I appreciate the advice and taking time to reply. Why would the completely new right rear drag and heat up with all new componenets? new metal slides were installed on the capliper braket with the pads, I ensured the pads could move as needed, no binding. The slider pins were cleaned and regreased before putting them back in. The caliper piston turned without issue to recede back into the caliper. As I mentioned the left rear was operating fine, with great pad wear, now it is dragging and heating up, not the right side. At the same time I replaced the right side, I pulled the pads on the left rear, made sure slider pins were good, everything was ok before putting everything back. This is massively frustrating compared to any other car i've owned. The brake mechanicals are the same components that have been around forever, why would it do this? The EBD electronic brakeforce distrubution system seems to me to be more of the culprit in this situtaion, but I can find very little information about it. It has the word "electronic" right in the acronym, so right away it makes me suspicious...i'm only 43 and already sounding like a old fart.
