Pull the ABS fuse and the grinding will go away because your ABS doesn’t/won’t work. Service Stabillitrak is giving this away that the ABS is messed up. Did they change your brake fluid? Old fluid can eat through the modules. You will want to get them replaced for the issue to go away. When you say the brakes grind does it feel like it’s not really slowing down?
Packer fan living in Denver here; best win. Beat KC, earned a WC spot and the chiefs lost. 1 and 3 ARE different.
