Thank you TRK Guy for starting a discussion!!
The emergency brake cable is kind of a separate mechanism from the hydraulic system and the self adjuster mechanism. If your emergency brake cable is engaged, it mechanically forces your brake shoes outward, meaning they are locked down.
If your emergency brake is stuck in the applied position, there are very few options you have to make it release. Sometimes you even have to break or cut the brake drum off. My cable was sticking and that’s all I had to deal with. Luckily I was able to knock it loose. Drilling a hole in the drum was my fix and I have never seen that mentioned before so I thought I would post it.
