GT6: Adjust self-adjusting brakes?

[msecres@ibm.net]

I'm in the process of rebuilding the rear brakes on my GT6.

They have the curious self-adjusting mechanism -- a geared spindle on 
the butt end of the cylinder, coupled to the handbrake via a lever.  As 
the handbrake is activated, it seems the gear moves to position the 
shoes.  Does anyone have experience with this?  As I am ready to install 
new cylinders, etc., I am wondering how the initial setup is made on this 
mechanism ...

Wondering in Washington ... (D.C.)
