As a follow up to my issue with the rear drum rotor, I bought a new
rotor and rear e-brake shoes.

However, when I took the existing shoes off, it seems that I was given
the wrong part. The current rear shoes look to have (forgive my
terminology if it is wrong), the wheel cylinder attached as part of
the shoe. By "wheel cylinder," I mean that there is what looks like a
cylinder with a "star" that encircles the cylinder which I believe is
used to adjust the shoe.

I didn't see a way to disconnect the cylinder ends from each shoe and
I didn't see a comparable notch in the new shoes for the cylinder to
fit.

Am I correct that it is a "wheel cylinder"?

Is there a special designation that I need to use when buying the
shoes so I can get the correct type?

The rotor replacement went well, except for the fact that I only have
one e-brake shoe on that side until I can get the correct parts.

Thank you,
Dave

Your description doesn't quite fit the picture which I have in the parts
list on VADIS. [If your email address is genuine and you would like a copy,
please indicate and I will email it to you].

As far as I can see, the AWD rear brakes are similar to those on FWD V70s -
in that there is a combined disc (rotor) and drum - using the disc with
hydraulically operated pads for stopping and using the drum with
mechanically operated shoes for parking. Is yours not like that?

If it is, the parking bit should have an expander at the bottom - which
pushes the shoes apart when you operate the handbrake, and an adjuster at
the top - which you operate by poking a screwdriver through a hole in the
drum in order to turn a star-wheel. There's no hydraulic cylinder, as such.
The adjuster and expander both have slots in each end which fit over the web
of the shoes - so there's nothing other than the linings permanently
attached to the shoes.

If yours are somehow different, could you take a digital photo of the brake
assembly with the disc/drum removed and upload it somewhere and post a link
to it here. Hopefully someone will then know what's going on!

Roger,
Yes, you can send the picture to my email address, it is valid and I
will look for it. The brakes are as you describe, the combination of
disc eganged via a piston and the mechanical shoes.

The terms 'adjuster' and 'expander' seem to be more accurate than how
I phrased it, as the two pieces fit together and there did not seem to
be anything more to it.

The pictures may give me a better idea of what is there. However, the
two components on either shoe didn't seem likely to disconnect from
the each shoe itself...and at the time, I did not want to force
anything if I was going to have to put the old components back on.

TIA,
Dave

It's on its way to you.

I think you'll find that the slots in the ends of the expander and adjuster
just push onto the shoes. If they don't want to come off, they may simply be
rusted on, and you may need to use a bit more 'urge'.

Roger,
I replied to your email and sent you a picture of what I see attached
the brakes.

Thank you,
Dave

When did you send it? It doesn't seem to have arrived yet. [I received your
earlier reply, immediately after I sent you the parts list].

Roger,
I sent it yesterday (6/16). When I did a "reply," I noticed that the
address changed from one address to the another. I won't print the
full addresses here, but the first started as watt.(removed) and the
second was news(removed). I resent the email to both addresses this
morning, 6/17.

I read your reply, and will need to disassemble the wheel again to
confirm, but your observation is what I was looking for...I don't mind
working to separate the pieces if that is what is necessary, but since
I was unfamiliar with what it should look like, I was hesitant to take
that step.

Thank you for your replies and insight.

Dave

Good luck with getting it apart - but they are definitely separate
components.

Yes, that's intentional. I use a (disposable) Googlemail address for
newsgroup purposes, but don't monitor Googlemail very often because I don't
really expect many personal emails from Usenet users.

When I reply in Outlook to an email received by the Googlemail address, it
goes out with an entirely different return address which *is* monitored
regularly.
