Snail's pace Blitz rebuild

[Ryan]

Was in the shed today in all the heat.
Working on the front brakes.
Replaced a brake shoe with a NOS one I had. The pic of the three brakes shoes shows the one I replaced, a NOS canadian one and a NOS USA one of a slightly different pad length. I used the canuck one.
The pic of the brake cylinder shows the shoe 'teeth', they spin, one is tighter than the other. I tried pumping air in to see them expand but to no avail, to much leakage. How do you get them out?
There was a fair bit of crap in the drivers side brake drum but nothing too bad. All cleaned up well.
