WARNING:
For vehicles equipped with Supplement 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:
When inspecting and servicing vehicle equipped with ABS, be sure to refer to section 5E 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 assure proper retention of all parts. There is to be no welding as it may result
in extensive damage and weakening of the metal.

General Description
When the foot brake pedal is depressed, hydraulic pressure is developed in the master cylinder to actuate pis-
tons (two in front and four in rear).
The master cylinder is a tandem master cylinder. Three (or two) brake pipes are connected to the master cylin-
der and they make two independent circuits. One connects front brakes (right and left) and the other connects
rear brakes (right and left).
The load sensing proportioning valve (LSPV), the proportioning and bypass (P & B) valve or proportioning (P)
valve is included in these circuits between the master cylinder and the rear brake.
In this brake system, the disc brake type is used for the front wheel brake and a drum brake type (leading/trailing
shoes) for the rear wheel brake.
The parking brake system is mechanical. It applies brake force to only rear wheels by means of the cable and
mechanical linkage system. The same brake shoes are used for both parking and foot brakes.
NOTE:
The figures shows left-hand steering vehicle.
WARNING:
If any hydraulic component is removed or brake line disconnected, bleed the brake system. The
torque values specified are for dry, unlubricated fasteners.

Diagnosis
Road Testing Brakes
Brakes should be tested on dry, clean, smooth and reasonably level roadway which is not crowned. Road test
brakes by making brake applications with both light and heavy pedal forces at various speeds to determine if the
vehicle stops evenly and effectively.
Also drive vehicle to see if it leads to one side or the other without brake application. If it does, check the tire
pressure, front end alignment and front suspension attachments for looseness. See diagnosis table for other
causes.
Brake Fluid Leaks
Check the master cylinder fluid levels. While a slight drop in reservoir level does result from normal lining wear,
an abnormally low level indicates a leak in the system. In such a case, check the entire brake system for leak-
age. If even a slight evidence of leakage is noted, the cause should be corrected or defective parts should be
replaced.
If fluid level is lower than the minimum level of reservoir, refilling is necessary. Fill reservoir with specified brake
fluid.
Brake fluid: Refer to reservoir tank cap.
Substandard or Contaminated Brake Fluid
Improper brake fluid, mineral oil or water in the fluid may cause the brake fluid to boil or the rubber components
in the hydraulic system to deteriorate.
If primary piston cups are swollen, then rubber parts have deteriorated. This deterioration may also be evi-
denced by swollen wheel cylinder piston cups on the drum brake wheels.
If deterioration of rubber is evident, disassemble all hydraulic parts and wash with alcohol. Dry these parts with
compressed air before assembly to keep alcohol out of the system. Replace all rubber parts in the system,
including hoses. Also, when working on the brake mechanisms, check for fluid on the linings. If excessive fluid is
found, replace the linings.
If master cylinder piston seals are satisfactory, check for leakage or excessive heat conditions. If condition is not
found, drain fluid, flush with brake fluid, refill and bleed the system.
The system must be flushed if there is any doubt as to the grade of fluid in the system or if fluid has been used
which contained parts that have been subjected to contaminated fluid.CAUTION:
Since brake system of this vehicle is factory-filled with brake fluid indicated on reservoir tank cap, do
not use or mix different type of fluid when refilling; otherwise serious damage will occur.
Do not use old or used brake fluid, or any fluid from a unsealed container.
