Hello, I have recently replaced the rear disks, pads, and parking brake shoes on my e250 the install was pretty straightforward and all has been fine braking wise. I adjusted the new parking brake shoes to the same number of turns on each side using the adjustment screw. One side was getting very hot after a quick test so I backed that side off fully and retested, I obviously lost any sort of parking brake function doing this but the temp on the disk was normal. I've now adjusted this to a happy medium of far enough away to give the minimal amount of rubbing but also giving a decent parking brake with around 4 to 5 clicks of the pedal.
Now the disk seems to still be rubbing slightly but the temp is still higher than the other side.
Has anyone had this happen before ? Will it settle down over time as the new pads wear, its a very light rubbing for less than a quarter of a turn of the rear wheel.
I've checked the fitment of the new shoes again and cannot see any difference to the otherside.
My only thought now is to maybe swap the disks over to see if they rub against the other disk or if the problem moves to the other side.

Sounds like you've done everything by the book.
Can you take pictures showing those calipers in question? floating/fixed...
Also how did you lubricate those brakes ? What lube?
A little rubbing when new is normal until all surfaces mate to each other ... 150 miles.

The parking brake is a primitive design, mild rubbing seems inevitable and when the new thick parking brake shoe touched no more, you can smile.
Also one can not expect drum based parking brake to work IMMEDIATE GRIP like a disc brake, it does not work that way. It needs like 1/2 tire revolution to produce the SERVO EFFECT.
The first link you sent has a YouTube video of the parking brake rubbing, exactly how mine is behaving.
I wonder if they were also experiencing higher temp on the disk/hub as a result once going for a drive.
It's a pretty bad design in my opinion, the idea of removing the assembly entirely sounds good to me, however here in the UK the parking brake is needed for the MOT test.
I will continue to run the car with it slightly rubbing, in a hope that it wears down to such a degree that it goes away. If not then I will have to adjust it to zero on the screw and live without the brake until MOT time, at which point I can adjust it back in to pass.

It's pretty standard here too that the parking brake should work, but lots of times the people doing the inspections are lazy and do it really quick. According to the state, a proper inspection is supposed to take 45 minutes and I've never been to a place that took more than 10 minutes, did see a guy jack up the front once to check wheel bearings/ball joints but they hardly ever do that. I think the station keeps $23.50 of the $35 inspection fee so they'd lose money if they did it right.
