facing forward (on the side toward the
driver).
2. The caliper lever must also point to the
9:00 position or toward the driver. New
calipers may be shipped with this lever
located differently. If so, remove the cot
-
ter pin from the castle nut and remove
the nut. Remove the lever from the cam
spline and reassemble it so it points to
9:00. See figure 8-3.
8.9.3 Adjust Caliper
1. Tighten the castle nut to remove all
clearance between the pads and the disk
but not tight enough to force the pads
and disc together, ie, finger tight and no
pressure on the cam lever.
2. Next, back off the castle nut ½ turn (180
degrees) and then line up the closest
cotter pin hole with a slot in the castle
nut. Install the cotter pin and secure it.
8.9.4 Adjust the Parking Brake Lever
on Hydraulic Brake Systems,
Replace Parking Brake Cable
1. Adjust the calipers first without the park
brake cable clevis attached to the caliper
lever. See 8.9.3.
2. Connect the clevis at the upper end of
the cable to the button head pin on the
park brake lever if not already con
-
nected.
3. With the park brake lever released,
check that there is no cable slack at the
park brake lever end. This is indicated by
there being no space between the
crimped ferrule (on the cable core) and
the upper cable clevis (with lever fully re
-
leased). Only if necessary, make the fol
-
lowing adjustment. With the park brake
lever released, at the lower end of the
cable assembly, adjust the two jam nuts
of the cable housing to the transmission
mounting bracket or adjust the clevis at
the end of the cable core so the clevis pin
can be installed to the caliper lever with
-
out applying any up or down pressure on
the lever. Tighten all jam nuts after ad
-
justing.
4. When the park brake lever is released
the lever linkage will hit a stop and this
position is not adjustable. When the park
brake lever is applied, it must go “over
center” to lock in the applied position. It
should also be in approximately a verti
-
cal position. If the lever can not be pulled
to this position with 33 lb (147 N) or less
(hand force), the adjuster knob on the
end of the lever is too tight. If it pulls too
easily, the knob is too loose. This adjust
-
ment does not affect the cable adjust
-
ment at the lower end.
