PARKING BRAKE LEVER STROKE CHECKM36FEAK
1. Pull the parking brake lever with a force of approx. 200 N d(45
Ibs.), and count the number of notches.
Caution
The 200 N
(45 Ibs.) force of the parking brake lever must
be strictly observed.Standard value: 3
- 5 notches
2.If the parking brake lever stroke is not the standard value,
adjust as described below.
(1) Remove the cup holder and plug and loosen the
adjustment nut to the cable end so that the cable
becomes free.
(2) Repeat depressing the brake pedal until the pedal
stroke becomes stable.
NOTEWhen the brake pedal is repeatedly depressed, shoe
clearance is adjusted properly.
(3) Disengage the drive shaft and companion flange.
(4) Remove the adjusting hole plug. Using a screwdriver,
turn the adjuster in the direction of the arrow (to expand
the shoe) until brake is lightly applied [where the disc
cannot be turned with both hands: approx. 2.7 Nm (23in.lbs.)]. Then, turn the adjuster five notches in the
direction opposite the arrow.
(Reference: Shoe clearance on one side 0.19 mm
‘d
I.0075 in.])
(6) After the parking brake lever stroke has been adjusted,
jack up the rear part of the vehicle. Loosen the parking
brake and turn the rear wheel to check that the parking
brake does not drag.
PARKING BRAKE SWITCH CHECKM36FDAG
1.Disconnect the connector of the parking brake switch, and
connect an ohmmeter to the parking brake switch and the
switch installation bolt.
2.The parking brake switch is good if there is continuity when
the parking brake lever is pulled and there is no continuity
when it is returned.
,(JTSB Revision
(51 Turn the adjusting nut to obtain specified parking brake
lever stroke. After the adjustment, check that there is
no play between the adjusting nut and pin.
CautionDo not adjust parking brake lever stroke too tight,
less than the standard value, or brake drag could
result.

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
(1)A Supplemental Restraint System (SRS), which uses a driver-side air bag, has been installed in the 3000GT.(2)The SRS includes the following components: impact sensors, SRS diagnosis unit: SRS warning light, air bagmodule, clock spring, interconnecting wiring. Other SRS-related components (that may have to be
removed/installed in connection with SRS service or maintenance) are indicated in the table of contents byan asterisk (*).
WARNING!(I)Improper service or maintenance of any component of the SRS, or any SRS-related component, can lead to
personal injury or death to service personnel (from inadvertent firing of the air bag) or to the driver (from
rendering the SRS inoperative).
(2) Service or maintenance of any SRS component or SRS-related component must be performed only at an
authorized MITSUBISHI dealer.(3) MITSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP 52B
-Supplemental Restraint System (SRS), before beginning any service or maintenance of any component of theSRS or any SRS-related component.

STEERING 2 Service Adjustment Procedures37A-5
13FOOOi13FOOO3SERVICE ADJUSTMENT PROCEDURES
STEERING WHEEL FREE PLAY CHECKM37FABI
1.With engine running (hydraulic operation), set front wheels
straight ahead.
2. Measure the play on steering wheel circumference before
wheels start to move when slightly moving steering wheel
in both directions.
Limit: 30 mm (1.2 in.)
3:When the play exceeds the limit, check for play on steering
shaft connection and steering linkage. Correct or replace.
4. If the free play still exceeds the limit value set steering
wheel straight ahead with engine stopped. Load 5 N
(1 lb.)
towards steering wheel circumference and check play.
Standard values (steering wheel play with engine
stopped): 11 mm
(.43 in.)
If the play exceeds the standard value, remove steering
gear box and check total pinion torque.
STEERING ANGLE CHECKM37FDBK1. Set front wheels on turning radius gauge and measure
steering angle.
Standard values:Inner wheel
33”45’ k 2”
Outer wheel
28”21’2. When not within the standard value, it is probably a toe
problem. Adjust toe (refer to GROUP 33A
- Service
Adjustment Procedures) and recheck.
TIE ROD END BALL JOINT VARIATION CHECK
(SHAFT DIRECTION)M37FPAF1. Hold the ball joint with pliers.
2.Set a caliper gauge as illustrated and measure the displace-
ment with the ball stud compressed.
Limit: 1.5 mm
(.059 in.)
3. If the measured displacement exceeds the limit, replace
the tie-rod end.
Caution
Even if the variation is within the limit, check ball jointstarting torque.
