Master Cylinder Reservoir
REMOVAL
1) Disconnect reservoir lead wire at coupler.
2) Clean outside of reservoir (1).
3) Take out fluid with syringe or such.
4) Remove reservoir stopper (3).
5) Remove reservoir (1).

1) When using new grommets, lubricate them with the same
fluid as the one to fill reservoir (1) with. Then press-fit grom-
mets to master cylinder (2). Grommets must be seated in
place.
2) Install reservoir (1) and then insert stopper (3).
3) Connect reservoir lead wire.

Master Cylinder Assembly
REMOVAL
1) Disconnect reservoir lead wire (1) at coupler.
2) Clean around reservoir cap (2) and take out fluid with
syringe or such.
3) Disconnect brake pipes from master cylinder (3) and ABS
actuator (4).
INSPECTION
Inspect distance “A” to be the following.
Distance “A” :
57.4 mm (2.26 in) or more
If measurement is out of above specification, replace master cyl-
inder assembly.
INSTALLATION
1) Install master cylinder to brake booster.
2) Tighten master cylinder attaching nuts to specified torque.
Tightening torque
Master cylinder attaching nut (b) :
13 N·m (1.3 kg-m, 9.5 lb-ft)
3) Connect hydraulic lines to master cylinder and ABS actuator
and tighten flare nuts to specified torque.
Tightening torque
Brake pipe flare nut (c) : 16 N·m (1.6 kg-m, 12.0 lb-ft)
4) Connect reservoir lead wire (1).
5) Fill reservoir with specified brake fluid.
6) After installing, check brake pedal play and bleed air from
system (Refer to “BRAKE PEDAL PLAY CHECK” and
“BLEEDING BRAKE” in Section 5).
7) Perform brake test and check each installed part for fluid
leakage. NOTE:
Do not allow brake fluid to get on painted surfaces.

CLEARANCE BETWEEN BOOSTER PISTON ROD AND
MASTER CYLINDER PISTON CHECK AND ADJUSTMENT
The length of booster piston rod (1) is adjusted to provide speci-
fied clearance “0” between piston rod (1) end and master cylinder
piston (2).
1) Before measuring clearance, push piston rod several times
so as to make sure reaction disc is in place.
2) Keep inside of booster at atmospheric pressure for measure-
ment.
3) Check depth of piston rod, i.e. distance between piston rod
and mating surface of booster-to-master cylinder.
Depth “c” of piston rod for check :
15.8 – 16.6 mm (0.623 – 0.653 in.)

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
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” 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
“LOCK” 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:
For the descriptions (items) not found in this section, refer to the same section of the Service Man-
ual mentioned in the FOREWORD of this manual.
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.

5C-2 PARKING AND REAR BRAKE
General Description
Drum Brake Assembly
The drum brake assembly has a self shoe clearance adjusting system so that drum-to-shoe clearance is main-
tained appropriate at all times. Rear brake is a drum type. It uses leading trailing operation when brake pedal is
depressed and when parking brake is applied on level road.
It also uses duo servo operation when parking brake is applied on gradient road and load is applied in longitudi-
nal direction of vehicle.
NOTE:
Replace all components included in repair kits to service this drum brake. Lubricate parts as speci-
fied.
WARNING:
If any hydraulic component is removed or brake line disconnected, bleed the brake system. The
torque values specified are for dry, unlubricated fasteners.

Inspect drum for cleanliness. Check wear of its braking surface by
measuring its inside diameter.
Whenever brake drums are removed, they should be thoroughly
cleaned and inspected for cracks, scores, deep grooves.Brake dram inside diameter “a ”
