a. Line up the serrations under the screw
head with the grooves in the backing
plate hole.
b. Draw the screw down with a nut and
washer by tightening the nut until the
screw head bottom is on the backing
plate.
c. Remove the nut washer.
8. Note wire routing on old magnet lever arm

(1-2) on the arm, leaving the clips in place.
Transfer these clips to the new lever arm,
making sure they are in the same position.
9. Remove the wire guide spring from the
magnet lever arm and the wires. Discard the
spring. (The wire guide spring is not needed
with the new style magnet lever arm.) (See
Figure 43).
10. Remove the magnet or magnets from the
used lever arm. Install the single, long-life
magnet in the same manner and location
on the new arm.
11. Route the magnet lead wires individually
through the five clips (1-2) on the arm.
Duplicate the wiring noted in Step 8 above.
(See Figure 44).
On right-hand brakes allow 2-3/8-inches of
wire between the magnet and the first clip.
(See Figure 45).
