Ah ok. I was focused on the 10mm gap between the shoe and piston (as per your original post) Hence my suggestions regarding assembly of brake parts. And Mike and Jake make a good point. And yes. That was interesting to see the adjuster at work. Maybe next time my drums are off I'll have someone watch to see that mine are working right. (likely they are though) Best of luck! :) Neil.
