BRAKE PADS/SHOES - FRONT (Continued)
INSPECTION - DISC BRAKE SHOES
Visually inspect brake shoes (pads) for uneven lining
wear. Also inspect for excessive lining deterioration.
Check the clearance between the tips of the wear indi-
cators on the shoes (if equipped) and the brake rotors.
If a visual inspection does not adequately deter-
mine the condition of the lining, a physical check will
be necessary. To check the amount of lining wear,
remove the disc brake shoes from the calipers.
Measure each brake shoe. The combined brake
shoe and its lining material thickness should be mea-
sured at its thinnest point.
• For front disc brake shoes, when a set of brake
shoes are worn to a thickness of approximately 7.95
mm (5/16 inch), they should be replaced.
• For rear disc brake shoes, when a set of brake
shoes are worn to a thickness of approximately 7.0
mm (9/32 inch), they should be replaced.
• Typically, if front shoes are worn out, both fronts
and rears need to be replaced. Make sure to check rears.
Replace both disc brake shoes (inboard and out-
board) on each caliper. It is necessary to replace the
shoes on the opposite side of the vehicle as well as
the shoes failing inspection.
If the brake shoe assemblies do not require
replacement, be sure to reinstall the brake shoes in
the original position they were removed from.
INSTALLATION
INSTALLATION - FRONT DISC BRAKE SHOES
(1) Completely retract caliper piston back into pis-
ton bore of caliper assembly.
(2) Lubricate both steering knuckle abutments
with a liberal amount of Mopar Brake Grease For
Caliper Slides Lubricant, or equivalent.
(3) Remove the protective paper from the noise
suppression gasket on both the inner and outer brake
shoe assemblies (if equipped).
NOTE: The inboard and outboard brake shoes are
not common, refer to (Fig. 16) for inboard and out-
board brake shoe assembly identification.
NOTE: When installing inboard brake shoe into cal-
iper piston, be sure brake shoe is positioned
squarely against the face of the caliper piston.
(4) Install the new inboard brake shoe assembly
into the caliper piston by firmly pressing it into bore
of caliper piston with thumbs (Fig. 15).
(5) Slide the new outboard brake shoe assembly
onto the caliper assembly (Fig. 17).
(6) Install one rail shim on each machined abut-
ment where it will contact the brake shoes. Make

sure the alignment tabs on the shims are positioned
toward the abutments.
(7) Carefully position caliper and brake shoes over
rotor by reversing the removal procedure (Fig. 12).
CAUTION: When being installed, extreme caution
should be taken not to crossthread the caliper
guide pin bolts.
(8) Install the caliper guide pin bolts (Fig. 11). Tighten
guide pin bolts to a torque of 22 N·m (192 in. lbs.).
(9) Repeat the preceding steps on the opposite side
of the vehicle, installing the brake shoes on that side
of the vehicle.
(10) Install the wheel and tire assemblies.
