(c) Ground terminal on the wire harness side through a 3.4
W test bulb.
(d) Turn the ignition switch ON, and check that the bulb lights
up and that the receiver gauge needle moves to the high
side.
If operation is not as specified, measure the receiver gauge re-
sistance.
14. INSPECT OIL PRESSURE RECEIVER GAUGE RESIS- TANCE
Measure the receiver gauge resistance between terminals. Resistance:
40 − 48 Ω
If resistance value is not as specified, replace the receiver
gauge.
15. INSPECT OIL PRESSURE SENDER GAUGE OPERA-
TION
(a) Disconnect the connector from the sender gauge.
(b) Apply battery positive voltage to the sender gauge termi- nal through a test LED.
(c) Check that the bulb does not light when the engine is stopped.
(d) Check that the LED flashes when the engine is running. The number of flashed should vary with engine speed.
If operation is not as specified, replace the sender gauge.
16. INSPECT BRAKE WARNING LIGHT
(a) Disconnect the connectors from the level warning switch and parking brake switch.
(b) Connect terminals on the wire harness side connector of
the level warning switch connector.
(c) Turn the ignition switch ON, and check that the warning light lights up.
17. INSPECT PARKING BRAKE SWITCH
(a) Check that there is continuity between terminal and the switch set nut with switch pin released (parking brake le-
ver pulled up).
(b) Check that there is no continuity between terminal and the switch set nut with switch pin pushed in. (parking
brake lever released)
If operation is not as specified, replace the switch.

18. INSPECT BRAKE FLUID LEVEL WARNING SWITCH
(a) Check that there is no continuity between terminals with
the switch OFF (float up).
(b) Check that there is continuity between terminals with the switch ON (float down).
If operation is not as specified, replace the switch.
19. INSPECT OPEN DOOR WARNING LIGHT
(a) Disconnect the connector from the door courtesy switch and ground terminal on the wire harness side connector.
(b) Turn the ignition switch ON, and check that the warning light lights up.
If the warning light does not light up, test the bulb.
20. INSPECT DOOR COURTESY SWITCH
(a) Check that there is continuity between terminal and the
switch body with the switch ON (switch pin re-
leased:opened door).
(b) Check that there is no continuity between terminal and
the switch body with the switch OFF (switch pin pushed
in:closed door).
If operation is not as specified, replace the switch.
21. INSPECT SEAT BELT WARNING LIGHT
(a) Disconnect the connector from the seat belt warning relay.
(b) Ground terminal 9 on the wire harness side connector.
(c) Turn the ignition switch ON, and check that the warning
light lights up.
If the warning light does not light up, test the bulb.
22. INSPECT SEAT BELT BUCKLE SWITCH CONTINUITY
(a) Check that there is continuity between terminals with the switch ON (belt unfastened).
(b) Check that there is no continuity between terminals with the switch OFF (belt fastened).
If operation is not as specified, replace the seat belt inner.

BRAKE PEDAL
ON−VEHICLE INSPECTION
1. CHECK PEDAL HEIGHT
Pedal height from dash panel:
167.5 − 177.5 mm (6.594 − 6.988 in.)
2. IF NECESSARY, ADJUST PEDAL HEIGHT
(a) Disconnect the connector from the stop light switch.
(b) Loosen the stop light switch lock nut and remove the stop
light switch.
(c) Loosen the push rod lock nut.
(d) Adjust the pedal height by turning the pedal push rod.
(e) Tighten the push rod lock nut. Torque: 25 N·m (260 kgf·cm, 19 ft·lbf)
(f) Install the stop light switch and turn it until it lightly con-
tacts the pedal stopper.
(g) Turn the stop light switch back one turn.
(h) Check the clearance (A) between the stop light switch and pedal.
Clearance: 0.5 − 2.4 mm (0.020 − 0.094 in.)
(i) Tighten the stop light switch lock nut.
(j) Connect the connector to the stop light switch.
(k) Check that the stop lights come on when the brake pedal
is depressed, and go off when the brake pedal is re-
leased.
(l) earance (A) between the stop light switch and the pedal
stopper has been adjusted correctly, the pedal freeplay
will meet the specifications.
3. CHECK PEDAL FREEPLAY
(a) Stop the engine and depress the brake pedal several times until there is no more vacuum left in the booster.
(b) Push in the pedal by hand until the beginning of the se- cond resistance is felt. Measure the distance.
Pedal freeplay: 3 − 6 mm (0.12 − 0.24 in.)
HINT:
The freeplay to the 1st resistance is due to the play between the
clevis and pin. This is magnified up to 3 − 6 mm (0.12 − 0.24 in.)
at the pedal.

If incorrect, check the stop light switch clearance.
If the clearance is OK, then troubleshoot the brake system.
4. CHECK PEDAL RESERVE DISTANCE
Release the parking brake.
With the engine running, depress the pedal and measure
the pedal reserve distance, as shown.
Pedal reserve distance, ’a’, at 490 N (50 kgf, 110.2lbf):
More than 68 mm (2.68 in.)
If the reserve distance incorrect, troubleshoot the brake sys-
tem.

(a) Remove the set screw and pull out the reservoir.
Torque: 1.7 N´m (17.5 kgf´cm, 15.2 in.´lbf)
(b) Remove the cap and strainer from the reservoir.
2. REMOVE 2 GROMMETS
3. REMOVE BOLT AND CLAMP FROM CYLINDER BODY
4. PLACE CYLINDER IN VISE
5. REMOVE PISTON STOPPER BOLT
Using a screwdriver, push the pistons in all the way and remove
the piston stopper bolt and gasket.
HINT:
Tape the screwdriver tip before use. Torque: 10 N´m (100 kgf´cm, 7 ft´lbf)
6. REMOVE 2 PISTONS AND SPRINGS
(a) Push in the piston with a screwdriver and remove the snap ring with snap ring pliers.
HINT:
Tape the screwdriver tip before use.
(b) Remove the No.1 piston and spring by hand, pulling straight out, not at an angle.
NOTICE:
If pulled out and installed at an angle, there is a possibly
that the cylinder bore could be damaged.
NOTICE:
Be careful not to damage the rubber lips on the pistons.
(c) Place a rag and 2 wooden blocks on the work table, and lightly tap the cylinder flange against the block edges until
the No.2 piston drops out of the cylinder.

1996 LAND CRUISER (RM451U)
BRAKE BOOSTER ASSEMBLY
OPERATION
1. OPERATING CHECK
(a) Depress the brake pedal several times with the engine off
and check that there is no change in the pedal reserve
distance.
(b) Depress the brake pedal and start the engine. If the pedal
goes down slightly, operation is normal.
2. AIR TIGHTNESS CHECK
(a) Start the engine and stop it after 1 or 2 minutes. Depress the brake pedal several times slowly. If the pedal goes
down furthest the 1st time, but gradually rises after the
2nd or 3rd time, the booster is air tight.
(b) Depress the brake pedal while the engine is running, and
stop the engine with the pedal depressed. If there is no
change in the pedal reserve travel after holding the pedal
for 30 seconds, the booster is air tight.
