2005 Yukon XL Denali Traction Control Brake Dragging
My Denali has issues, I know. 211k miles and needs things. Yesterday, the traction control button stopped working (was effectively locking out overly active traction control). Now all four brakes drag. Petal still works, and brakes activate, but dragging is very evident with overheating at each rotor. I removed ABS and TracControl 60amp fuses, but to no avail. I'm planning on R&R all four Calipers/Rotors/Pads, all new lines, draining & refilling brake line, but before I do so, I worry there are electronic issues and/or master cylinder/ABS master issues. Any advice?
