Cleaning and Inspecting
1. Inspect the brake pistons for gouges, cracks, pitting,
scuffing, or corrosion. If any of these conditions
exist, replace the piston.
 NOTE: The inner and outer caliper housings are not
serviceable components. If either or both are defec-
tive or damaged, the complete caliper assembly must
be replaced.
2. Clean the piston outer surface by using a soft Scotch-
Brite pad and clean brake fluid as a cleaner.
CAUTION
Do not use any sharp cleaning tool on the piston sur-
face or in the O-ring groove as it may cause damage.
3. Inspect the piston bore of the inner and outer brake
calipers for gouges, cracks, pitting, scuffing, or cor-
rosion. If any of these conditions exist, replace the
caliper.
4. Clean the caliper inner wall surface using a soft lint-
free cloth and clean brake fluid.
CAUTION
Care must be taken not to allow any contaminants into
the fluid passages of the calipers or brake system
malfunction may occur.
5. Inspect the condition of the brake pads. Replace if
damaged or worn. The brake pad thickness must be
greater than 0.20 in. If the brake pad thickness is less
than specified, replacement of both pads is neces-
sary.
6. Inspect the brake hose for cracks and deterioration
and check the condition of the threaded connectors.
Assembling/Installing
1. Apply approved brake fluid to new O-rings; then
install the O-rings into the groove of each caliper
half.
CAUTION
Never reuse piston O-rings. Always install new O-
rings when installing pistons in the brake caliper.
2. In each caliper half, apply approved brake fluid to
the brake piston; then while twisting, install the pis-
ton with the dished side facing out.

 NOTE: To aid in installing the piston, make sure the
piston O-ring is properly seated in the groove of the
caliper housing.
3. Using a suitable press, install a new inner bearing
into the caliper housing until it is properly seated.
When installing a bearing, always press on the outer
race of the bearing.
4. Install the snap ring securing the bearing in the cali-
per housing.
5. Place the inner caliper housing/driveshaft bearing
housing onto the driveshaft and secure with the cap
screws coated with blue Loctite #243. Tighten to 25
ft-lb.
6. Apply Anti-Seize Thread Compound to the splines
of the brake disc; then install on the driveshaft and
secure with the retaining ring.
7. Install a new seal in the outer caliper fluid passage;
them install the outer caliper and secure with the cap
screws. Tighten to 25 ft-lb.
