I have replaced all brake hardware and hoses on all four corners. The brakes are adjusted well (maybe toward the loose side).
Emergency brake is adjusted also. All new fluid and system is bled. It brakes well with a slight pull to the right (maybe following road crown).
Problem is after a five to ten mile run the left rear brake drum is about 60°F hotter than the right rear or any other drum on the car.
Both front drums are around the same temperature between themselves.
Could it be a bad left rear wheel bearing?
When I pull in and out on the hub there is about 1/32" play.
When rotating the wheel by hand you can hear a bit of a "rumbling sound".
Possible cause: When I had new tires mounted and balanced the shop adjusted the brakes (unrequested} and had the left rear so
tight when I drove about five miles I had smoke. After everything cooled down I found I could barely rotate the wheel.
Maybe at that point the extreme heat generated by the brakes cooked the bearing(?).
I have since torn down the left rear and checked everything; it all seems in order except the hub play and noise.
I have hit both brake shoes and drum with 60 grit in a cross hatch pattern to address any glazing.
Another thought I had is that this extreme heat event somehow damaged the rear wheel cylinder?
As it stands; the wheel rotates freely with just a touch of drag. After a drive, same thing. Nothing seems jammed or seized.
I am looking for some collective wisdom here. I am greatly appreciative of any assistance.
