Brake pills add how many degrees?

I believe the angle is 7 degrees forward of center.

Remove the brake rod, operate the lever by hand, add 2 0r 3 pills and check arm location, continue adding or removing 1 pill at a time until arm is correct.

When the correct angle is obtained, adjust brake rod length.

Les Andrews' section on service brake adjustment recommends 15° forward tilt on the actuating arm with all slack removed..... section 2 page 3

He first recommends a new 7 1/4" operating pin.

I used new pins and still had to add pills to get the 15° forward tilt.

yea i think the pins bouncing and vibrating act like a drill into the wedge. i have 2 pills on one side and 1 pill on the other to get ~15" tilt. straight up and down should be a firm lockup.
 
I adjust my front brakes so that when the arm is vertical the wedge just comes into contact with the wedge stud. When released the arm will find its position relative to degrees.
Once the arm is vertical any more movement past center gains no mechanical advantage.
When the arm is vertical the cam should be horizontal. Any movement past this point is a drop over center and will cause the pushrod to be pushed sideways and enough arm movement will cause the pushrod to bend.
Try this:
Without the shoes installed to get in the way, install the arm w/shaft/cam and the rod and the wedge on the stud with the stud tight. Hold the arm vertical and push the wedge to the end of its movement. The space between the end of the rod and the wedge socket is the space that needs to be filled. Too many pills is not a good idea as the socket becomes very shallow and the pushrod could become displaced.
 
I have one pill on one side and none on the other to achieve the 15 degree forward tilt.
 
Thanks all.
What I was looking for was the amount of degrees each would add.
So if I need 15 degrees and each pill adds 5 I'd put in 3.
Otherwise I will put in one, put the wheel back together, test it, take it apart, add another, put it back together, test it, etc.
 
If you need more than one then it is my belief that you need new parts. Either the operation wedge and or the operating rod are badly worn.
 
Differant idea, I cut an old brake rod to the the correct lenght plus a 1/4". Then ground it to fine tune the lenght. No pills needed
Just my W.A.G. at the problem
