Do you ever drive in reverse?
Where is the physical location of the star wheel when you observe the
worn out shoe? Has it ever opened all the way out or does it always
seem seized up or screwed in?
My rear brakes seem to wear out perfectly, but I have one good reverse
brake hit every morning getting out of my driveway which sets the
adjuster and prevents if from seizing up. I use antiseize on the
threads also.
The shoes ---- forward when you it the brakes going forward, then they
shift in a rotation when you hit the brakes in reverse which turns the
star wheel adjuster to set them up.
This also keeps the emergency brake handle 'at the same level' each time
it is used until the brakes are totally worn out, then the handle rises
fast. The emergency brake handle usually is a good test of the state of
the rear brakes.
The star wheels have a right and a left side. If these got mixed, you
can have the brakes always out of adjustment. It can happen easy. I
had a friend who was just looking at things while I was doing a brake
job swap mine on me once....
