BRAKE PEDAL FREE HEIGHT ADJUSTMENT
1) Check brake pedal free height.
If it is not within specification, check and adjust following
item 1) and 2).
Brake pedal free height “a” from dash silencer
LH steering vehicle : 205 – 225 mm (8.08 – 8.85 in.)
RH steering vehicle : 217 – 237 mm (8.55 – 9.33 in.)
2) Check measurement between booster mounting surface and
center of clevis pin hole. When booster push rod clevis has
been reinstalled, it is important that the measurement is
adjusted (refer to BRAKE BOOSTER INSPECTION AND
ADJUSTMENT).
3) Check stop light switch position. Adjust it if it is out of specifi-
cation.
BRAKE PEDAL PLAY INSPECTION
Pedal play should be within specification below. If out of specifi-
cation, check stop light switch for proper installation position and
adjust if necessary.
Also check pedal shaft bolt and master cylinder pin installation for
looseness and replace if defective.
Brake pedal play
“a” : 1 - 8 mm (0.04 - 0.31 in.)
STOP LIGHT SWITCH ADJUSTMENT
Adjustment should be made as follows when installing switch.
Pull up brake pedal toward you and while holding it there, adjust
switch position so that clearance between end of thread and
brake pedal is as specified. Then adjust stop light switch assem-
bly position and lock it by turning clockwise.
Clearance between brake pedal and stop light switch
“a” : 0.5 - 1.5 mm (0.02 -0.06 in.)

5) If rear brake pressure is not within specification, adjust it by
changing bolt (2) position as follows.
If rear brake pressure is higher than specification, move bolt
(2) center side and if it is lower, out side.
Repeat steps 3) and 4) until rear brake pressure is within
specification.
After adjustment, be sure to torque nut (1) to specification.
Tightening torque
LSPV nut (a) : 25 N·m (2.5 kg-m, 18.0 lb-ft)
6) Upon completion of fluid pressure test, bleed brake system
and perform brake test.
MASTER CYLINDER AND BRAKE FLUID
LEVEL INSPECTION
1) Check master cylinder and reservoir tank for crack, damage
and brake fluid leakage. If any faulty condition exists, correct
or replace.
2) Check that brake fluid level is between MAX and MIN marks
on reservoir tank.

1, (a)
NOTE:
Be sure to use particular brake fluid either as indicated
on reservoir cap of that vehicle or recommended in
owner’s manual which comes along with that vehicle.
Use of any other fluid is strictly prohibited.
Fluid level should be between MIN and MAX lines marked
on reservoir.
When brake warning lamp lights sometimes during driv-
ing, replenish fluid to MAX level.
When fluid decreases quickly, inspect brake system for
leakage. Correct leaky points and then refill to specified
level.
CAUTION:
Do not use shock absorber fluid or any other fluid which
contains mineral oil. Do not use a container which has
been used for mineral oil or a container which is wet from
water. Mineral oil will cause swelling and distortion of
rubber parts in hydraulic brake system and water mixed
into brake fluid will lower fluid boiling point. Keep all fluid
containers capped to prevent contamination.

BRAKE HOSE AND PIPE INSPECTION
HOSE
The brake hose assembly should be checked for road hazard
damage, for cracks and chafing of outer cover, for leaks and blis-
ters. A light and mirror may be needed for an adequate inspec-
tion. If any of above conditions are observed on brake hose, it is
necessary to replace it.
PIPE
Inspect the pipe for damage, cracks, dents and corrosion. If any
defect is found, replace it.
ON-VEHICLE SERVICE
AIR BLEEDING OF BRAKE SYSTEM
Bleeding operation is necessary to remove air whenever it
entered hydraulic brake system.
Hydraulic lines of brake system are based on the diagonal split
system. When a brake pipe or hose was disconnected at the
wheel, bleeding operation must be performed at both ends of the
line of the removed pipe or hose. When any joint part of the mas-
ter cylinder of other joint part between the master cylinder and
each brake (wheel) was removed, the hydraulic brake system
must be bled at all 4 wheel brakes.
CAUTION:
Brake fluid is extremely damaging to paint. If fluid should
accidentally touch painted surface, immediately wipe
fluid from paint and clean painted surface.
NOTE:
Perform bleeding operation starting with wheel cylinder
farthest from master cylinder and then at front caliper of
the same brake line. Do the same on the other brake line.

2. Left brake caliper A : FRONT
3. Right wheel cylinder B : REAR

5-28 BRAKES
INSTALLATION
1) Put flat end rod or the like between rod (1) and ratchet (2)
and pull ratchet as shown to maximize clearance between
shoe and drum.
2) Install brake drum (1) after making sure that inside of brake
drum and brake shoes are free from dirt and oil.
3) Install new spindle nut (2). (For 2WD vehicle only)
4) Tighten spindle nut (2) to specified torque. (For 2WD vehicle
only)

30 kg (66 lbs) load 3 to 5 times so as to obtain proper drum-
to-shoe clearance.
9) Adjust parking brake cable. Refer to “PARKING BRAKE

10) Check to make sure that brake drum is free of dragging and
brake works properly. Then remove vehicle from lift and per-
form brake test.
NOTE:
Removed spindle nut should be replaced with new one.
NOTE:
When installing spindle cap, hammer lightly several
locations on the collar of cap until collar comes closely
into contact with brake drum.

fitted loosely, replace with new one.

ANTILOCK BRAKE SYSTEM (ABS) 5E-3
The main component parts of this ABS include the following parts in addition to those of the conventional brake
system.
Wheel speed sensor which senses revolution speed of each wheel and outputs its signal.
ABS warning lamp which lights to inform abnormality when system fails to operate properly.
ABS hydraulic unit/control module assembly is incorporated ABS control module, ABS hydraulic unit (actua-
tor assembly), fail-safe relay and pump motor relay.
–ABS control module which sends operation signal to ABS hydraulic unit to control fluid pressure applied to
each wheel cylinder based on signal from each wheel speed sensor so as to prevent wheel from locking.
–ABS hydraulic unit which operates according to signal from ABS control module to control fluid pressure
applied to wheel cylinder of each 4 wheels.
–Fail-safe relay (solenoid valve) relay which supplies power to solenoid valve in ABS hydraulic unit and
pump motor relay.
–Pump motor relay which supplies power to pump motor in ABS hydraulic unit.
G sensor which detects body deceleration speed. (For 4WD model only)]
This ABS is equipped with Electronic Brake force Distribution (EBD) system that controls a fluid pressure of rear
wheels to best condition, which is the same function as that of proportioning valve, by the signal from wheel sen-
sor independently of change of load due to load capacity and so on. And if the EBD system fails to operate prop-
erly, the brake warning lamp lights to inform abnormality.

ANTILOCK BRAKE SYSTEM (ABS) 5E-5
ABS HYDRAULIC UNIT/CONTROL MODULE
ASSEMBLY
ABS control module is a component of ABS hydraulic unit/control
module assembly and has the following functions.
SELF-DIAGNOSIS FUNCTION
ABS control module diagnoses conditions of the system compo-
nent parts (whether or not there is any abnormality) all the time
and indicates the results (warning of abnormality occurrence and
DTC) through the ABS warning lamp as described below.
1) When ignition switch is turned ON, ABS warning lamp lights
for 2 seconds to check its bulb and circuit.
2) When no abnormality has been detected (the system is in
good condition), ABS warning lamp turns OFF after 2 sec-
onds.
3) When an abnormality in the system is detected, ABS warn-
ing lamp lights and the area where that abnormality lies is
stored in the memory of EEPROM in ABS control module.
4) When Diag. switch terminal (2) of diagnosis connector (1)
(monitor connector) is grounded, the abnormal area is output
as DTC. It is indicated by flashing of ABS warning lamp.
(Refer to the table below.)
5) For procedure to clear all DTC’s, refer to “DIAGNOSTIC
TROUBLE CODE CLEARANCE” in this section.
Also ABS control module turns ON EBD warning lamp (brake
warning lamp) depending on the trouble that detected by the
module and EBD warning lamp does not indicate DTC as well as
ABS warning lamp.
FAIL-SAFE FUNCTION
When an abnormality occurs (an abnormal DTC is detected),
ABS control module turns OFF the fail-safe relay which supplies
power to ABS hydraulic unit. Thus, with ABS not operating,
brakes function just like the brake system of the vehicle without
ABS.
