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.

I never heard that about the number of notches for the parking brake. I
will
check mine.
