Dear Bob,
A shim, e.g. 0.010", is usually placed between the cam and the end of the brake shoes before turning in the lathe. When the the shoes have been turned to the same size as the brake drum, removal of the shims gives a running clearance.

When arcing the linings to the drums there is, I recall, a shim put between the shoe and the lever...what is the purpose of this shim, and what is it's thickness?
