BRAKE FRONT BRAKE CALIPER
BR−27
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 ).

REPLACEMENT
1. REMOVE REAR WHEEL
Remove the wheel and temporarily fasten the disc with the hub
nuts.
2. INSPECT PAD LINING THICKNESS
Check the pad thickness through the caliper inspection hole
and replace pads if the thickness is not within the specification.
Minimum thickness: 1.0 mm (0.039 in.)
3. REMOVE BRAKE CALIPER
(a) Remove the sliding main pin and sliding sub pin.
(b) Remove the caliper and suspend it so the hose is not stretched.
HINT:
Do not disconnect the flexible hose.
4. REMOVE THESE PARTS:
(a) 2 brake pads
(b) Anti−squeal shim
(c) 4 pad support plates
(d) 2 pad wear indicator 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.
5. CHECK DISC THICKNESS AND RUNOUT (See page BR−36 )
6. INSTALL PAD SUPPORT PLATES
7. INSTALL NEW PADS
NOTICE:
When replacing worn pads, the anti −squeal shim and wear
indicator plates must be replaced together with the pads.

BRAKE REAR BRAKE PAD
1996 LAND CRUISER (RM451U)
(a) Install pad wear indicator plate to each pads.
(b) Install the anti−squeal shim to the outer pad.
(c) Install the 2 pads so the wear indicator plate is facing up-
ward.
NOTICE:
Do not allow oil or grease to get on the rubbing face.
8. INSTALL CALIPER
(a) Draw out a small amount of brake fluid from the reservoir.
(b) Press in piston with a hammer handle or an equivalent.
HINT:
Always change the pads on one wheel at a time as there is a
possibility of the opposite piston flying out.
(c) Install the caliper carefully so the boot is not wedged.
(d) Install and torque the sliding main pin and sub pin. Torque: 88 N·m (900 kgf·cm, 65 ft·lbf)
9. INSTALL REAR WHEEL
10. CHECK THAT FLUID LEVEL IS AT MAX LINE

CHARGING SYSTEM
ON−VEHICLE INSPECTION
1. CHECK BATTERY ELECTROLYTE LEVEL AND VOLT-
AGE
(a) Check the electrolyte quantity of each cell.
If under the lower level, replace the battery (or add distilled wa-
ter if possible). check the charging system.
(b) Measure the battery voltage between the negative ( −)
and positive (+) terminals of the battery.
Standard voltage: At 20° C (68°F): 12.7 − 12.9 V
HINT:
Before measuring the voltage, turn the ignition switch
OFF and turn off the electrical systems (headlight, blower
motor, rear defogger etc.).
If the vehicle has been running, wait 20 minutes or more
after the vehicle stops before measuring the battery volt-
age.
If the voltage is less than specification, charge the battery.
HINT:
Check the indicator as shown in the illustration.
2. CHECK BATTERY TERMINALS, FUSIBLE LINK AND FUSES
(a) Check that the battery terminals are not loose or cor-
roded.

PRE−CHECK
1. DIAGNOSIS SYSTEM
(a) Description
When troubleshooting OBD II vehicles, the only dif-
ference from the usual troubleshooting procedure
is that you connect to the vehicle the OBD II scan
tool complying with SAE J1978 or TOYOTA hand −
held tester, and read off various data output from
the vehicle’s ECM.
OBD II regulations require that the vehicle’s on −
board computer lights up the Malfunction Indicator
Lamp (MIL) on the instrument panel when the com-
puter detects a malfunction in the computer itself or
in drive system components which affect vehicle
emissions. In addition to the MIL lighting up when
a malfunction is detected, the applicable Diagnostic
Trouble Codes (DTC) prescribed by SAE J2012 are
recorded in the ECM memory (See page DI−13).
If the malfunction does not reoccur in 3 trips, the MIL goes off
but the DTC remain recorded in the ECM memory.
To check the DTC, connect the OBD II scan tool or
TOYOTA hand−held tester to Data Link Connector
3 (DLC3) on the vehicle. The OBD II scan tool or
TOYOTA hand−held tester also enables you to
erase the DTCs and check freezed frame data and
various forms of engine data (For operating instruc-
tions, see the OBD II scan tool’s instruction book.).
DTC include SAE controlled codes and manufac-
turer controlled codes. SAE controlled codes must
be set as prescribed by the SAE, while manufactur-
er controlled codes can be set freely by the
manufacturer within the prescribed limits (See DTC
chart on page DI−13).

DTC P1780 Park/Neutral Position Switch Malfunction
CIRCUIT DESCRIPTION
The park/neutral position switch goes on when the shift lever is in the N o\
r P shift position. When it goes on
terminal NSW of the ECM is grounded to body ground via the starter relay, thus the terminal NSW voltage
becomes 0 V. When the shift lever is in the D, 2, L or R position, the park/neutral\
position switch goes off,
so the voltage of ECM, terminal NSW becomes battery voltage, the voltage of the ECM internal power
source. If the shift lever is moved from the N position to the D position, this signal is used for air\
−fuel ratio
correction and for idle speed control (estimated control), etc.
