Hi Sidders did you try adjusting the angle of the shoes with the bolts in the backplate Phil

Hi Elv..they are bolted up tight to the backplate...i'm sure its the lining width that is fouling the drum once its held in tight with the holding screws.
I thought I'd ask mate, as the nuts should be done up just enough so that the actuators/expanders are still free to move on the backplate. This allows for an equalizing of braking effort of both shoes against the drum, call it self centering if you will.

Neil is right in what he says but what about the packer plate between the back plate and the actuator? has your problem side got one? if not it will be your problem as everything will be out of line. The face between the actuator and packer plate should be greased, I used copper slip but the original grease when I first stripped everything down seemed to be white? but had gone hard and crystalline.
For what its worth, I have never had an issue with mine since I rebuilt it, the nuts securing the actuators are off tight so that the teardrop washers do not to distort the rubber boot base, that is the guide I used.
Hope this helps.

Hiya Bob! :D ,

Good point about the packers/spacers behind the expanders and adjusters mate. if one is missing the shoes will be angled slightly in relation the the drum, which may cause the shoe to rub on the drum, the slight angling of the shoe may also be enough to cause an expander or adjuster plunger to stick in it's housing.
