Maintenance and Minor Adjustments
Wheel and Tire
Wheel repairs that use welding, heating, or peening are not approved. All damaged wheels should be replaced.
Studs
If a broken stud is found, see Section 3E (rear) or Section 3D (front) for Note and Replacement procedure.
Matched tires and wheels
(For vehicle equipped with steel wheels)
Tires and wheels are matchmounted at the assembly plant.
This means that the radially stiffest part of the tire, or “high spot”,
is matched to the smallest radius or “low spot” of the wheel.
This is done to provide the smoothest possible ride.
The “high spot” of the tire is originally marked by paint dot (1) on
the outboard sidewall. This paint dot will eventually wash off the
tire.
The “low spot” of the wheel is originally marked by paint dot (2) on
the wheel rim-flange. Properly assembled, the wheel rim’s paint
dot should be aligned with the tire’s paint dot as shown in left fig-
ure.
Whenever a tire is dismounted from its wheel, it should be
remounted so that the tire and wheel are matched. If the tire’s
paint dot cannot be located, a line should be scribed on the tire
and wheel before dismounting to assure that it is remounted in
the same position.
Inflation of Tires
The pressure recommended for any model is carefully calculated to give a satisfactory ride, stability, steering,
tread wear, tire life and resistance to bruises.
Tire pressure, with tires cold, (after vehicle has set for three hours or more, or driven less than one mile) should
be checked monthly or before any extended trip. Set to the specifications on the tire placard located on the
driver’s side door lock pillar.
It is normal for tire pressure increase when the tires become hot during driving. Do not bleed or reduce tire pres-
sure after driving. Bleeding reduces the “Cold Inflation Pressure.”
Higher than Recommended Pressure Can Cause:
1) Hard ride
2) Tire bruising or carcass damage
3) Rapid tread wear at center of tire
Unequal Pressure on Same Axle Can Cause:
1) Uneven braking
2) Steering lead
3) Reduced handling
4) Swerve on acceleration
Valve caps should be kept on valves to keep dust and water out.
Downloaded from www.Manualslib.com manuals search engine WHEELS AND TIRES 3F-7
Lower than Recommended Pressure Can Cause:
1) Tire squeal on turns
2) Hard steering
3) Rapid and uneven wear on the edges of the tread
4) Tire rim bruises and rupture
5) Tire cord breakage
6) High tire temperatures
7) Reduced handling
8) High fuel consumption
Tire placard
The tire placard is located on the driver’s side door lock pillar and should be referred to for tire information. The
placard lists the maximum load, tire size and cold tire pressure where applicable.
Tire rotation
To equalize wear, rotate tires according to left figure. Radial tires
should be rotated periodically. Set tire pressure. NOTE:
Whether rim size and/or maximum load are listed or not depends on regulations of each country.
NOTE:
Due to their design, radial tires tend to wear faster in the
shoulder area, particularly in front positions. This makes
regular rotation especially necessary.

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. Three (or two) brake pipes are connected to the master cylin-
der and they make two independent circuits. One connects front brakes (right and left) and the other connects
rear brakes (right and left).
The load sensing proportioning valve (LSPV), the proportioning and bypass (P & B) valve or proportioning (P)
valve is included in these circuits between the master cylinder and the rear brake.
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 wheel 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.
NOTE:
The figures shows left-hand steering vehicle.
WARNING:
If any hydraulic component is removed or brake line disconnected, bleed the brake system. The
torque values specified are for dry, unlubricated fasteners.
