Does your car have rear drum brakes or rear disc?
It has drum brakes.
Ok it sounds to me that the noise is probably the brake shoes moving a slight bit on entering or exiting. The way to tell would be to pull on the cable with the brake off and see if you can isolate it to one wheel. The brake shoes could possibly need deglazed and the spots on the backing plate were the shoes touch could need lubed. Or the parking brake cable may just me a little loose on one side and allowing the brake shoe to touch but fully hold.
