REMOVAL AND INSTALLATION (Continued)
(3) Connect rear brake hose to caliper. Use new
washers on hose fitting and tighten hose fitting bolt
to 24-38 N·m (216-336 in. lbs.).
(4) Check brake hose position before proceeding.
Verify that hose is not twisted, kinked, or touching
any suspension components.
CAUTION: Check caliper bolt length before pro-
ceeding (Fig. 37). If the bolts have a shank length
greater than 67.6 mm (2.66 in.), they will contact the
inboard brakeshoe causing a partial apply condi-
tion.

(5) Lubricate and install caliper mounting bolts.
Start bolts by hand then tighten bolts to 10-20 N·m
(7-15 ft. lbs.).

(2) Install brakeshoes in caliper.
(3) Install caliper over rotor and into mounting
bracket.
(4) Verify that brakeshoe lugs are properly seated
on caliper mounting bracket (Fig. 40). Be sure
springs on outboard shoes are also seated against
bracket.
(5) Verify hose must not be twisted or kinked.
(6) Lubricate and install caliper mounting bolts
and tighten to 10-20 N·m (7-15 ft. lbs.).
(7) Install wheel and tire assemblies.
(8) Turn ignition On and run HCU pump until it
