Park Brake Adjustment
1. Stop engine and remove key. Release park
brake and measure the length of the spring. The
distance between the washer on each end of
the spring should be 2-7/8". FIG - 7
2. If adjustment is needed, loosen the nut below
the spring. Then rotate nut to desired position so
the proper distance between the washers is
obtained. Check other side for proper adjust-
ment.
3. Engage the brake lever and measure the
distance between the trunnion pin and the collar
welded to the brake rod. Distance should be 3/
16" to 1/4". FIG - 7

directly below the yoke. Using a wrench, rotate
the rod by turning the double nuts using the nuts
below the yoke and the nut you just loosened, to
obtain the 3/16" to 1/4" distance. Tighten nut
against yoke and check other side for proper
adjustment.
