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 ”

(DTC 26) – Left-Front Wheel Speed 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 Section 5E1 of the Service Manual
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.
