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).)

3) Depress brake pedal gradually till fluid pressure of front brake
becomes as specified below and check corresponding pressure
of rear brake then. It should be within specification given below.

check that rear brake pressure then is within specification as giv-
en below.

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.

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:
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 assure
proper retention of all parts. There is to be no welding as it may result in extensive damage and weakening
of the metal.
