Caliper
Before installing caliper (cylinder body) to carrier, check to ensure
that guide pin (pin bolt) inserted in each caliper carrier hole can be
moved smoothly in thrust direction.
NOTE:
Where temperature gets as low as ±30
C in cold weather, use
rubber grease whose viscosity varies very little even at ±40
C
(±40
F).
INSTALLATION
1) Install caliper to caliper carrier.
2) Torque caliper pin bolts to specifications.

INSPECTION AND CHANGE
1) Before changing or inspecting oil, be sure to stop engine and lift
vehicle horizontally.
2) With vehicle lifted up, check oil level and leakage. If leakage ex-
ists, correct or repair it.
3) Drain old oil and fill new specified oil as shown below by speci-
fied amount (roughly up to level hole).
NOTE:

It is highly recommended to use SAE 75W-90 gear oil.

Whenever vehicle is hoisted for any other service work
than oil change, also be sure to check for oil leakage and
status of breather hoses.

If water or rust is mixed in drained oil, be sure to check
breather hose and boot of transmission and transfer.

DTC CONFIRMATION PROCEDURE
WARNING:

When performing a road test, select a place where there is no traffic or possibility of a traffic accident
and be very careful during testing to avoid occurrence of an accident.

Road test should be carried out with 2 persons, a driver and a tester, on a level road.
1) Connect scan tool to DLC with ignition switch OFF.
2) Clear DTC, pending DTC and freeze frame data in PCM memory by using scan tool and check fuel level meter
indication is 1/4 or more.
3) Start engine, warm it up to normal operating temperature and shift transfer lever to ª2Hº or ª4Hº range.
4) Increase vehicle speed with D range, and check that gear position changes from 1st to 2nd and keep driving
about 20 mph, 30 km/h in 2nd of ªDº range for 10 seconds. (Throttle valve should be not at idle position and
the opening should be kept constant in this step.)
5) Keep driving about 50 mph, 80 km/h in 4th of ªDº range for 10 seconds.
6) Release accelerator pedal, decrease vehicle speed and stop vehicle.
7) Check pending DTC and DTC by using scan tool.
