Parking brake dragging

[SRT_BluByU]

Seems like my right rear parking brake is dragging ever so slightly.. makes a light noise when turning corners. I can reproduce it easily. I checked the pads and there is 70% or so left compared to the new mopar pads in the box i bought thinking they had just hit some kind of wear indicators.

The noise does not go away when accelerating or braking using the brakes.. but goes away if i pull ever so slightly on the e-brake lever. Any thoughts on a solution?

Update 10/10/20:
I removed the RR parking brake caliper and pads and cleaned it real good. The slide pins were spotless but the antirattle clip pin was caked on mess. I cleaned and dressed it. Used a soft brush, some warm water, dawn, and cleaned the caliper and pads (including backing plates). Also made sure the outer caliper backing plate mating surface (machined surface) was perfectly clean. Screwed the caliper piston in a half. Turn, Reassembled, and test drove. Problem is gone (at least for now).

The pads that were on there did not need to be replaced. With 36k miles on them they were at 9.5mm (the new pads i had bought mic’ed out at 9.75mm). I use the parking brake everyday multiple times a day and looks like the problem they had with earlier generations vipers smoking the inner pad has been solved in gen v. Ill continue to use it with confidence.

Ho-e this helps someone else.
