Yep, those are the ones I'm talking about.

Yep, they were easy.

Good point. I did have the handbrake set... DUH!! <Slap on forehead!!>

However, I don't think it will make a difference actually, but I'll make sure
not to have it set, when I try again. Why try again? Well, based on your
thought of whether the handbrake was set or not, I double-checked the Bentley.
It turns out that I was looking at how to replace the rear brakes on a
quattro, not the FWD model. DUH... AGAIN!! <Another slap on forehead!!>

I feel stupid now... but is it me... or are the d*mn Bentley manuals difficult
and a pain-in-the-arse to read? Where the diagrams/procedures are... it is not
too clearly defined whether it is a quattro or FWD they are talking about. I
know... I know... it is my own fault... I'm just venting frustration....

Well, looking at the PROPER diagram, I am supposed to remove the little clip
that holds the parking brake cable in place, and remove the cable. This would
make sense... as it has to be out-of-the-way in order to get at the two bolts.
I figured that, but looking at the diagram (albeit, the wrong one!!), it did
not say so. I feared going into uncharted territory, so I aborted the mission.

Hopefully, once I take the parking brake cable off it's mouting point, I won't
have a hard time putting it back together.... (anyone BTDT?)Oh well... as the
saying goes... "Light dawns on Marble Head" (in this case, it shines brightly
on my follicly-challenged skull!!"). Guess what I'll be trying again this
weekend?? I'll let you know if the operation is a success...

Oh, BTW, I noticed that one of the guide pins on the caliper was sticking...
it wouldn't glide back and forth rather easily. Can I just lube this
somehow... or does it mean that I need a new caliper?
