Removal
1) Raise and support vehicle. Remove front wheel(s). Separat\
e
rubber flex hose from hydraulic line at brake hose mount, located on
strut housing. Secure end of hydraulic line to prevent spillage of
brake fluid.
2) Remove hose clip from brake hose mount. Disconnect brake
hose from caliper. Remove upper and lower caliper-to-steering knuckle
bolts. Lift caliper body upward. Remove caliper.
Installation
To install, reverse removal procedure. Tighten bolts to
specification. See the TORQUE SPECIFICATIONS table. Bleed brake
system. See BLEEDING BRAKE SYSTEM .
FRONT BRAKE ROTOR
Removal (Montero, Pickup 4WD & Ram-50 4WD)
Raise and support vehicle. Remove and support brake calipers.
Place hub in free-wheeling position. Remove drive hub cover using an
oil filter wrench and protective cloth. Remove snap ring, shim and
free-wheeling hub from drive axle. See Fig. 7. Remove lock washer.
Remove lock nut using Lock Nut Wrench (MB990954). Remove front hub

Installation
1) Install front hub assembly. Install and tighten lock nut
to 94-145 ft. lbs. (127-197 N.m), and then loosen and retighten to 18
ft. lbs. (24 N.m). Loosen lock nut 30-40 degrees. Reverse removal
procedure for remaining components. After installation is complete,
check drive axle end play. Adjust end play if not .002" (.05 mm) or
less. Rotate drive axle forward and rearward until maximum end play is
obtained.
2) If adjusting axle shaft end play, use proper shim to
obtain desired end play. Shim is located behind snap ring on end of
drive axle. Install shim, and recheck axle end play.
Removal (Pickup 2WD & Ram-50 2WD)
Raise and support vehicle. Remove front caliper. Remove hub
(dust) cap, cotter pin and nut. Remove washer and outer wheel bearing.\
Remove front hub assembly. Remove bolts attaching rotor to front hub,
and separate assemblies.

CRUISE CONTROL SWITCH FUNCTION TEST
NOTE: If vehicle speed decreases approximately 9 MPH below set
speed, set speed will be cancelled.
1) Cruise control switch is part of multifunction switch
mounted on steering column. To operate cruise control system, turn
ignition on. Turn cruise control switch to ON position. Ensure switch
indicator light comes on.
NOTE: Speed will not set beyond system limit of 90 MPH.
2) With cruise control switch in ON position, drive vehicle
between 25 and 90 MPH. Press and release SET button. Vehicle speed
should stay at set speed. Instrument cluster cruise indicator light
should come on. To increase set speed, turn control switch to RESUME
position and hold until new set speed is reached.
3) To lower set speed, press SET button and hold until new
set speed is reached. To return to set speed after cancellation, move
resume switch from ON to OFF position. Vehicle speed should return to
previous setting before cancellation. Set speed should cancel when any
of the following occurs:
* Brake pedal is pressed.
* Clutch pedal is pressed.
* Transmission is shifted to Neutral or Park.
* Cruise control main switch is turned off.
* Ignition switch is turned off.
SELF-DIAGNOSTICS
1) Self-diagnostics should be performed when cruise control
cancels without the driver using normal cancel modes. Diagnosis
connector is located on right side of fuse box. Use analog voltmeter
or Multi-Use Tester (MB991341) for code retrieval.
2) Use multi-use tester according to operating instructions
provided with tester. Connect leads of analog voltmeter between cruise
control terminal and ground terminal of self-diagnostic connector. See
Fig. 6 . Read voltmeter needle sweeps to determine trouble code.
NOTE: On 1991 models, codes No. 13, 14, 15, 16 and 17 will be
displayed whether malfunction is present or not.
3) Once trouble codes have been displayed, see SELF-
DIAGNOSTIC CODE CHART to determine appropriate CIRCUIT TEST. See
Fig. 7 or 8.
4) To clear trouble codes, either disconnect battery cable or
turn ignition on. Turn main cruise control switch and set switch to ON
position. Within one second turn resume switch to ON position.
5) Hold stoplight switch and cruise control switch in ON
position for more than 5 seconds. Verify codes are cleared.

CRUISE CONTROL SWITCH TESTS
Main, Set & Resume Switches (1991)
1) Disconnect 6-pin cruise control switch connector. See
Figs. 17 -21. With main switch in ON position, continuity should be
present between terminals No. 3 and 6 of cruise control switch
connector. With set switch in ON position, continuity should be
present between terminals No. 1 and 2.
2) With resume switch in On position, continuity should be
present between terminals No. 2 and 4, and 3 and 6. If continuity is
not present, replace cruise control switch.
Set & Resume Switches (1992)
1) Remove lower steering column cover. Disconnect 2-pin
switch connector. Operate and test switch. When cancel switch is
operated, continuity should be present between terminals No. 1 and 2.
Zero ohms resistance should be indicated.
2) When resume switch is operated, 820 ohms resistance should
be present between terminals No. 1 and 2. When set switch is operated,
2700 ohms resistance should be present between terminals No. 1 and 2.

INTRODUCTION TO MOTORIST ASSURANCE PROGRAM (MAP)
OVERVIEW OF MOTORIST ASSURANCE PROGRAM
The Motorist Assurance Program is the consumer outreach
effort of the Automotive Maintenance and Repair Association, Inc.
(AMRA). Participation in the Motorist Assurance Program is drawn from
retailers, suppliers, independent repair facilities, vehicle
manufacturers and industry associations.
Our organization's mission is to strengthen the relationship
between the consumer and the auto repair industry. We produce
materials that give motorists the information and encouragement to
take greater responsibility for their vehicles-through proper,
manufacturer-recommended, maintenance. We encourage participating
service and repair shops (including franchisees and dealers) to adopt
(1) a Pledge of Assurance to their Customers and (2) the Motorist
Assurance Program Standards of Service. All participating service
providers have agreed to subscribe to this Pledge and to adhere to the
promulgated Standards of Service demonstrating to their customers that
they are serious about customer satisfaction.
These Standards of Service require that an inspection of the
vehicle's (problem) system be made and the results communicated to the\
customer according to industry standards. Given that the industry did
not have such standards, the Motorist Assurance Program successfully
promulgated industry inspection communication standards in 1994-95 for
the following systems: Exhaust, Brakes, ABS, Steering and Suspension,
Engine Maintenance and Performance, HVAC, and Electrical Systems.
Further, revisions to all of these inspection were recently published.
Further, revisions to all of these inspection communication standards
are continually republished. In addition to these, standards for Drive
Train and Transmissions have recently been promulgated. Participating
shops utilize these Uniform Inspection & Communication Standards as
part of the inspection process and for communicating their findings to
their customers.
The Motorist Assurance Program continues to work
cooperatively and proactively with government agencies and consumer
groups toward solutions that both benefit the customer and are
mutually acceptable to both regulators and industry. We maintain the
belief that industry must retain control over how we conduct our
business, and we must be viewed as part of the solution and not part
of the problem. Meetings with state and other government officials
(and their representatives), concerned with auto repair and/or
consumer protection, are conducted. Feedback from these sessions is
brought back to the association, and the program adjusted as needed.
To assure auto repair customers recourse if they were not
satisfied with a repair transaction, the Motorist Assurance Program
offers mediation and arbitration through MAP/BBB-CARE and other non-
profit organizations. MAP conducted pilot programs in twelve states
before announcing the program nationally in October, 1998. During the
pilots, participating repair shops demonstrated their adherence to the
Pledge and Standards and agreed to follow the UICS in communicating
the results of their inspection to their customers. To put some
"teeth" in the program, an accreditation requirement for shops was
initiated. The requirements are stringent, and a self-policing method
