  Thanks, I haven’t really ever had to remove rotors before and still learning when it comes to working on my car. I always thought the parking brake was combined with either your disk or drum braking system and never knew that having a separate brake housing in the rear rotors was ever a thing.

I have no idea of how common it is from a percentage perspective but I know several manufacturers have a rear disc ( for the regular brakes ) and a drum ( for the parking brake ) combination set-up.
