I have a charger and road runner with disc brakes.
I have had extra rotors for years removed from cars over the years and have other rotors I can’t seem to place.
The Road Runner and Charger brakes have rotors that measure 11” OD with backside openings that measure 7” diameter.
I thought I could use these other rotors but when I measure them they have 11-3/4” outer diameter and backside openings 7-3/4 diameter.
The service manual says I should have these measurements in the car yet the ones I have are smaller. I have the Kelsey-Hayes single piston calipers. My installed rotors are closer to an inch. That is what I see in a 70 Dart service manual yet I know the cars did not have disc brakes I installed from an A Body.
The other extra rotors are 1-1/4 thick. The bearing races are the same. They would probably fit but the pads shouldn’t rub correctly.
Did Chrysler ever put these smaller rotors on b bodies? Are they C body rotors? I did strip a 68 Chrysler 300 years ago. Maybe it’s from that car?
I’m open to possibilities here.
