WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:
Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to ªAir Bag System Components and Wiring Location Viewº under ªGener-
al Descriptionº in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and ªService Precau-
tionsº under ªOn-Vehicle Serviceº in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either of these two conditions may
result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
ªLOCKº position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:
When inspecting and servicing vehicle equipped with ABS, be sure to refer to section 5E or 5E1 first.
All brake fasteners are important attaching parts in that they could affect the performance of vital parts
and systems, and / or could result in major repair expense. They must be replaced with one of same part
number or with an equivalent part if replacement becomes necessary. Do not use a replacement part of
lesser quality or substitute design. Torque values must be used as specified during reassembly to as-
sure proper retention of all parts. There is to be no welding as it may result in extensive damage and
weakening of the metal.

4) When fluid pressure in the cylinder is almost depleted, retigh-
ten bleeder plug.
5) Repeat this operation until there are no more air bubbles in hy-
draulic line.
6) When bubbles stop, depress and hold brake pedal and tighten
bleeder plug.
For tightening torque specification of air bleeder plug, re-
fer to ªTIGHTENING TORQUE SPECIFICATIONº in this
section.
7) Then attach bleeder plug cap.
8) After completing bleeding operation, apply fluid pressure to
pipe line and check for leakage.
9) Replenish fluid into reservoir up to specified level.
10) Check brake pedal for ªsponginessº. If found spongy, repeat
entire procedure of bleeding.

BRAKE PEDAL FREE HEIGHT CHECK
Remove foot rest and displace carpet and dash silencer(s) so as to
measure brake pedal free height between pedal face and asphalt
sheet installed on dash panel.
Brake pedal free height ªaº from asphalt sheet:
208 ± 218 mm (8.19 ± 8.58 in.)
If the measurement is not within the specification, check the posi-
tion of booster push rod clevis and / or stop light switch according
to the instruction shown in this section.
The free height varies depending on installation position of booster
push rod clevis and stop light switch.
BRAKE LIGHT SWITCH ADJUSTMENT
Adjustment should be made as follows when installing switch. Pull
up brake pedal toward you and while holding it there, adjust switch
position so that clearance between end of thread and brake pedal
return cushion (shown as ªbº in figure).
Then tighten lock nut to specified torque.
Clearance ªbº: 1.5 ± 2.0 mm (0.06 ± 0.08 in.)
Tightening Torque
(b): 7.5 N
.m (0.75 kg-m, 5.5 lb-ft)
EXCESSIVE PEDAL TRAVEL CHECK
1) Remove foot rest and displace carpet and dash silencer(s).
2) Start engine.
3) Depress brake pedal a few times.
4) With brake pedal depressed with approximately 30 kg (66 lbs)
load, measure pedal to asphalt sheet clearance ªcº.
Clearance ªcº: over 115 mm (4.53 in.)
5) If clearance ªcº is less than specification, the most possible
cause is either rear brake shoes are worn out beyond limit or air
is in lines.
Should clearance ªcº remain less than specification even after
replacement of brake shoes and bleeding of system, other pos-
sible but infrequent cause is malfunction of rear brake shoe ad-
justers or booster push rod length out of adjustment.

BRAKE PEDAL PLAY CHECK
Pedal play should be within specification. If out of specification,
check brake light switch for proper installation position and adjust
if necessary.
Also check pedal shaft bolt and master cylinder pin installation for
looseness and replace if defective.
Pedal play ªdº: 1 ± 8 mm (0.04 ± 0.32 in.)
BRAKE FLUID LEVEL CHECK
Be sure to use particular brake fluid either as indicated on reservoir
cap of that vehicle or recommended in owner's manual which
comes along with that vehicle.
Use of any other fluid is strictly prohibited.
Fluid level should be between MIN and MAX lines marked on reser-
voir.
When warning light lights sometimes during driving, replenish fluid
to MAX line.
When fluid decreases quickly, inspect brake system for leakage.
Correct leaky points and then refill to specified level.
CAUTION:
Do not use shock absorber fluid or any other fluid which
contains mineral oil. Do not use a container which has been
used for mineral oil or a container which is wet from water.
Mineral oil will cause swelling and distortion of rubber parts
in hydraulic brake system and water mixed into brake fluid
will lower fluid boiling point. Keep all fluid containers
capped to prevent contamination.
BRAKE HOSE AND PIPE CHECK
The brake hose assembly should be checked for road hazard dam-
age, for cracks and chafing of the outer cover, for leaks and blisters.
A light and mirror may be needed for an adequate inspection. If any
of the above conditions are observed on the brake hose, it is neces-
sary to replace it.
Inspect the pipe for damage, cracks, dents and corrosion. If any de-
fect is found, replace it.
MASTER CYLINDER CHECK
Check for a cracked master cylinder casting or brake fluid around
the master cylinder. Leaks are indicated only if there is at least a
drop of fluid. A damp condition is not abnormal.

PARKING BRAKE CHECK AND
ADJUSTMENT
CHECK
Hold center of parking brake lever grip and pull it up with 20 kg
(40 lbs) force.
With parking brake lever pulled up as shown, count ratchet
notches.
There should be 5 to 7 notches.
Also, check if both right and left rear wheels are locked firmly.
To count number of notches easily, listen to click sounds that ratchet
makes while pulling parking brake lever without pressing its button.
One click sound corresponds to one notch.
If number of notches is out of specification, adjust cable by referring
to adjustment procedure described on the following as to obtain
specified parking brake stroke.
NOTE:
Check tooth tip of each notch for damage or wear. If any dam-
age or wear is found, replace parking brake lever.
ADJUSTMENT
NOTE:
Make sure for following conditions before cable adjustment.
No air is trapped in brake system.
Brake pedal travel is proper.
Brake pedal has been depressed a few times with about
30 kg (66 lbs) load.
Parking brake lever has been pulled up a few times with
about 20 kg (44 lbs) force.
Rear brake shoes are not worn beyond limit, and self adjust-
ing mechanism operates properly.
To slacken parking brake cable, loosen self locking nut as far
as end of bolt. Then depress brake pedal a few times with
about 30 kg (66 lbs) load.
After confirming that above 6 conditions are all satisfied, adjust
parking brake lever stroke by loosening or tightening locking nut.
NOTE:
Check brake drum for dragging after adjustment.
Parking brake stroke: 5 to 7 notches
(When lever is pulled up at 20 kg (44 lbs).)

If rear brake pressure is higher than specification, move stay
ªAº to direction ªaº and if it is lower, to direction ªbº.
Repeat steps 3) and 4) until rear brake pressure is within spec-
ification.
After adjustment, be sure to torque bolt to specification.
5) Disconnect brake pipe (connecting between master cylinder
secondary side and 4-way joint) from master cylinder.
Tighten plug (special tool) to master cylinder.
Depress brake pedal. If rear brake pressure is 95 ± 100 kg / cm

when front brake pressure is 100 kg / cm2, it means that front fail-
safe system functions properly.
