Default rear brake squeak 1995

When releasing the brake pedal there is a short squeak sound that seems to
come from the rear drums -- usually happens when in traffic with lots of
on and off braking. Always squeaks on the release, not when applying. Is
there a certain part that should be replaced, or just an overall
cleaning/lube? Also, rear drum pads have never been replaced in 11
yrs/165k -- is this normal?

If you haven't replaced the rear pads for that long, they're probably
grinded down to 0. Its definitely time to replace them.

=========================
Rear drum brakes can last a long time.
If you can lift the car, there's an inspection hole for the front brake
shoe.
Less than 1/16" friction material (1mm) requires replacement. Since the
front shoe is wedged into the brake drum when turning forward, it tends
to wear more quickly, so the inspection hole will be in the front on
both sides. There's a rubber plug you pry out first.
Chances are the brake shoes are worn very close to their limit but
brake shoes are longer than brake disk pads so they have more friction
material , and since most of the braking force is distributed to the
front of the car, the rear shoes last longer than front brakes.
If you never do any hard braking, it is possible the rear drum is
"glazed" with a hard surface which makes the brakes last even longer,
but reduces effectiveness under heavy loading.
There are six (6) locations on the backing plate that require
lubrication with high temperature grease when the brake linings are
replaced. The threaded adjuster should also be taken apart, cleaned and
new high temperature brake grease applied to the threads and the ends.
There are small bent over flanges at three points on the sides of each
brake shoe - ends and middle that contact the backing plate so if these
are dry that could be the squeaking you hear.
Brakes should only be cleaned with brake cleaner. You don't want to
breathe any of the brake dust.
Probably time to simply plan on replacing everything. You can also
replace the brake springs which can lose tension over time from heat
cycling.
Do check the brakes first. I have a 1994 Camry with 150,000 miles. Just
took apart the rear drum brakes last week. Don't know if they were
original. Used 400 grit emery paper to remove the glaze from the drums,
applied synthetic brake grease at all the points shown in the factory
repair manual and replaced the springs. There was plenty of friction
material left on the brake shoes though, and very little wear on the
brake drum. Springs actually seemed to have plenty of tension
remaining, so that would be optional. If the shoes are completely worn
down, then I would replace the springs because there have been more
cycles of heating and cooling of the brakes over their life.
