You know a LOT more than SOME of the participants here...... One problem, however, is your use of anti-seize in place of lubricant. Most anti-seize compounds are designed to keep non-moving things from sticking together, NOT for lubrication of moving items. Some anti-seize compounds, those intended for oxygen sensors for example, contain glass beads. What sort of lubrication do you suppose glass beads provide? For drum brake shoe pads, there is "Brake Lube" - which is, simply, white lithium grease.

I did not know you could use it for where the shoes contact the backing plate. -- Tegger
