through the five clips on the arm, duplicat-
ing the routing noted in Step 4. (See Figure
8).
On right-hand brakes allow 2-3/8-inches of
wire between the magnet and the first clip.
(See Figure 9).
On-left hand brakes allow 3-1/8-inches of
wire between the magnet and first clip.
(See Figure 10).
Allowing this much wire prevents strain on
the wire when the magnet is pulled out the
maximum distance.

onto the terminal posts (6-3) in the following
sequence.
a. Place one internal lockwasher over each
post.
b. Place one wire terminal over each post.
c. Place one internal nut (6-1) over each post
and tighten them to 30-40 in. lb. torque.
10. Close the shoe (2-1) that was spread to
expose the terminal, and install the anchor
pin plate (4-2).
11. Install the shoe return springs (4-1) using a
brake spring tool.
12. Check to be sure shoes expand and con-
tract properly and are in correct adjust-
ment.
13. Reassemble the drum and wheel. Make
sure wheel bearings and wheel nuts are
adjusted to axle manufacturer’s specifica-
tions.
