I put the car back on the road a few weeks ago. It's been running fine, but no parking brake, of course. I finally got around to opening it up today to investigate and see what can be done.

The left side looked unremarkable other than the little activator lever was in a position that made me think it should already be in the activated position.

I next checked the hand lever and found that the cable for the right side had nothing holding it at the wheel, so took that side apart to investigate and found that the small two-part lever mechanism was half missing, the cable-end pin had fallen out, and the shoes, springs and spacer bar were completely missing from the car. So, I'm a long way from having a solution. I cannot imagine why the shop would ever consider returning a customer car in this condition.

If I want to restore this to operating condition, I'm going to need to replace these irreplaceable parts. If anyone has any ideas.
