2) Cut oil seal in place with scissors or a knife,
and take it off.
3) Cut replacement oil seal at one place with
scissors or a knife as shown in below figure.
4) Install the seal in oil seal retainer, bringing
the cut portion to top side and locating it
about 30 degrees off the matching face of
oil seal retainer.
5) Apply grease to inside of oil seal. Apply
sealing compound to mating face all around:
this is for preventing entry of water.

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

7) To check free wheeling hub operation, jack
up the front end, move the knob of free
wheeling hub between “FREE” and “LOCK”
positions and check for smoothness. Also
check if wheel operates correctly with the
knob at “FREE” and “LOCK” positions
and by rotating wheel by hand.
Maintenance Service
The car equipped with free wheeling hubs are
subject to the following periodical checks.
To check free wheeling hubs operation, jack up
the front end, move the knob of free wheeling
hub between “FREE” and “LOCK” positions
and check for smoothness. Also check if wheel
operates correctly with the knob at “FREE”
and “LOCK” positions and by rotating wheel by
hand.
Should the check result be unsatisfactory,
remove free wheeling hub cover and grease each
sliding surface with SUZUKI SUPER GREASE
A (99000-25010) or multipurpose grease after
cleaning each sliding part.
If faulty operation is still noted even after
greasing, correct defective part or replace it
with a new one.
CAUTION:
Hubs should not be packed with grease.
For installation, refer to “Installation Instruc-
tion” in this section.

Make an adjustment according to the following
procedure.
1) Check worm shaft to ensure that it is free
from thrust play.
2) Position pitman arm in parallel with worm
shaft as shown below.

Steering Handwheel Play
The wheel play is proper if it is anywhere
between 10 and 30 mm (0.4 and 1.2 in.). An
unusually large play means that the ball-and-
socket joints are loose or that the wear in the
steering gear box is excessively large.
Replacement of the worn joint will provide a
proper handwheel play.
If steering handwheel play is excessive though
no each joint of steering system rattles, adjust
worm shaft starting torque of steering gear box
by referring to item of “Adjustment of worm
shaft starting torque.”

Steering Shaft Joint
Check universal joint of the steering shaft for
rattle and damage, If rattle and damage is found,
replace defective part with a new one.

Steering Rubber joint
Inspect rubber joint for evidence of crack or
breakage, and make sure that its bolts are tight.

Steering Link & Tie Rod
Inspect steering link and tie rod for bend and
rattle where they are joined. Inspect ball joint
boots in steering system for leaks, detachment,
tear or other damage. If one of such malcondi-
tions is found, replace defective part with a new
one.
Check the following bolts and nuts ( @ - 0 )
for tightness and retighten them as necessary.

MASTER CYLINDER ASSEMBLY
[GENERAL DESCRIPTION]
The master cylinder has two pistons and three piston cups. Its hydraulic pressure is produced in the
primary (“a” in the below figure) and secondary (“b”) chambers. The hydraulic pressure produced in the
primary chamber (“a”) acts on the front wheel brakes (right & left).
Also, the hydraulic pressure produced in the secondary chamber (“b”) acts on the rear wheel brakes
(right & left).
NOTE:
Replace all components included in repair kits to service this master cylinder. Lubricate rubber parts with
clean, fresh brake fluid to ease assembly. Do not use lubricated shop air on brake parts as damage to rubber
components may result. If any hydraulic component is removed or brake line disconnected, bleed the
brake system. The torque values specified are for dry, unlubricated fasteners.

[Master cylinder OPERATION]
Normal operation
Depressing the brake pedal forces the primary piston“A” to move to the left in the below figure and
consequently the hydraulic pressure is produced in the chamber “a”.
By means of this pressure and the return spring force, the secondary piston “B” is also pushed to the left
and thus the hydraulic pressure is produced in the chamber “b”.

Front Brake Disc and Pad
Use care not to scratch or put oil or grease
on sliding surface of disc and pad during
installation work.
After installing brake disc to wheel hub
properly, tighten wheel nuts to specified
torque.

When fitting dust cover onto brake caliper
holder, apply SEALING COMPOUND 366E
(99000-31090) to mating surfaces of both parts.
Front Brake Flexible Hose
Connect flexible hose to caliper as shown
below and tighten hose bolt to specified
torque.
Connect the other end of hose to chassis body
bracket, being careful not to kink it with
