INTRODUCTION
This article contains information on repair and service of
basic hydraulic brake system. If vehicle is equipped with anti-lock
brakes, also see appropriate ANTI-LOCK article.
DESCRIPTION
Brake system consists of a master cylinder, vacuum power
brake booster, proportioning valve and self-adjusting assembly.
Montero has a Load-Sensing Proportioning Valve (LSPV). All models are
equipped with front disc brakes and either rear disc or drum brakes.
Parking brake assembly activates rear brakes.
BLEEDING BRAKE SYSTEM
BLEEDING PROCEDURES
Bleed brakes whenever hydraulic lines are opened or pedal
feels spongy. Bleed system in appropriate sequence. See
BRAKE LINE BLEEDING SEQUENCE table. Use only DOT 3 or DOT 4 approved
fluid and DO NOT mix fluid types.

ADJUSTMENTS
BRAKE PEDAL HEIGHT, FREE PLAY & CLEARANCE
1) To measure brake pedal height, pull up carpet under brake
pedal. Measure distance between floor board and middle of brake pedal
pad surface with brake pedal released. See BRAKE PEDAL HEIGHT
SPECIFICATIONS table.
2) To adjust pedal height, separate connector from stoplight
switch, and loosen switch lock nut. Back-off switch so it does not
contact brake pedal arm. Loosen master cylinder push rod lock nut.
Adjust brake pedal height by rotating master cylinder push rod until
brake pedal height is within specification.

PARKING/EMERGENCY BRAKE
NOTE: Adjust service brakes before adjusting parking brake.
Start engine, and apply brake pedal. Pull parking brake lever
with a force of 44-45 lbs. (196-200 N). Parking brake lever should
move up 3-5 notches on Diamante, Stealth and 3000GT, 4-6 notches on
Montero, and 5-7 notches on all other models. If adjustment is
necessary, turn adjusting nut located under console or at end of cable
rod. See Fig. 6.

COMPUTER RELEARN PROCEDURES
1998 Mitsubishi Montero
GENERAL INFORMATION
Computer Relearn Procedures
All Models
* PLEASE READ THIS FIRST *
The following general procedures are to be used if
driveability problems are encountered after power loss or battery has
been disconnected. These procedures may provide an aid in eliminating
these problems.
To reduce the possibility of complaints, after any service
which requires battery power to be disconnected, vehicle should be
road tested.
COMPUTER RELEARN PROCEDURES
Vehicles equipped with engine or transmission computers may
require a relearn procedure after vehicle battery is disconnected.
Many vehicle computers memorize and store vehicle operation patterns
for optimum driveability and performance. When vehicle battery is
disconnected, this memory is lost. The computer will use default data
until new data from each key start is stored. As computer memorizes
vehicle operation for each new key start, driveability is restored.
Vehicle computers may memorize vehicles operation patterns for 40 of
more key starts.
Customers often complain of driveability problems during
relearn stage because vehicle acts differently then before being
serviced. Depending on type and make of vehicle and how it is
equipped, the following complaints (driveability problems) may exist:
* Harsh Or Poor Shift Quality
* Rough Or Unstable Idle
* Hesitation Or Stumble
* Rich Or Lean Running
* Poor Fuel Mileage
These symptoms and complaints should disappear after a number
of drive cycles have been memorized. To reduce the possibility of
complaints, after any service which requires battery power to be
disconnected, vehicle should be road tested. If a specific relearn
procedure is not available, the following procedure may be used:
Automatic Transmission
* Set parking brake, start engine in "P" or "N" position.
Warm-up vehicle to normal operating temperature or until
cooling fan cycles.
* Allow vehicle to idle for one minute in "N" position. Select
"D" and allow engine to idle for one minute.
* Accelerate at normal throttle position (20-50%) until vehicle
shifts into top gear.
* Cruise at light to medium throttle.
* Decelerate to a stop, allowing vehicle to downshift, and use
brakes normally.
* Process may be repeated as necessary.

DESCRIPTION & OPERATION
WARNING: Deactivate air bag system before performing any service
operation. See AIR BAG RESTRAINT SYSTEMS article. Do not
apply electrical power to any component on steering column
without first deactivating air bag system. Air bag may
deploy.
Cruise control system is electronically and vacuum
controlled. System components include a control unit, actuator, vacuum
pump, cruise control switch, clutch pedal position switch (M/T),
cruise indicator light, diode, Park/Neutral (P/N) switch (A/T),
stoplight switch, vehicle speed sensor and A/T control unit (if
equipped).
System has self-diagnostic capability. When self-diagnostic
mode is activated, each switch and sensor is checked for defects. When
cruise control system has been canceled without using a normal cancel
method, a trouble code will be set and stored in control unit. Trouble
codes can be retrieved to help determine which circuit is
malfunctioning.

ADJUSTMENTS
CRUISE CONTROL CABLE
Remove link protector. Loosen lock nut. Hold link "A" so that
it touches link "B". Adjust free play by turning adjusting nut until
free play is.04-.08" (1-2 mm). Tighten lock nut. See Fig. 1 or 2.
Page 319 of 1501
CRUISE CONTROL INDICATOR TEST under COMPONENT TESTS. If cruise control
indicator is defective, replace indicator. If indicator checks okay,
go to next step.
2) If cruise control indicator illuminates when cruise
control connector C-50 terminal No. 23 is grounded at harness side,
replace cruise control ECU. If indicator does not illuminate, check
combination meter connector C-12 and cruise control ECU connector C-
50. Repair as necessary. If connectors are okay and malfunction
remains, check harness between combination meter and cruise control
ECU. Repair as necessary.
Test No. 13
1) Perform stoplight switch test. See
BRAKELIGHT/STOPLIGHT SWITCH TEST under COMPONENT TESTS. If switch is
okay, go to next step. If switch is defective, replace brakelight
switch.
2) Check cruise control ECU connector C-50, stoplight switch
connector C-55 and joint connector C-131. Repair as necessary. See
Figs. 13 , 14, 16 and 29. If connectors are okay and malfunction
remains, check harness between joint connector C-131 and cruise
control ECU.
Test No. 14 (A/T)
1) Perform park/neutral switch test. See
PARK/NEUTRAL SWITCH TEST under COMPONENT TESTS. If switch is okay, go
to next step. If switch is defective, replace switch.
2) Check starter relay. Replace if defective. If relay is
okay, check cruise control ECU connector C-50 and joint connector C-
130. Repair as necessary. See Figs. 13, 16 and 28. If connectors are
okay and malfunction remains, check harness between cruise control ECU
and power supply.
COMPONENT TESTS
ACTUATOR TEST
Remove actuator. Apply vacuum to actuator. Actuator linkage
holder should move more than 1.38" (35 mm). Actuator diaphragm should
hold vacuum. Replace actuator if actuator does not test as specified.
BRAKELIGHT/STOPLIGHT SWITCH TEST
Disconnect stoplight switch connector C-55. When brake pedal
is pressed, continuity should be present between terminals No. 2 and
3. See Fig. 14. When brake pedal is released, continuity should be
present between terminals No. 1 and 4. Replace switch if it does not
test as specified.
CLOCKSPRING TEST
WARNING: Deactivate air bag system before performing any service
operation. See AIR BAG RESTRAINT SYSTEMS article. Do not
apply electrical power to any component on steering column
without first deactivating air bag system. Air bag may
deploy.
If clockspring fails any check, replace with a NEW
clockspring.
1) Check connectors and protective tube for damage and
deformities.
2) Visually check case for damage or deformities.
