The brakes on the 98 seem very weak, compared to the 97. I think the master cylinder was leaking internally, so I changed it. Still the brakes are weak. No air in the system.
The power brake accumulator holds vacuum okay. I am out of ideas.
I took it to a local mechanic that maintains our postal carriers Subies. He is scratching his head too. He suggested I buy some Subaru pads, because maybe the PO put cheap Autozone pads on it. I have had it only a couple months. Been weak since I bought it.

some one suggested the check valve device? that is in between the front and rear brakes or something like that. i have not addressed it, i don't have a replacement part handy, the 96 lego donor car i have has a different smaller part. it would probably work, but i'm don't want to risk reducing the braking ability of my car more.
my next guess was old bad coroded rusted brake caliper on the front. i do have a set of outback calipers i can swap in, but i have not yet. i need to get my toyota running better so i still have a car if something goes wrong.
looking forward to other responses.

I think your problem is a bad caliper, you can get some brake hose clamps and check them or you can go to some place like Midas and have it checked.
I had a 98 postal subaru that I just could not get good brakes on, I had changed pads, shoes, master cyclinder and many other things. I gave up and went to Midas, it turned out to be the right front caliper, they can leak down without leaking fluild.

test your check valve in the vacuum hose to the master cylender
i hate to be a dummy, but i don't know what it looks like, where it's located or how to test it.
is it internal on the booster, or is the nipple? threaded into the intake manifold ? how do it test it. once i find it?
