While vehicle was under warranty I complained of fading brakes while traversing rough spots in roads.dealership mechanics said it was the ABS system. He said I could disconnect it?but I chose not to. Now my 1999 Silverado has an even bigger problem. While performing a gentle stop the brake pedal becomes hard and vehicle will not stop unless I stand on the brake pedal. I crashed through my garage door the last time this happened. My brakes were inspected and they are all in good order. The mechanic did however notice that the ABS was on constantly. ( so does someone have to die before action is taken on this matter) there is numerous complaint about the ABS system in this truck.

Like so many others, my ABS system has gone out on my 1999 Chevy Silverado, I was simply driving to town when the light came on, 34,000 miles on the vehicle. The motor kept running even when the vehicle was turned off, I immediately proceeded to my asc certified mechanic who reviewed the vehicle and informed me my ABS module is shot and the estimated repair cost is $1000+ (partially due to no aftermarket parts available.) so not only is GM unwilling to acknowledge the problem, they are compounding the pain for owners by holding a monopoly on the repair part. Unacceptable - a recall is in order - this is a serious safety issue GM is not addressing.

1999 Chevrolet Silverado has two problems with brakes. First problem is that truck continues to go full speed after hitting brakes if there is any uneven roadway or if road is wet or if any number of other conditions exist. Very scary when it won't stop. 2nd complaint is ABS module went out at 34,000 miles and 42 months. Was told that it was not under warranty. Spent $900 to replace, did not solve any of my braking problems. It is scary to drive because you never know when it will decide not to stop. Cannot identify a single date, the stopping problem has happened too many times to enumerate.

The break pedel becomes rock hard and the truck will not stop have to use the emergancy brake when the antilock brake fuse is removed the brakes work fine. Before I removed the fuse was almost in many crashes, if I had not used the E brake!!!!!!!!!!

ABS brakes severly resist the operators attempts to bring the vehicle to a stop at slow speed. The brake pedal vibrates but increased pressure by the operator will not being the vehicle to a stop. You have to take your foot off of the pedal completely, then slam it down with force to get the truck to jerk to a stop many feet past where it would normally stop. This frequently causes a loss of control at slow speed such as pulling up to a gas pump or stopping at an intersection. On numerous occasions, the vehicle failed to stop until it was well into an intersection. Dealer would not repair unless "the ABS light came on" which it never did. Owner removed the ABS fuse and the vehicle stops normally with ABS disabled. Owner investigation revealed that this is a common problem on the 1999 Silverado which requires nearly $1000 to repair, but GM will not cover the repair of these obviously defective ABS systems.

When brake applied at slow speed, truck failed to slow down with constant brake pressure. I almost rear-ended vehicle in front of me. Pavement was clean and dry. I have also been getting ABS chatter when stopping at slow speeds.

Many people simply pull fuse or disconnect ABS pump power and go without ABS because of the cost of repairs. Due to the number of vehicles experiencing the same failure, this could be a significant safety problem.

- Cortaro, AZ, USA

Ecbm shorted out. Located on top of ABS brake pump, attached to frame under drivers seat. Dealer wanted $1100 to fix, $770 part. Bought part $409 (discount) had installed for $300, called Chevrolet service help. No help!! got other recalls fixed at dealer. Dealer nor me couldn't get hold of chevorlet service help. Ecbm located where water can damage it. Seems to be a problem with 1999.

I have talked with over 50 people just in the knoxville area that have had this same problem - a "burnt out electrical delay in the ABS unit" - costing upwards of $1000 to fix. I have put less than 5000 on this vehicle from my date of purchase earlier this year. I am still under dealer warranty and I will be demanding a refund and an explanation. If so many people are having this same exact problem, some people told me it is caused by water from the left tire splashing on the speed sensors, vitrually rendering them useless, then why isn't there a recall?

- Maryville, TN, USA

The ABS motor keeps running after the truck is cut off. The only way to stop it is to pull the fuse, so I have no ABS. GM finds ways to get out of their warranties and could careless that they are creating safety problems. When you pay $26,000 for something you expect it to work and extended warranties should be just that instead of ways to suck out more money from buyers.

ABS pump continued to run with vehicle off. ABS/brake light remain on seems to be a very common problem.

- Front Royal, VA, USA

ABS module fails, and antilock brake are inoperatable. Module is located under the truck on the frame rail. This probably causes water to short it out.

- Murfreesboro, TN, USA

The module that controls the ABS is failing to turn the ABS motor off when the truck is stopped. I have contacted Chevy and they have said there is nothing that can be done but said this is a common problem with these trucks. It was not mentioned at the time of purchase. I have searched the internet concerning this issue and it is filled with message boards complaining of this same issue. How much more has to be done to start a recall campaign for this?
