Approximately one week ago I began noticing problems on rough surfaces with my anti-lock brakes. Whenever the brakes were applied on a rough surface the anti-lock brakes actuated but didn't seem to be stopping the car. I attributed the problem to be simply a function of the rough surface combined with the rainy conditions at the time. Yesterday morning when I started my vehicle the ABS light came on and I immediately noticed a loud clicking noise which continued even after turning off the ignition. I had to remove the 60 amp fuse for the brake system to stop the pump from actuating. I took the vehicle to the dealer and was informed that the electronic module which operates the system had shorted out. This same problem has been experienced by 6 other people I work with here at eglin afb.

The ebcm (electronic brake control module) failed, leaving me with no anit-lock brakes. I believe this is due to the fact that they mounted this electrical system underneath the truck (exposed to all elements) rather than underneath the hood. In fact, Chevrolet must believe the same thing, because they changed the design in 2000 (they now put this component underneath the hood). I know this has happened to many people (see discussion thread "Silverado ABS module failure" on www.4X4review.com/discussions/Chevy/). furthermore, Chevrolet wants to charge almost $1800 to fix this ($711 for just the part, but special tools are required to calibrate it). I think this cost is prohibitive (almost 10% cost of the vehicle) to many people, causing them to neglect this repair and go without ABS. The central point of this complaint is that this is a design flaw and Chevrolet refuses to provide any cost assistance..water can also get into the hydr, pump and brake down the brake fuel, causing brake failure.

- Mount Carmel, TN, USA

The ABS module started running when it did not need to be and would not shut off. I contacted service department at molle Chevrolet in blue springs, mo, and they knew exactly what the problem was because they had seen the same thing several times before. They wanted around $1000 to fix it. I feel like GM needs to recall this component if it is failing with such high frequencies. I don't feel as safe driving without ABS especially in a pickup which is light on the rear end and can slide easily in an emergency situation.
