Front Brake Pads
Inspection and Replacement
NOTE: There are two types of front brake calipers:
The caliper types can be identified by the "5410" or"2056" stamped on the caliper body as shown below.
Check the type of the brake caliper before servicing.
5i110 Type:
NOTE: For 2056 type disassembly procedures. see page
19-'10.
Never use an air hose or dry brush lo clean brake
assgmblios.
Use an OSHA approved vacuum cleaner to avoid
breathing brake dust.
Loosen the front wheel nuts slightly, then raise the
vehicle, and support it on safety stands. Remove
the front wheels.
Remove the brake hose bracket from the knuckle.
Remove the caliper bolt, and pivot the caliper up
out of the wav.

4. Remove the pad shim. pad retainers, and pads.
NOTE: When the caliper is equipped with an outer
pad shim, replace the shim together with the pads
5. Using vernier calipers, measure the thickness of
each brake pad lining. The measurement does not
include the pad backing plate thickness.
Brake Pad Thickno$:
Standard: 9.5 - 10.5 mm 10.37 - 0.41 in)

check for grooves and cracks.
8. Check the brake disc for damage and cracks.

10. Apply grease to the points indicated by the arrows
in the following illustration:
NOTE: Use the pad grease included in the pad set
or Molykote Nl77 grease, and apply a thin coat of
grease evenly to the designated points.

. Whon reusing the pads, always reinstall the
brake pads in their original positions to prevont
loss of braking efticiency.

ping ability. Keep grease oft the discs and pads'
NOTE: lnstall the Dad with the wear indicator on

'12. Push in the piston so that the caliper will fitoverthe
pads, Make sure that the piston boot is in position
to prevent damaging it when pivoting the caliper
down.
Pivot the caliper down into position, then install the
caliper bolt and tighten it.
CAUTION: Be caretul not damage the pin boot
when pivoting the caliper dowr.
lnstall the brake hose bracket on the knuckle
NOTE: Inspect the brake hose for interference or
twisting.
Depress the brake pedal several times to make sure
the brakes work. then test-drive.
NOTE: Engagement of the brake may require a
greater pedal stroke immediately after the brake
pads have been replaced as a set. Several applica-
tions of the brake pedal will restore the normal
Dedal stroke.
After installation. check for leaks at hose and line
joints or connections, and retighten if necessary.
