You should search around for some pics/tutorials on care/maintenance for
your Soob. maybe buy a Chiltons or haynes Manual too. You can do a lot
yourself, but having some guidance or, better yet, inviting an
experienced buddy over to help will prevent a lot of major mistakes.

Search around at www.scoobymods.com/ , www.ultimatesubaru.org ,
www.nasioc.com , and (maybe) www.endwrench.com

be careful!

Thanks Bob. Doing my own work on all my bikes is what gave me the
confidence to step up to the car!

Just to clarify, I can get the axle nuts off no problem. I just
didn't use as much "persuasion" as possible on the drums because I
didn't think I had the right replacement part.

I have a buddy who has shown me a few things and has the tools
necessary. We removed the rubber plug on the back, but I think we
removed the wrong one. The chilton's guide I have showed the plug
near the bottom, but we tried the top one at first. Like I said, we
didn't pursue it because we thought we had the wrong replacement
drums. The brakes are off, the wheels are spinning freely.

The Chilton's info is good, but I find it is a rough guide only. You
need somebody experienced handy to deal with snags. "Remove drums" is
not all that useful of an instruction when you don't know that the
drum is seized to the flange.

We will try again on Monday, and we might start with the front first
just to see what those flanges look like.

Thanks all.

Release the parking brake.

The rubber plug is nearer the top. A screw driver or something like it is
pushed in and it causes the automatic adjuster to release. It will be easier
to understand once you get one off.
If you don't release the automatic adjuster, the shoes might hang up on the
lip of the inside of the drum if there is one.

A trick I learned is not to take the tire off. This makes it easier to
remove the axle nut and gives you more leverage to monkey with the brake
drum. Rap things with a big hammer a couple of times and things might loosen
up for you.
Leaving the tire on the drums also makes it easier to tighten the axle nuts
when you put them back on.

I replaced all 4 corners today.

I started with the drums again. This time, knowing what the parts
looked like, and armed with 8mm bolts, I was confident. Things didn't
start well. One of the two bolt holes in the drums quickly stripped
and became useless. However, it didn't take long for the other bolt
to snap the drums loose. Beauty. In fact, the outside part of the
drum broke right off. See pic:

http://www.geocities.com/chicobiker/brake_drum003_sm.jpg

Those with a sharp eye will notice the rust on the break. At least
2/3rds of that break was old. The funny thing is that the car passed
an Ontario Safety Standards test just yesterday. Hmmm ...

Anyway, It didn't take too long to put the new ones back together. I
now see the adjuster, and can see how easy it would be to adjust from
the outside.

Drum #2 came off even easier (with the 8mm bolts of course).

Rotor #1 came off pretty easy. The bolts holding the brake pad
housing were very hard coming out, but came out. At this point, we
broke for lunch. When we came back from lunch, we set about the task
of putting the new pads in the housing. Uh oh. They are not the
right pads. A quick trip to the parts store for some compatible
pads. I had to settle with Munroe pads in order to get the job done.
Once we returned to the job, I set about putting the brake pad housing
back on the wheel hub. I put too much force on the bolt and broke it.

<sigh> The job had been going so well, and now it was turning sour.
Thankfully, it was very easy to remove the remainder of the offending
bolt. The brake pad housing could be put in a vise and the remaining
bolt was sticking out enough for vise-grips. Now came the hard part
of finding a replacement. An auto-parts dealer didn't have anything,
two japanese car dealers had nothing, and finally canadian tire had
some lower grade bolts. We weren't happy with that for the important
job of holding the brakes on, so we called the nearest Subaru
dealership. It was only 20minutes drive away, and they had the bolts,
so off we went. About 3 hours after the broken bolt, we were back in
business.

Putting that corner together went fine after that. I used a torque
wrench earlier in the process this time!

The 2nd rotor was up next. Getting the caliper off was no trouble. I
put in the 8mm bolts in the rotors and started cranking. I thought
bolt number felt a little soft. I went to bolt #2 and it broke. I
extracted bolt #1 and it was bent. I put in a 3rd bolt and it
eventually broke. Same quality bolts as I was contemplating for the
opposite side caliper. Glad I didn't use them! Torch and persuasion
hammer and that corner came out.

Brakes feel great now. Even with the challenges of the job, I don't
think it was particularly complicated, and well within my abilities
for the future. I certainly would give myself a whole day though. A
simple thing like a broken bolt sure adds hours to a job pretty
quickly!

Good job! And an important reminder for us all; bolts ain't bolts .
Use proper high-tensile or high-shear bolts where they're called-for...
