OK - thanks guys !!! Amazingly simple solution - disconnect the accessory battery... I can handle the rest.
BTW, I've started using "soft" pads, they actually smoothed out my grooved rotors on the '97 SL320, & don't make as much dust...
Brake just as well - I think...

Buy a punch set to hammer out the retaining pins which will have seized into the caliper. You may have to cut them. Have a new set ready to install as the old ones wont be worth saving.
I just remove the plug from the SBC ecu to disable SBC.

I have done this job twice. Pins were a nightmare twice and needed cut out. I am in the UK though so we have salt on the road. SBC disconnected twice and no issue. I appreciate this is perhaps not the correct procedure but Ive had no issues. I do now have STAR but have no issues with the brakes.
You could try to knock the pins pins out first to see if they are seized. Its the first part of the job anyway.

Yeah - I was thinking salt... I'm in Florida, so it's in the air - LOL... I looked at the pins, & they look pretty good, but no way to tell for sure till I have the wheels off - have found replacement pins on the site you recommended - Thanks !!!

Do not just disconnect SBC to replace your brakes! The system needs to re-calibrate to the new pads/rotors. My understanding is that the procedure I posted above will do this, but I can't promise that. I always just uses SDS and I know it does it. There's a guy on the other benz world that changed his brakes without deactivating and he ended up having to go to a shop with SDS to clear errors.
Looking at all of the posts here, it seems that just unplugging the battery does the job.
