Squeaking sound while driving

Coming from the rear wheels on a 2001 Subaru Outback. It goes for
about
one mile of driving and then stops. Brakes immediately come
to mind but why would it stop squeaking after about one mile of
driving?

2-3 things come to mind. Does the sound change when making a sweeping
turn? Which direction is better or worse? Sometimes a bad wheel
bearing will be indicated by the additional 'load' vectored onto when
taking a curve at speed.

Try to see if one wheel is hotter than the other after a coupla miles
of driving. If the brakes are 'stuck', it will heat the wheel up.

When was the last time the brakes were replaced? There is a squealer
(sound indicator) buitl onto the pads.

Well, if you live where i live and it's been RAINING FOR 45 DAYS! the
shoes can swell on the rear drum brakes and stick until they heat up a bit.

2000 OBs have rear disc brakes, and I'd expect the 2001s to have them too.

I was afraid of that...

Actually, as late as 1999 they have both, and I am fairly sure that
even through 2004 they have both. I know on my 95 and 98 Inside the
rear rotor there are drum brakes. This is the emergency brakes. Most
cars use the rear calipers for both the hydraulically actuated brakes,
and the cable actuated emergency brakes, but not Subaru. It's that
much safer to have a separate brake mechanism for the emergency brake.
So the emergency brakes are actually drum type brakes and the drum and
rotor are the same piece.

There is a small drum inside the disc for the E brake.

Driveshaft U joint would be a prime suspect, especially if the
squeaking cadence is faster than the rate the wheels turn.

One squeek per wheel revolution - brakes or Cv joint, etc

Multiple squeeks per wheel revolution = driveshaft.

Toyota does this on a lot of their all wheel disc models, too...

As did Alfa in the mid 1960's (105 series cars - I have 2)

I had all kinds of weird noises coming from my '97 Outback. Replaced the
brakes and rotors and all is well.

That said, if you have plenty of brake pad left, it could be just a
vibration in the pads. An easy fix is to pull the pads and apply a little
antisqueak lube to the "backs" of the pads and replace. I've done this on
numerous British cars to resolve similar noises. Certainly can't hurt
anything.
