Even though it’s rusty and is still holding Scottish air inside the wheel is just sliding along the ground now. Likely occurred after using the brake pedal (which by the way is on the left foot and not the right foot like Canadian motorcycles :o) ). My guess is that something has seized in the old drum brakes and so this is a must to repair for the first phase.
Turns out it was 50 years of cleaning required, but removal of the pin was the hard part.
The above was me using my heat gun to help loosen the pin so that I could turn it… still took quite some time and some persuasion to get it moving incrementally until it finally was able to be removed.
After re-assembly the brake drums were properly being expanded to engage and stop the wheel. The pads seemed fine and so just a general clean up so that the bike is workable for now.
