Forum;

Derek has it absolutely right!...and the steel adjuster pins frozen in the alu Adjuster housing is the typical failure mode...so even if, by some small miracle, the threads (steel) of the adjustment cone (also in the alu housing) were loose you were able to turn it to back it out, that doesn't mean the pins are going to be free to move back and allow Brake Shoes to retract.

IMO, forget about the messing around with Adjusters when removing Drums! After Drum is removed, Ajusters should be checked, disassembled, cleaned of aluminum oxides, treated with graphite filled grease, as part of a proper brake service!

Even BRAND NEW adjusters should be disassembled and rebuilt with Graphite filled grease to prevent galvanic seizing!

Cheers
