The end of the Emergency brake cable that fits into the drum housing has a one way spring clip,, that pushes in,, then expands itself once seated firmly into the drum backing plate,(housing), to remove it simply place a small hose clamp onto the steel end,, tighten it up,, then start to remove it, once the clip slips past a little bit,,remove the clamp and pull the remainder out of the housing. It can be frustrating trying to remove it with pliers and usually results in damage to the spring clip. Dont axe me how I know this!
