Hello all, first post, searched but haven't found anything online or in this forum for my particular issue.
Truck is new to me, 2006 Sierra Denali AWD. I had it out yesterday in some snow and ice for the first time, all 4 brakes are locking up and rear end wants to come around, ABS not even attempting to work, no sound, pedal feel, or modulation on any surface. However I have no ABS lights, no codes, and fuse is good. Fluid level is good, no obvious issues noted.
Any thoughts? Attached a pic to show her off.....
