Using a screwdriver, remove the 4 cylinder boot set rings and
boots.
2. REMOVE PISTONS FROM CYLINDER
(a) Prepare the wooden plate to hold the pistons.
(b) Place the plate between the pistons and insert a pad at
one side.
(c) Use compressed air to remove the pistons alternately
from the cylinder.
CAUTION:
Do not place your fingers in front of the pistons when using
compressed air.

INSPECTION
1. MEASURE PAD LINING THICKNESS
Using a ruler, measure the pad lining thickness.
Standard thickness: 11.5 mm (0.453 in.)
Minimum thickness: 1.0 mm (0.039 in.)
Replace the pad if the thickness is less than the minimum (the
1.0 mm slit is no longer visible), or if it shows signs of uneven
wear.
2. MEASURE DISC THICKNESS
(a) Temporarily fasten the disc with 3 hub nuts.
(b) Using a micrometer, measure the disc thickness.
Standard thickness: 28.0 mm (1.102 in.)
Minimum thickness: 26.0 mm (1.024 in.)
Replace the disc if the thickness of the disc is at the minimum
or less. Replace the disc or grind it on a lathe if it is scored or
worn unevenly.
3. MEASURE DISC RUNOUT
Using a dial indicator, measure the disc runout at a position 10
mm (0.39 in.) from the outside edge.
Maximum disc runout: 0.07 mm (0.0028 in.)
If the runout is greater than the maximum, replace the disc or
grind it on a ºOn±Carº brake lathe.
HINT:
When the disc runout is outside the specified range, check the
front hub bearing in the same way.
4. IF NECESSARY, ADJUST DISC RUNOUT
(a) Remove the hub nuts and disc. Reinstall the disc 1/6 of
a turn round from its original position on the hub. Install
and torque the hub nuts.
Torque: 110 N´m (1,150 kgf´cm, 83 ft´lbf)
(b) Remeasure the disc runout. Make a note of the runout
and the disc's position on the hub.
(c) Repeat (a) and (b) until the disc has been installed on the
4 remaining hub positions.

If the minimum runout recorded in (a) to (c) is less
than the maximum disc runout, install the disc in that
position.

If the minimum runout recorded in (a) to (c) is great-
er than the maximum disc runout, replace the disc
and repeat step 3.

REPLACEMENT
1. REMOVE REAR WHEEL
2. INSPECT PAD LINING THICKNESS
Check the pad thickness through the caliper inspection hole
and replace pads if not within the specification.
Minimum thickness: 1.0 mm (0.039 in.)
3. REMOVE BRAKE CALIPER
(a) Remove the 2 sliding pins.
(b) Remove the caliper and suspend it so the hose is not
stretched.
HINT:
Do not disconnect the flexible hose.
4. REMOVE 2 PADS WITH 2 ANTI±SQUEAL SHIMS
5. REMOVE 4 PAD SUPPORT PLATES
NOTICE:
The pad support plates can be used again provided that
they have sufficient rebound, no deformation, cracks or
wear, and have had all rust, dirt and foreign particles
cleaned off.
6. CHECK DISC THICKNESS AND RUNOUT
(See page BR±39)
7. INSTALL PAD SUPPORT PLATES
8. INSTALL NEW PADS
NOTICE:
When replacing worn pads, the anti±squeal shims must be
replaced together with the pads.
(a) Install the pad wear indicator plate on new inner pad.
(b) Install the anti±squeal shim on each pad.
(c) Install the inner pad with the pad wear indicator plate fac-
ing downward.
(d) Install outer pad.
NOTICE:
There should be no oil or grease adhering to the friction
surfaces of the pads or the disc.
9. INSTALL CALIPER
(a) Draw out a small amount of brake fluid from the reservoir.

(b) Press in the pistons with a hammer handle or an equiva-
lent.
HINT:
If the piston is difficult to push in, loosen the bleeder plug and
push in the piston while letting some fluid escape.
(c) Install the caliper carefully so the boot is not wedged.
(d) Apply lithium soap base glycol grease to the sliding pins
and install the 2 sliding pins.
