Passenger side rear e-brake shoe rubs against the (lack of better terminology) wheel hub that it is backed up against. I am positive the squeaking is coming from the e-brake shoe because I can recreate the noise by wiggling it (after disassembling the rotor and caliper of course). Is anybody familiar with a fix for this? I put stop-squeal grease but that only helped for 3 minutes of driving.

 

are you adjusting it correctly? i believe those use star adjusters like most other drum brake setups...

 

Maybe that adjuster is broken and needs to be replaced? It seems loose at its tightest setting.
