You are supposed to be able to access the starwheel adjuster through a hole in the brake disk to turn it with a screwdriver to cause the shoes of the e brake to move inward and provide enough clearance to pull the disk.

So says the book. I could not do it with my '95 E300D. I wound up just working the ebrake on and off hard a few times while driving and also braking hard and then pulling the wheel off asap with the disk still hot, and was able to work if off. It was a PITA, but it did come off.

Then even with the new disk and the shoes adjusted as far in as I could get, I still had a bit of rub on the new disk while driving. Squeak, squeak, squeak....

But it wore itself out after a few hundred miles of driving.
