I know self adjusters are activated by applying the brakes when backing. What would cause one to over adjust itself. Could shoes not arched correctly to the drums cause this? Inspection shows the lower half of the shoes seem to be doing most of the work.

Inspection also shows all springs and parts appear to be in text book perfect condition. I used a new spring kit when I replaced the rear end last year. The brakes have been fine until a few weeks ago when I noticed the rears were starting to do the majority of the stopping. No fluid leaks, no air in lines. I readjusted the rears and will be test driving shortly.

Thanks in advance!

It seems that even self-adjuster brakes need to be adjusted from time to time manually...an easy little remedy is to use your parking brake once in a while(even if you dont need to)...that seems to do the trick.

make sure the parking brake strut bar moves freely.
make sure the primary and secondary shoes aren't reversed.
make sure the shoes line up straight at the top pivot point and stay on the pivot when you rock them back and forth.
check your front brakes.

this type of adjuster wont over adjust. if it did, your car's brakes would lock up while driving, or at the very least get hot enough to smell, and you would not be able to get the drum off.

i think normal wear pattern is the bottom of the leading shoe, and the top of the trailing shoe.

If I didn't learn it from my my mentors, I learned it as a result.
