I guess I've never had shoes so well contoured to the drum that I can get away
with three. If I adjust the clearance to the point where three will work, the
shoes drag too much.

Subject: Re: [Roadsters] braking issue
I have always used three clicks. There are several locations to adjust
parking brake linkages, The big player is the pivot point on the back axle. It
is a little three armed thing. Take it apart and clean out all the old dead
grease and lube it properly so it moves freely. The arm that the link to the
parking brake lever goes to should be angled toward the rear of the car. If
the links to the wheel brakes are too long and it is pointing towards the
front you will run out of travel and pulling harder on the lever will get you
nothing. With the parking brake off the lever going to the parking brake
handle should be pointing toward the rear of the car. Not straight back but
toward the rear. With the brake engaged it should be pointing toward the side
or a little forward. Maximum leverages is obtained when the lever is straight
sideways. This is your three click point. Once the linkage is set up you will
not need to mess with it again for a long time. As the parking brake lever
increases in the number of clicks you will also get more petal travel. When I
get to about 5 clicks I tighten the shoes to return it to three clicks and the
petal travel is reduced. If the links from the pivot to the wheels are too
long you just can not set up the brakes properly. You can get three clicks by
shortening the adjustment in the pivot to parking brake lever cable but the
pivot geometry will be wrong and the parking brake will not work very well.
Based on my observations, I would bet that most roadsters would benefit
greatly from having the parking brake linkages properly lubed and adjusted.
