(12) Inspect caliper piston for pitting, scratches, or
any physical damage. Replace piston if there is evi-
dence of scratches, pitting or physical damage.
CALIPER ASSEMBLY
CAUTION: Excessive vise pressure will cause bore
distortion and binding of piston.
(1) Clamp caliper in a vise (with protective caps
installed on jaws of vise).
(2) Dip new piston seal in clean brake fluid and
install in the groove of the caliper bore. Seal should
be positioned at one area in groove and gently
worked around the groove (Fig. 190), using only your
fingers until properly seated. NEVER USE AN OLD
PISTON SEAL. Be sure that fingers are clean and
seal is not twisted or rolled (Fig. 190).
(3) Coat new piston boot with clean brake fluid
leaving a generous amount inside boot.
(4) Position dust boot over piston after coating
with brake fluid.
CAUTION: Force must be applied to the piston uni-
formly to avoid cocking and binding of the piston in
the bore of the caliper.
(5) Install piston into caliper bore pushing it past
the piston seal until it bottoms in the caliper bore
(Fig. 191).
(6) Position dust boot into the counterbore of the
caliper assembly piston bore.

Install Guide Pin Bushings section in the caliper dis-
assembly section of this manual.
(9) Install brake pads. See Installing Brake Pads
in the Brake Pad Service Procedures section of this
manual.
(10) Before installing caliper assembly on vehicle,
inspect brake rotor. If any conditions as described in
Checking Brake Rotor for Runout and Thickness are
present the rotor, must be replaced or refaced. If the
rotor does not require any servicing, install caliper
assembly.
(11) Install brake hose onto caliper using banjo
bolt. Torque the brake hose to caliper assembly banjo
bolt to 33 N·m (24 ft. lbs.). New seal washers
