ACTION WHEN BATTERY RUNS OUT
When the engine is started using a booster cable where the
battery has completely run down and you attempt to start
the vehicle without waiting for the battery to recover a certain
charge, the engine can misfire and you just cannot start to
move it. In such cases, charge the battery sufficiently; or,
remove the AYC battery cable from the battery fuse assembly
to make AYC inactive before attempting to start the vehicles.
When the battery cable is removed, the ACD mode indicator
lamp lights up. After the battery has been recharged, fit the
battery cable back again and start the engine to ensure that
the ACD mode indicator lamp is off.

Caution
1. If the vehicle is equipped with the Brembo disc brake, during maintenance, take care not to
contact the parts or tools to the caliper because the paint of caliper will be scratched. And
if there is brake fluid on the caliper, wipe out quickly.
2. With the part marked with *, first temporarily tighten it, then ground the vehicle and tighten
it to specification in unloaded condition.

1. Align the alignment mark on differential case A with that
on differential case B.
2. Tighten the screws connecting differential case A and
B a uniform amount little by little in the diagonal order.
NOTE
If tightening the screws does not bring the two cases
properly together, spring plates are not probably
assembled properly. Reassemble from the start.
"CALSD DIFFERENTIAL TORQUE CHECK

DIFFERENTIAL CASE INTERNAL PARTS CONTACT/
SLIDING SURFACE CHECK
1. Clean the disassembled parts with cleaning oil and dry
them with compressed air.
2. Check each plate, disc, and pressure ring for the following:
A. Friction and sliding surfaces of friction discs, friction
plates, and spring plates.
Replace a defective part with heat discoloration and
excessive wear with a new one, as it degrades locking
performance.
NOTE
If the inner periphery of the friction face shows traces
of harsh contact, it is because of the spring tension
of each plate, disc and other part. Do not confuse
this with abnormal wear.
B. Inner periphery and outer periphery protrusions of
friction discs, friction plates, and spring plates.
Replace a cracked or damaged part with a new one.
C. Friction and sliding surfaces between pressure rings
and friction discs.
Grind a dented or scratched part with oil stone and
then lap and correct with a compound on a surface
plate.
NOTE
If the inner periphery of the friction face shows traces
of harsh contact, it is because of the spring tension
of each plate, disc and other part. Do not confuse
this with abnormal wear.
3. Check the following parts for contact and siding surfaces
(D to M) and correct burrs and dents with oil stone.
D: Sliding surfaces of side gear and case
E: Contacting surfaces of differential case and spring
plate
F: Contacting surfaces of pressure ring and differential

BASIC BRAKE SYSTEM -Disc Brake35A-21
INSTALLATION SERVICE POINT
"AADISC BRAKE ASSEMBLY INSTALLATION

1. In order to measure the brake drag force after pad
installation, measure the rotary-sliding resistance of the
hub by the following procedure with the pads removed.
(1) Withdraw the drive shaft. (Refer to GROUP 26, 27.)
(2) Attach the special tool to the front hub assembly as
shown in the illustration, and tighten it to the specified
torque.
Tightening torque:
245±29 N·m , 225±25 N·m
(3) Use a spring balance to measure the rotary-sliding
resistance of the hub in the forward direction.
2. Install the caliper support to the knuckle, and then
assemble the pad and the clip to the caliper support.
Caution
Do not contaminate the friction surfaces of the pads
and brake discs by any oil or grease.
3. Clean the piston and insert it into the cylinder with the
special tool.
4. Be careful that the piston boot does not become caught,
when lowering the caliper assembly and install the guide
pin to the caliper.
5. Start the engine, and then depress the brake pedal two
or three times strongly. Then stop the engine.
6. Turn the brake disc forward 10 times.
7. Use a spring balance to measure the rotary-sliding
resistance of the hub in the forward direction.
8. Calculate the drag force of the disc brake [difference
between the values measured at steps 1 and 7].
Standard value:
51 N or less , 69 N or less
9. If that drag force exceeds the standard value, disassemble
the piston assembly. Then check the piston for
contamination or rust, and confirm if the piston or the
piston seal is deteriorated, and if the slide pins slide
smoothly.

1. Find the drag force of the disc brake. (Refer to P.35A-13.)
Standard value: 69 N or less
2. If that drag force exceeds the standard value, disassemble
the piston assembly. Then check the piston for
contamination or rust, and confirm if the piston or the
piston seal is deteriorated.MB990998
