Get more wear out of the shoes that way! :thumbsup2:
 
Those companies that do those brake jobs won’t last long, they will go down hill fast.

Who is doing all these "brake" jobs?

Out of curiosity.. I am trying to figure out how this is even possible.. not that I have take apart huge numbers of brakes but... every drum brake I have taken apart has for obvious reasons had a backplate and the mechanism was mounted onto the backplate. there is a linkage between the pads that they seem centered so something must be holding them in place? Maybe just overthinking and someone is just messing with us.

Actually, it's a large truck brake setup that is activated by an external air cylinder and lever. A little confusing if someone has never worked on one of these setups. I've actually seen some without back plates, usually on an old trailer! The cylinders are spring loaded and air pressure holds them off. A safety brake system, if air pressure drops below a set pressure, the brakes will automatically lock up. It's a pain to get them to release by relieving the spring pressure. PJ

Thanks Paul now it makes sense so this is also missing the actuator. Probably on trailer like you suggested.
 
The actuator would be on the side opposite the pivot point and spring. But there's still no drum in that photo for the shoes to act on.
