The right-side adjuster works just fine after installation of all (per the FSM, one operates the parking brake lever on the rear shoe to make sure the adjuster arm actuates the star wheel on the strut).
The left-side adjuster is the problem. Upon movement of the lever, the forward portion of the strut moves 4MM+ to the front, leaving a gap as indicated on the drawing.
This is because the shoes are held further apart on the left wheel than the right because of the different distance between the compressed piston stops, and the forward part of the strut moves to take up the distance. The shoes, etc., are identical.
Hence, the adjuster arm will not operate the star wheel. It will not move far enough "down" the wheel to move it.
I can get the adjuster to actuate the star wheel if I manually turn the star wheel to take up the 4MM difference (to then match its right-side sibling). Then, it works just fine. It is just that the left-side shoes are a little further apart than the right-side shoes. Mind, I still have to adust both sides further out to get the approved distance between the shoes and the drums.
Autozone says the difference in the wheel cylinders is an accepted variance...
Is this anything about which to be concerned? Or just button it up and forget about it? Am I just addled in my dotage?
The last drum brake work I did was on Morris Minors and a Singer, and these variances just did not crop up ('course, the Singer used mechanical brakes on the rear...and neither car had anything fancy like self-adjusting brakes).
Thanks.
