FOR ALL OF VEHICLES
PRECAUTION
1. FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND
SEAT BELT PRETENSIONER
(a) The LAND CRUISER is equipped with an SRS (Supple-
mental Restraint System), such as the driver airbag and
front passenger airbag assembly.
Failure to carry out service operations in the correct se-
quence could cause the supplemental restraint system to
unexpectedly deploy during servicing, possibly leading to
a serious accident.
Further, if a mistake is made in servicing the supplemental
restraint system, it is possible the SRS may fail to operate
when required. Before servicing (including removal or
installation of parts, inspection or replacement), be sure
to read the following items carefully, then follow the cor-
rect procedure described in this manual.
(b) GENERAL NOTICE (1) Malfunction symptoms of the supplemental re-straint system are difficult to confirm, so the diag-
nostic trouble codes become the most important
source of information when troubleshooting. When
troubleshooting the supplemental restraint system,
always inspect the diagnostic trouble codes before
disconnecting the battery (See page DI−240).
(2) Work must be started after 90 seconds from the
time the ignition switch is turned to the ”LOCK” posi-
tion and the negative ( −) terminal cable is discon-
nected from the battery.
(The supplemental restraint system is equipped
with a back−up power source so that if work is
started within 90 seconds of disconnecting the neg-
ative (−) terminal cable from the battery, the SRS
may deploy.)
When the negative (−) terminal cable is discon-
nected from the battery, memory of the clock and
audio systems will be cancelled. So before starting
work, make a record of the contents memorized by
the each memory system. Then when work is fin-
ished, reset the clock and audio systems as before.
To avoid erasing the memory of each memory sys-
tem, never use a back− up power supply from anoth-
er battery.

BRAKE FRONT BRAKE PAD
1996 LAND CRUISER (RM451U)
REPLACEMENT
1. REMOVE FRONT WHEEL
2. INSPECT PAD LINING THICKNESS
Check the pad thickness and replace pads if not within the
specification. 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 and clip 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−27 )
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 an equiva- lent.
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 2 anti−squeal shims to new pads.
