Guys, thanks - very helpful info!

Planning to do this on my '95 W202 - new to me and only 48k, but has minimal maintenance records. Just replaced front pads and may end up doing the rears too.

Did not realize I could harm the ABS system - so plan to use the drip method.

Of the 30+ cars I've owned, it's one of the easiest to work on. And way over-engineered - heaviest brake units I've ever encountered on a vehicle. Not a bad thing!
