Two problems related to abs brake fail have been reported for the 1997 GMC Yukon. The most recently reported issues are listed below.
Abs fails at low speeds. Pressure will dump, pedal drops or shudders, and vehicle will continue to roll for 30 feet before stopping. Abs self-checks and passes test. I got tired of poor performance and pulled the abs fuse to disable it.
