2001 Chevrolet Suburban brakes problems

On june 25th, 2003, my wife hit another car with our 2001 chevrolet suburban. The driver of the other vehicle was injured. My wife said that she pressed on the brakes and they went to the floor. Our suburban slowed but didn't stop. I told her that she needed to remember how heavy the suburban was and that it was probably because the truck is so heavy and not an issue with the brakes. There was a police report filed, and my wife was ticketed.

Tl*the contact owns a 2001 chevrolet suburban. While driving 35 MPH in the rain, the ABS light illuminated. When the contact turned off the engine, it made a humming sound. He disconnected the module and the humming stopped. The contact took the vehicle to the dealer the following day and they replaced the module under warranty. Three years later, the failure recurred. He purchased the third module and had it replaced by a local mechanic.
