park brake clevis. The gap should measure 1/8” (3.2mm)

f) If necessary, loosen the inner flanged nut and turn the outer nut to obtain the
1/8” (3.2mm) gap. Re-tighten the inner flanged nut. See Figure 11
g) If park brake does not fully disengage when the lever is disengaged check the
brake rod linkage assembly. The assembly should measure 7-3/8” (18.7 cm)
from the center of the ball joint to the center of the lower end of the linkage rod.
See Figure 8.
FIGURE 12
h) If the linkage does not measure 7-3/8” (18.7 cm) or still does not disengage as
desired, remove the bolt that secures the ball joint to the brake lever and
loosen the jam nut next to the ball joint. Rotate the ball joint in half-turns
counter-clockwise until desired disengagement is obtained.
