Disassembly (Fig. 18)
1. Remove two (2) caliper slide pins that secure brake
pads to the caliper assembly.
2. Slide brake pads with attached anti--rattle springs
from caliper.
3. Remove anti--rattle springs from brake pads.
4. Clean caliper components with brake cleaner.
Inspection
1. Check brake pads for uneven wear that might indic-
ate binding in the caliper assembly. Replace the brake
pads if the friction material is worn to less than 1/16" (1.6
mm). Also, if pads are contaminated with grease or oil,
they must be replaced.
2. Check that slide pins are not worn or damaged. Wear
on the pins will prevent smooth brake operation.
3. If caliper damage or wear exists, replace complete
brake caliper assembly as caliper components are not
available separately.
Assembly (Fig. 18)
1. If brake pads are being replaced, it will be necessary
to push the caliper piston back into the caliper bore be-
fore installing new pads:
A. Loosen lock nut on parking brake push rod and
then unscrew the push rod that threads into the
brake armature in the caliper (Fig. 19).
B. While loosening push rod, make sure that lock
nut remains loose on push rod. Also, periodically
push caliper piston back into caliper until there is suf-
ficient room in the caliper for the brake pads and
brake rotor.
C. Leave lock nut on push rod loose so that parking
brake can be adjusted after caliper installation.
2. Place brake pads with friction material positioned to-
ward brake rotor position. Then, install anti--rattle
springs to holes in brake pads.
3. Slide brake pads with attached anti--rattle springs in-
to caliper. Make sure that friction material on pads is to-
ward brake rotor location.
4. Secure brake pads to the caliper assembly with two
(2) caliper slide pins. Make sure that the slide pins are
inserted through the center of the anti--rattle springs.
Tighten pins from 30 to 35 ft- -lb (41 to 47 N- -m).
