. There are no warning lights indicating anything is wrong with the vehicle, which is even more alarming. This problem seems to be identical to that in the federal safety agency campaign id number 05v379000. If there is an problem with speed sensing (as in the federal safety agency campaign id number: 05v379000), the system should be able to detect inconsistent sensor readings and render the ABS system into a passive mode as a fail safe measure.

Dt: the contact stated that 2004 chevrolet silverado failed to stop and crashed into another vehicle. The speed was around 40 MPH when the driver went to apply the brakes and the ABS did not engage. The brake pedal went completely to the floor. The contact was standing up in the vehicle and mashed the brake to the floor. There was plenty time to stop, but the contact's vehicle went sliding into another vehicle. This created a chain reaction with other vehicles. The total of number of vehicle involved in the accident were four. Neither the dealership nor the manufacturer were contacted about the brake failure. A police report was taken. There is a picture of the front end of the drivers vehicle. The problem with the brakes was intermittent. The vehicle has not been checked for the brake problem by a dealership or independent party. The property damage did affect three other vehicles.*ak updated 11/29/05.

I had the following problem with my 1999 silverado as well: while driving my 2004 silverado down rt. 128 in ma. At rate of speed of about 45 MPH the person in front of me approximately 75 feet (?) stopped suddenly. There was plenty of distance to stop. If I was driving my 1968 dodge dart with 1 brake and bald tires I could have stopped. However, while driving the 2004 modern computer controlled vehicle, the truck failed to stop and I rear-ended the driver in front of me. The air bag was not deployed because of the slow rate of speed. The reason the truck failed is because ABS would not stop the tires because the road was rough like a wash board. The truck just kept rolling forward at a slow rate and I could not turn off due to the guardrail and traffic to my right. I watched my new truck slowly hit the person in front of me. They were driving a nissan that just got a scratch on it. My chevy silverado heavy duty 2500 fell apart on the highway. The entire front end of body parts were on the ground. I now have a giant insurance rate that I am disputing. There has to be a stop to these ABS. How did I make it 38 years without helmets and ABS. This is getting ridiculous.
