I’ve seen some bad rotors in my mechanic days, but that is the worst I’ve ever seen. Actually, we had one truck that had brakes so worn, the rivets cut the drum into two pieces.
I made the mistake of having my brakes done in Korea the day before Chu-sok holidays began. Half of one brake shoe came unbolted and the shoe flipped around. I had to use my parking brake to stop through half the city of Seoul.
