TIRE
MOUNTING AND DISMOUNTING
Use a tire changing machine to mount or dismount tires. Follow equipment manufacturer’s instructions. Do not
use hand tools or tire irons alone to change tires as they may damage tire beads or wheel rim.
Rim bead seats should be cleaned with a wire brush or coarse steel wool to remove lubricants, old rubber and
light rust. Before mounting or dismounting a tire, bead area should be well lubricated with approved tire lubri-
cant.
After mounting, inflate to specified pressure shown on tire placard so that beads are completely seated.
Install valve core and inflate to proper pressure.
REPAIR
There are many different materials and techniques on the market to repair tires. As not all of these work on all
types of tires, tire manufacturers have published detailed instructions on how and when to repair tires. These
instructions can be obtained from each tire manufacturer.WARNING:
Do not stand over tire when inflating. Bead may break when bead snaps over rim’s safety hump and
cause serious personal injury.
Do not exceed specified pressure when inflating. If specified pressure will not seat beads, deflate, re-
lubricate and reinflate.
Over inflation may cause bead to break and cause serious personal injury.

NOTE:
All front fasteners are important attaching parts in that they could affect the performance of vital parts
and systems, and/or could result in major repair expense. They must be replaced with one of same
part number or with an equivalent part if replacement becomes necessary. Do not use a replacement
part of lesser quality or substitute design. Torque values must be used as specified during reassem-
bly to assure proper retention of all parts. There is to be no welding as it may result in extensive dam-
age and weakening of the metal.

5-2 BRAKES
GENERAL DESCRIPTION
When the foot brake pedal is depressed, hydraulic pressure is developed in the master cylinder to actuate pis-
tons (two in front and four in rear).
The master cylinder is a tandem master cylinder. Brake pipes are connected to the master cylinder and they
make two independent circuits. One connects front right & rear left brakes and the other connects front left &
rear right brakes.
The load sensing proportioning valve (LSPV) or the proportioning valve (P valve) is included in these circuits
between the master cylinder and the rear brake for the vehicle without ABS.
In this brake system, the disc brake type is used for the front wheel brake and a drum brake type (leading/trailing
shoes) for the rear brake.
The parking brake system is mechanical. It applies brake force to only rear wheels by means of the cable and
mechanical linkage system. The same brake shoes are used for both parking and foot brakes.

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.
