Frequent inhalation of brake pad dust,
regardless of material composition, could be hazardous to your
health.
•
|
Avoid breathing dust
particles. |
•
|
Never use an air hose or brush to clean
brake
assemblies. | |
1. |
Raise the rear of the vehicle and make sure it
is securely supported. Remove the rear
wheel. |
2. |
Release the parking
brake. |
3. |
Remove the brake hose (A) from the suspension
arm by removing the brake hose clip (B).
Thoroughly clean the outside of the caliper to
prevent dust and dirt from entering inside.
Support the caliper with a piece of wire so
that it does not hang from the brake hose.

|
4. |
Remove the two guide rods (C) and caliper (D)
from the bracket. |
5. |
Remove the pad shim (A) and brake pads
(B).

|
6. |
Using vernier calipers, measure the thickness
of each brake pad lining. Measurement does not include pad backing
plate (A) thickness.
Brake pad
thickness: Standard: 9 mm (0.35
in.) Service limit: 2 mm (0.08
in.)
|

|
7. |
Remove the pad retainers.

|
8. |
Clean the caliper thoroughly; remove any rust,
and check for grooves and cracks. |
9. |
Check the brake disc for damage and
cracks. |
10. |
Install the pad
retainers. |
11. |
Check the foreign material at the pad shim (A)
and the back of the pads (B).
Contaminated brake discs or pads reduce
stopping ability. Keep grease off the discs and pads.

|
12. |
Install the brake pads (B) and pad shim (A) on
the caliper bracket. Install the inner pad with its wear indicator
(C) facing down ward.
If you are reusing the pads, always reinstall
the brake pads in their original positions to prevent a momentary
loss of braking efficiency. |
13. |
Rotate the caliper piston (A) clockwise into
the cylinder, the align the cutout (B) in the piston with the tab
(C) on the inner pad by turning the piston back. Lubricate the boot
with rubber grease to avoid twisting the piston boot. If the piston
boot is twisted, back it out so it is positioned
properly.

|
14. |
Install the brake caliper
(D). |
15. |
Install and torque the guide rods (E) to
proper specification. |
16. |
Install the brake hose (F) onto the suspension
arm with the brake hose clip (G). |
17. |
After installation, check for leaks at hose
and line joints and connections, and retighten if
necessary. |
18. |
Depress the brake pedal several times to make
sure the brakes work, then test-drive.
Engagement of the brake may require a
greater pedal stroke immediately after the brake pads have
been replaced as a set.Several applications of the brake pedal
will restore the normal pedal
stroke. | |
Runout
1. |
Raise the rear or the vehicle, and make sure
it is securely supported. |
2. |
Remove the brake
pads. |
3. |
Inspect the disc surface for damage and cracks
clean the disc thoroughly and remove all
rust. |
4. |
Use wheel nuts and suitable flat washers (A)
to hold the disc securely against the hub, then mount a dial
indicator (B) as shown, and measure the runout at 10 mm (0.4 in.)
from the outer edge of the disc.

|
5. |
If the disc is beyond the service limit,
refinish the brake disc.
A new disc should be refinished if its
runout is greater than 0.10 mm (0.004
in.) | |
Thickness and parallelism
1. |
Loosen the rear wheel nuts slightly, then
raise the vehicle, and make sure it is securely
supported.
Remove the rear
wheels. |
2. |
Remove the brake
pads. |
3. |
Using a micrometer (A), measure disc thickness
at eight points, approximately 45 apart and 10 mm (0.4 in.) in from
the outer edge of the disc. Replace the brake disc if the smallest
measurement is less than the max. refinishing limit.
Brake disc
thickness: Standard: 10 mm (0.4
in.) Max. Refinishing limit: 8.0 mm
(0.315 in.) Brake disc parallelism:
Max. 0.015 mm (0.0006 in.)
|
This is the maximum allowable difference
between the thickness measurements.

|
4. |
If the disc is beyond the service limit for
parallelism, refinish the brake disc.
If the brake disc is beyond the service
limit for refinishing, replace it (see DS group-rear
axle). | |
