Pedal inspection
Check clutch pedal for height and free travel referring to Section
7C1. Adjust or correct if necessary.
Fluid inspection
1) Check around master cylinder and reservoir for fluid leakage.
If found leaky, correct.
2) Check fluid level.
If fluid level is lower than the minimum level of reservoir, refilling
is necessary. Fill reservoir with specified brake fluid indicated on
clutch reservoir cap.
For the details, refer to On-vehicle service in Section 7C1.
CAUTION:
Since clutch system of this vehicle is factory-filled with
glycol-base brake fluid, do not use or mix different type
of fluid when refilling system; otherwise serious damage
will occur. Do not use old or used brake fluid, or one taken
from unsealed container.

2) Check front disc brake pads and discs for excessive wear, dam-
age and deflection. Replace parts as necessary. For details, re-
fer to Section 5B.
Be sure to torque caliper pin bolts to specification.
[Brake drums and shoes]
1) Remove wheel and brake drum.
2) Check rear brake drums and brake linings for excessive wear
and damage, while wheels and drums are removed. At the same
time, check wheel cylinders for leaks. Replace these parts as

REAR SUSPENSION FASTENERS
Check each bolt and nut fastening suspension parts for tightness.
Tighten loose one, if any, to specified torque, referring to ªTIGHT-
ENING TORQUE SPECIFICATIONSº of this section.
BEARING RETAINER AND AXLE SHAFT
INNER OIL SEAL CHECK

When brake drum has been removed, check inside of brake drum
for gear oil leakage.

Also, check backside of brake back plate for oil leakage.
If oil leakage is found, replace defective oil seal.

Whenever it is possible to check oil seal during disassembly,
check its lip for wear.
If oil leakage or worn lip is found, replace defective oil seal.
WHEEL DISC, NUT & BEARING CHECK

Inspect each wheel disc for dents, distortion and cracks. A disc
in badly damaged condition must be replaced.

Check wheel hub nuts for tightness and retighten to specification
as necessary.
Tightening Torque
(a): 100 N
.m (10.0 kg-m, 72.5 lb-ft)

Check wheel bearings for wear. When measuring thrust play, ap-
ply a dial gauge to axle shaft center after removing wheel center
cap from wheel.
Thrust play limit
Rear0.8 mm (0.03 in.)
When measurement exceeds limit, replace bearing.

By rotating wheel actually, check wheel bearing for noise and
smooth rotation. If it is defective, replace bearing.
