1996 LAND CRUISER (RM451U)
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 ).

Author: Date:
1996 LAND CRUISER (RM451U)
ON−VEHICLE INSPECTION
1. SET REAR AXLE LOAD
Rear axle load (include vehicle weight):
1,330 kg (2,932 lb)
2. INSTALL LSPV GAUGE (SST) AND BLEED AIR SST 09709−29018
3. RAISE FRONT BRAKE PRESSURE TO 7,845 kPa (80 kgf/cm
2, 1,138 psi) AND CHECK REAR BRAKE PRES-
SURE
Rear brake pressure:
5,984 ± 589 kPa (61 ± 6 kgf/cm
2, 869± 86 psi)
HINT:
The brake pedal should not be depressed twice and/or returned
while setting to the specified pressure. Read the value of rear
pressure 2 seconds a fter adjusting the specified fluid pressure.
4. IF NECESSARY, ADJUST FLUID PRESSURE
(a) Disconnect the No.2 shackle from the shackle bracket.
(b) Adjust the length of the No.2 shackle turning it. Low pressure − Lengthen A.
High pressure − Shorten A
Initial set: 90 mm (3.54 in.)
Adjusting range: 84 − 96 mm (3.31 − 3.78 in.)
HINT:
One turn of the No.2 shackle changes the fluid pressure by
about 98.1 kPa (1.0 kgf/cm
2, 14.2 psi).
(c) In event the pressure cannot be adjusted by No.2 shackle, raise or lower the valve body.
Low pressure − Lower
High pressure − Raise
(d) Torque the 2 nuts. Torque: 13 N·m (130 kgf·cm, 9 ft·lbf)
(e) Adjust the length of the No.2 shackle again.
If it cannot be adjusted, inspect the valve housing.

BRAKE LOAD SENSING PROPORTIONING AND BY− PASS
VALVE (LSP & BV)
1996 LAND CRUISER (RM451U)
INSTALLATION
1. INSTALL LSP & BV ASSEMBLY
Install the LSP & BV assembly to the frame with the 4 bolts. Torque: 25 N·m (260 kgf·cm, 19 ft·lbf)
2. CONNECT SHACKLE NO.2 TO BRACKET
(a) Set the dimension A by turning shackle No.2. Initial set: 90 mm (3.54 in.)
(b) Tighten the lock nut. Torque: 25 N·m (250 kgf·cm, 18 ft·lbf)
(c) Install the 2 bushings and collar to the load sensing spring
shackle.
(d) Install the load sensing spring shackle to the shackle bracket with a retainer and nut.
Torque: 13 N·m (130 kgf·cm, 9 ft·lbf)
(e) Install a new cotter pin.
3. CONNECT BRAKE LINES
Using SST, connect the 3 brake lines. SST 09751−36011
Torque: 15 N·m (155 kgf·cm, 11 ft·lbf)
4. SET REAR AXLE LOAD (See page BR−45 )
5. SET VALVE BODY
(a) When pulling down the load sensing spring, confirm that the valve piston moves down smoothly.
(b) Position the valve body so that the valve piston lightly contacts the load sensing spring.
(c) Tighten the 2 valve body mounting nuts. Torque: 13 N·m (130 kgf·cm, 9 ft·lbf)
6. BLEED BRAKE SYSTEM (See page BR−4 )
7. CHECK FLUID LEAKAGE
8. CHECK AND ADJUST LSP & BV FLUID PRESSURE (See page BR−45 )

BRAKE FRONT SPEED SENSOR
BR−61
1996 LAND CRUISER (RM451U)
REMOVAL
HINT:
When replacing the sensor or sensor harness, replace the sen-
sor and sensor harness together as a set.
1. DISCONNECT SPEED SENSOR CONNECTOR
2. REMOVE SPEED SENSOR
(a) Remove the 8 clamp bolts holding the sensor harness
from the axle housing.
(b) Remove the bolt and wire tie holding the sensor harness from the stabilizer bar.
(c) Remove the bolt and 2 clips holding the sensor harness

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.
