INSPECTION
1. MEASURE PAD LINING THICKNESS
Using a ruler, measure the pad lining thickness.
Standard thickness: 9.5 mm (0.374 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: 32.0 mm (1.260 in.)
Minimum thickness: 30.0 mm (1.181 in.)
If the disc is scored or worn, or if its thickness is less than the
minimum, repair or replace the disc.
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: 0.15 mm (0.0059 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, confirm that the front hub bearing
play is within the specification.
4. IF NECESSARY, REPLACE DISC
(a) Remove the front axle hub (See page SA−7).
(b) Remove the disc from the axle hub.
(c) Install a new disc and torque the bolts. Torque: 74 N·m (750 kgf·cm, 54 ft·lbf)
(d) Install the axle hub and adjust the front bearing preload (See page SA−9 ).

BRAKE FRONT SPEED SENSOR
1996 LAND CRUISER (RM451U)
INSPECTION
1. INSPECT SPEED SENSOR
(a) Disconnect the speed sensor connector.
(b) Measure the resistance between terminals FR+ and FR −,
and FL+ and FL−.
Resistance: 0.5 − 1.6 kΩ
If resistance value is not specified, replace the sensor.
(c) Check there is no continuity between each terminal and sensor body.
If there is continuity, replace the sensor.
(d) Connect the speed sensor connector.
2. INSPECT SENSOR INSTALLATION
Check the sensor installation bolt is tightened properly and
there is no clearance between the sensor and axle end.
If not, tighten the bolt. Torque: 18 N·m (185 kgf·cm, 13 ft·lbf)
3. VISUALLY INSPECT SENSOR ROTOR SERRATIONS
(a) Remove the axle hub with disc (See page SA−67).
(b) Inspect the sensor rotor serrations for scratches, cracks,
warping or missing teeth.
(c) Install the axle hub with disc SA−9 ).
NOTICE:
To prevent damage to the serrations, do not strike the axle
hub.

TROUBLESHOOTING
PROBLEM SYMPTOMS TABLE
Use the table below to help you find the cause of the problem. The numbers \
indicate the priority of the likely
cause of the problem. Check each part in order. If necessary, replace these parts.
(w/ Differential locking system):
Check that center differential lock mode is set.
When switching differential Free↔Lock, the indicator lamp will blink if the gears of the differen-
tial lock sleeve are not meshed. If this occurs, when the tires are rotated \
to apply differential
power to the differential, the differential locks and the indicator lamp\
light up.
