Went looking for a "friendly mechanic" today but being Friday not even one was open. So I enlisted the help of my son and proceeded to fit the linings. Pictures below show the outcome of the morning's endeavours.

One set of brake shoes done Three to go

Close up of the back of the rivet neatly folded with the special punch

Close up of the front of the lining showing the head of the rivet.
This set is ready to go in. However, I still have the shock absorber of this side to work on. I guess I have my work cut out for me:)
