Installation
WARNING: Ensure brake pads are installed with lin-
ings facing rotor. Failure to do this will cause poor per-
formance and damage to equipment and may result in
injury.
1. Check brake pad backing plate notches for burrs or excess
coating and ensure that the pad will fit the adapter slide
with enough clearance to afford stick-free movement.
CAUTION: Remove any excess lubricant that may have
squeezed out from between mating surfaces. Do not allow any
lubricant to come in contact with brake pad friction material
or brake rotor surfaces.
2. Lubricate caliper guide pins, sleeves and adapter slides
®
with Permatex Ultra Disc Brake Caliper Lube prior to
installation.
NOTE: Always apply thread-locking compound to the tapped
holes.
3. Apply thread-locking compound to tapped holes of
adapter.
4. Using special tool J–42553, rotate caliper piston in a
clockwise direction, and at the same time apply force on
outer piston face until caliper piston is seated in piston
bore (Figure 7-20).
5. Position caliper and yoke on adapter and rotor. Secure
yoke to adapter with two washers and capscrews. Using a
crowsfoot, tighten capscrews to 40 lb-ft (54 N•m)
(Figure 7-19).
6. Install parking brake cable to caliper cable bracket and
secure with clip (Figure 7-21).

mance will result.
