22. EXHAUST PRESSURE REGULATOR VALVE INSPECTION” -
Check that the valve works properly, Correct any binding. Inspect
hoses for cracks, chafing or decay. Replace parts as needed.
23. TIRE AND WHEEL ROTATION AND INSPECTION - For proper
wear and maximum tire life, rotate tires at the first 6,000 miles
(10 000
kilometers) for Schedule
I (+) or 7,500 miles (12 500 kilometers) for
Schedule
I1 (0) and then every 15,000 miles (25 000 kilometers)
thereafter. Follow the instructions and patterns shown
in Section 6.
Check tires for uneven wear or damage. If irregular or premature wear is
apparent, check wheel alignment. Also, check or damaged wheels. See
“Tires”
in the Index for more information.
For dual wheels, whenever the vehicle, wheels, or fasteners are new,
have the wheel fastener torque
set at the first 100, 1,000 and 6,000 miles
( 160, 1600 and 10 000 km).
Block the tires opposite
those being removed to keep the vehicle from
rolling.

add
as needed. Check constant velocity joints and axle seals for
leaking.

25. BRAKE SYSTEM INSPECTION? - When the engine oil is
changed, inspect the
lines and hoses for proper hookup, binding, leaks,
cracks, chafing, etc. Check
the parking brake adjust, and the fluid level
in the master cylinder.
A low fluid level can indicate worn disc brake
pads which may need to be serviced.
When the wheels are removed for rotation, inspect disc brake pads for
wear and rotors for surface condition. Also inspect drum brake linings
for wear and cracks. Inspect other brake parts, including drums, wheel
cylinders, parking brake, etc., at
the same time. Remove any rust or dirt
from the wheel and mounting surfaces before mounting
the wheel.
Inspect brakes more often if driving habits or conditions resul\
t in
frequent braking.
