Hand Brake Pull Noise

[kk2002s]

First pull of the Emergency brake, while moving, produces a loud mechanical sound from the cables engaging. So the sound is local to under the glove box and rear wheels. It only happens that first pull of the drive. For the rest of the drive the hand brake works as expected. I'm thinking some type of self adjusting taking place. I don't typically set the Handbrake if parked on level ground. Especially in the winter or if rotors get wet. I do like to drag the rear brakes to clean the disks at the beginning of my drive. Anyone have thoughts on this noise. I don't think there is anything wrong just would like the comfort of knowing what is taking place.
