REPLACEMENT
1. REMOVE FRONT WHEEL
2. INSPECT PAD LINING THICKNESS
Check the pad thickness and replace pads if not within specifi-
cation.
Minimum thickness: 1.0 mm (0.039 in.)
3. REMOVE THESE PARTS:
Clip
2 pins
Anti−rattle spring
2 pads
4 anti−squeal shims
NOTICE:
The anti−rattle spring 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.
4. CHECK DISC THICKNESS AND RUNOUT
(See page BR−36)
5. INSTALL NEW PADS
NOTICE:
When replacing worn pads, the anti−squeal shims must be
replaced together with the pads.
(a) Draw out a small amount of brake fluid from the reservoir.
(b) Press in the pistons with a hammer handle or equivalent.
HINT:
Always change the pad on one wheel at a time as there
is a possibility of the opposite piston flying out.
If the piston is difficult to push in, loosen the bleeder plug
and push in the piston while letting some brake fluid es-
cape.
(c) Install the 4 anti−squeal shims to new pads.
HINT:
Apply disc brake grease to the inner anti−squeal shims (See
page BR−24).

INSPECTION
1. MEASURE PAD LINING THICKNESS
Using a ruler, measure the pad lining thickness.
Standard thickness:
1 ton: 9.5 mm (0.374 in.)
Standard thickness:
0.5 ton: 11.0 mm (0.433 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
Using a micrometer, measure the disc thickness.
Standard thickness: 25.0 mm (0.984 in.)
Minimum thickness: 23.0 mm (0.906 in.)
Replace the disc if the thickness of the disc is at the minimum
thickness or less. Replace the disc or grind it on a lathe if it is
scored or is worn unevenly.
3. MEASURE DISC RUNOUT
Using a dial indicator, measure the disc runout 10 mm (0.39 in.)
from the outside edge of the disc.
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 ”On−Car” brake lathe.
HINT:
Before measuring the runout, check that the front hub bearing
play is within specification.
4. IF NECESSARY, REPLACE DISC
(a) Remove the torque plate from the knuckle.
(b) Remove the axle hub (See page SA−16).
(c) Remove the disc from the axle hub.
(d) Install a new disc. Torque the bolts.
Torque: 64 N·m (650 kgf·cm, 47 ft·lbf)
(e) Install the axle hub and adjust the front bearing preload
(See page SA−19).
(f) Install the torque plate onto the knuckle.
Torque: 108 N·m (1,100 kgf·cm, 80 ft·lbf)
