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.
