Hmmm... What happened to my reply yesterday. Maybe I was hallucinating. (I had just got back from being knocked out for an esophageal endoscopy. They told me I shouldn't make any important decisions. Who knew?
)
At any rate, your diagram is more than I've been able to find so far, so thanks!
We've only had to replace the rear pads once and didn't have to adjust the emergency brake at that time.
Some time ago, I looked around for pad-replacement instructions but didn't find much. I'll keep looking and maybe there'll be more hints.
