Ten problems related to brake electric antilock have been reported for the 2004 Chevrolet Silverado. The most recently reported issues are listed below.
When placing the vehicle in drive/reverse after start up, the on board diagnostics reports "service brake system". A complete brake inspection has been performed with no indication of any type of issue. This is an intermittent problem. If the diagnostics reports this failure, I can turn the vehicle off and wait a few seconds and re-start the vehicle with no failure report. I took the vehicle to the dealer, melbourne Chevrolet, melbourne, FL, they reported that they were aware that if a vehicle remained idle for any period of time, this type of code would be a result of salt water corrosion. I have 28,000 miles on this vehicle. I have done some research and found that gm has had similar recalls on the Silverado's but not for my year/area.
Hydraulic brake system is ineffective in stopping this vehicle. Brakes are spongy and go to the floor when stopped or if hard pressure is applied. This vehicle would not stop if a child ran in front of it. Three attempts to repair and now we are told it is part of the design and if we used it more this would help. The newer models do not have this system. I wonder why?.
My 2004 Chevrolet Silverado has dangerous brake problems. The brakes give way unexpectedly with the pedal going all the way to the floor. This has happened four times in the past two months- each time the situation was different. The first time I was just parking the car in the garage moving it from the driveway. The second time I was pulling a trailer loaded with a tractor across town and the only thing that stopped me was the electric brakes on the trailer. The third time was moving it across the yard. The last time was in the city driving to a store, I was going down a hill to a red light. The pedal suddenly gives way and goes all the way to the floor with no warning. It then begins working again just as suddenly as it quit. The brake pedal will snap back up and the brakes start to hold again. One time it took 15 minutes before it started working again, the other times it was a matter of 3 to 5 minutes without brakes.
Abs pump motor running constant even when vehicle is off and key is out.
A 2004 2500 hd Chevrolet truck hit consumer's son in Ford ranger. The Chevrolet momentarily stopped, and then hit consumer's son with a light impact. Recall id 05v043000 was issued on brake problems & difficult steering. The tie rod end broke, and it appeared they were not well built to break with only a light impact. Consumer filed a complaint with Chevrolet. The Chevrolet driver sustained chest problems and heart racing from the accident.
Not had a brake problem until applied brake pressure. While driving home saw road construction and hit brakes and slid to what seemed a long way. Felt there was extended stopping distance. This was the first incident of this type. This did result in an accident, striking vehicle in front. No repairs. One person died as a result of this accident. Consumer felt brakes contributed to this accident.
In January 2005 the consumer's husband was driving at 30 mph when the brakes and steering locked up. In January 2005 there was a light snow . The consumer took the vehicle to the mechanic and found out that the brakes were corroded. The vehicle had a little under 20,000 miles on it. On August 31, 2005 the same thing happened and it was wet outside. The air bags did not deploy. There was no for warning.
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.
Going downhill on a s curve, I was applying my brakes to slow down and pedal went to the floor had to pump a few times to get brakes.
Mushy brake pedal goes almost to floor and requires extreme pressure on pedal, especially at slow speeds, worse with load. No consequences yet. Problem since new and dealer said brakes would wear in ok, now 40,000 mi and problem worse.
