REMOVAL AND INSTALLATION (Continued)
Then rotate caliper over rotor and seat notches at
upper end of shoes on mounting ledge.
(4) Coat caliper mounting bolts with GE 661 or
Dow 111 silicone grease. Then install and tighten
bolts to 10-20 N·m (7-15 ft. lbs.).
CAUTION: If new caliper bolts are being installed,
or if the original reason for repair was a drag/pull
condition, check caliper bolt length before proceed-
ing. If the bolts have a shank length greater than
67.6 mm (2.66 in.), they may contact the inboard
brakeshoe causing a partial apply condition. Refer
to Figure 14 for the required caliper bolt length.
(5) Position front brake hose clear of all chassis
components and tighten caliper fitting bolt to 31 N·m
(23 ft. lbs.).
CAUTION: Be sure the brake hose is not twisted or
kinked at any point. Also be sure the hose is clear
of all steering and suspension components. Loosen
and reposition the hose if necessary.
(6) Install wheel and tire assembly.
(7) Fill master cylinder and bleed brake system.

REMOVAL
(1) Raise vehicle and remove front wheel and tire
assemblies.
(2) Drain small amount of fluid from master cylin-
der front brake reservoir with suction gun.
(3) Bottom caliper piston in bore with C-clamp.
Position clamp screw on outboard brakeshoe and
clamp frame on rear of caliper. Typical C-clamp
attachment is shown in (Fig. 26). Do not allow
clamp screw to bear directly on outboard shoe
retainer spring. Use wood or metal spacer
between shoe and clamp screw if necessary.

(6) Remove outboard shoe by pressing one end of
shoe inward to disengage shoe lug. Then rotate shoe
upward until retainer spring clears caliper. Press
opposite end of shoe inward to disengage shoe lug
and rotate shoe up and out of caliper (Fig. 29).
(7) Remove inboard shoe. Grasp ends of shoe and
tilt shoe outward to release springs from caliper pis-
ton (Fig. 30). Then remove shoe from caliper.
NOTE: If original brakeshoes will be used, keep
them in sets (left and right); they are not inter-
changeable.
(8) Secure caliper to nearby suspension part with
wire. Do not allow brake hose to support caliper
weight.
(9) Wipe caliper off with shop rags or towels. Do
not use compressed air. Compressed air can
