Original cast iron small drum brake shoes are one piece. No instructions are given in Ford Service to 'break' them at the pivot hole, seems logical that many have busted there over the years of use. On install the Ford Service says only 'place a little grease around the cam and bolt'. So you have lube at each end of the circle brake shoe.
There were many types of aftermarket back then where steel bands lined with brake material were sold as being better than just cast iron shoe. These install similar to the cast iron ones, most use only one spring.
The 'two' piece cast iron with lining is the new reproduction, it is two pieces because the same casting is flipped for use as the upper or lower shoe,....I understand a better new reproduction is now on the market from Synders, haven't seen them but that will be nice to have. I like finding the old aftermarket steel band styles and re-lining them with Model A brake shoe material, you have to grind it narrow to mate with the narrow T shoe.
