Took this off my project this weekend, can't believe some people! (Bought the car this way, wasn't me!!) Hard to see, but has some really deep grooves worn into it.
I had a friend that had a 1972 gran torino, he brought it to me telling me there was something funny with the brakes. When I got the wheel off, I couldn't believe my eyes!!! The caliper was gone, and the rotor hub was the only thing left!!
