Terrorist brake pads.
Must spend trillions of dollars to combat the trumped up issue.
Likely to replace pads, just difficult to pull apart and start replacing parts on a truck with 1300 miles. But the choice is mine cause it bugs the crap out of me. Spend 3 hours cleaning it top to bottom, drive a hundred miles and the front wheels have crap all over them. It's not like I took it on the autobahn.
My GM's were all good. The '02 Silverado had 123k and still on original pads and rotors. The Denali had 67k on when it needed pads. The G8 OEM rotors were known to warp, mine did. Replaced those and the pads at 12k. Yet never had pads this dusty on anything I've owned.
Guess I knew it was coming as for years I've seen Ford trucks and SUV's driven around that aren't well detailed and maintained with brake dust turning the front wheels especially into a much darker shade of color compared to the back wheels.
