[Roadsters] braking issue

Even if you go with five clicks the basic approach is the same, the  
geometry of the pivot has to be correct.

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.

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.
