Two problems related to brake abs warning light have been reported for the 2005 Chevrolet Avalanche. The most recently reported issues are listed below.
Brakes failed under hard stop (highway, in motion). Intermediate steel brake line failed to rear brakes in a mode of rupture due to corrosion. Abs light had been on with service brake message as well. All other steel lines were corroded and contacted gm. 2 other silverado line vehicles owned also failed this year due to corrosion. Gm response was that no recall existed. Replaced all steel brake lines in vehicle with stainless aftermarket lines. After multiple contacts with gm customer service, I was told to save my receipts for repairs. This is an incorrect material specification, latent defect and gm needs to be held accountable. 3 vehicles that I own with the same repair in 8 months. Inexcusable!.
When pressing the brake pedal the abs light comes on. The truck slows but just prior to stopping the abs feature activates and the brakes make an annoying grinding sound then stops.
