Woohoo...today I finally got my parking brake problem solved. As AleX and MrVermin already knew, my stupid parking brake lever used to ratchet all the way up and not engage the shoes, so it was pretty much useless.
The other day I was able to track down the auto parking brake adjustment mechanism from a Ford dealer in the states. Parts arrived today and now I´m happy as can be.
The stupid teeth on the auto adjuster were all ground down for some reason which was why they weren´t biting at all.
