95 Legacy brake problems

Hello all- I've been having strange (possibly unrelated) brake problems on my 95 Legacy and haven't come across anything real similar in this group, so i thought i'd create a post.

1) Brake proportioning seems off - my rear brakes have always done almost all the work it seems. I haven't needed to change front pads in a few years / ~30,000 miles, while the rears wear much quicker. Also confirmed by the amount of brake dust on wheels!

2) After having a pad rubbing problem on left rear caliper, (very uneven pad wear / audible rubbing noise) i replaced both rear calipers and rotors using parts from Autozone last year. This fixed the problem for a while, until I noticed yesterday that it looks like i now have a sticky left rear pad/caliper AGAIN! I heard faint high pithced noise that went away when I touched the brakes, and the wheel and bearing were very hot to the touch when I pulled over. I found that if I punched the brake pedal just right while driving it would release the pad on some trips (wheel was cool to touch after stopping) but not others. Seems like a sticky piston, but these are NEW calipers! I should mention that the left rear rotor is slightly warped, but not outside of specification (.003").

anyone have any ideas? could these problems both stem from a bad proportioning valve? did I just buy crappy calipers?

Incidentally i called the local Subaru dealer a while ago and he had no helpful information (not surprising). said that he never heard of proportioning valves going bad.

Well, that's interesting. My brakes needed replacing and it was the left rear that had worn down the worst. Then the ABS light kept coming on but that's another post.
