Since this thread hasn't been moved yet, I'll reply here.

I've never worked on an Adenauer, but in those days, the Pontons and early Fintails used four-wheel ATE drums. Each front drum had twin single-ended wheel-cylinders with two leading shoes, Each rear used a single double-ended wheel cylinder with leading & trailing shoes. The cheapest models had manual adjusters via a bolt shoe-anchor through the backing-plate at the center of each shoe. The bolt had an eccentric plate that moved the shoe as the bolt was rotated.

Instead of the manual adjuster-bolt, the more expensive versions used automatic adjusters, via a fat shoe-anchor pin with a heavy spring and friction-washers. These had no normal provision for manual adjustment other that stepping on the brake-pedal.

If the friction-washers aren't worn out and allowing the shoes to slide too freely, it may be possible, to try what I did with my '60 Fintail. Before installing the drums, manually pry the shoes outward somewhat, with a screwdriver against the friction-washers, to effect a tighter adjustment.

Happy Motoring, Mark
