ROTORS
Determine the need to recondition based upon individual rotor
conditions that follow. Friction material replacement does not require
rotor reconditioning unless other justifications exist. DO NOT
recondition new rotors unless they are being pressed or bolted onto an
existing hub. It is not necessary to replace rotors in axle sets.
However, when replacing or reconditioning a rotor due to the
conditions that follow, you may suggest reconditioning of the other
rotor on the same axle to eliminate uneven braking behavior.
Determine the need to replace based upon the individual rotor
conditions that follow. Reconditioning is defined as machining and
block sanding, or block sanding only. Block sanding is defined as
using 120-150 grit sandpaper with moderate to heavy force for 60
seconds per side. Always wash rotors after servicing or before
installing.

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.

3) Tighten lock nut, and ensure brake pedal height is within
specification. Start engine to evacuate brake booster chamber. Stop
engine, and apply brake several times to remove vacuum from brake
booster.
4) Using hand pressure, depress brake pedal to measure free
play before resistance is felt. Free play distance for all models is
0.10-0.31" (3-8 mm). If distance is not within specification, it is
probably caused by excessive play between the brake pedal arm and the
clevis pin. Check and replace as necessary.
5) Start engine and apply 110 lbs. (490 N) of pressure to
brake pedal. With the carpet pulled back, measure the distance between
the brake pedal and the floorboard. If the distance is not 3.1-3.5"
(80-90 mm) check for air in brake hydraulic system, brake adjustment
or defective parking brake component or adjustment. Adjust or repair
as necessary.
LOAD-SENSING PROPORTIONING VALVE (LSPV)
Montero
1) Park vehicle on level surface. Remove excess weight from
vehicle. Make sure the lever is all the way towards the valve side.
Measure length of entire spring. See Fig. 1.
If spring length is not within specification, adjust spring
support until correct length is obtained. See LSPV SPRING LENGTH
table.

times then switch the engine off.
2) Remove the master cylinder from the brake booster making
sure the push rod is not disturbed and the brake pedal is not
depressed after master cylinder removal.
3) Using a Vernier Caliper and Block Gauge, measure the
thickness of the block gauge and add .366" (9.3 mm) to the gauge
thickness and set the caliper to this dimension. See Fig. 4.

4) Check the push rod position with vernier caliper set to
the calculated dimension. Specification range .362"-.370" (9.2-9.4
mm). See Fig. 5.

(62-73 kPa) of vacuum applied to the brake booster.
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.

REAR BRAKE SHOES
Fully release parking brake and depress brake pedal several
times to center shoes and adjust brake shoe clearance. Adjust shoes so
brake shoes lightly contact brake drum. Adjust parking brake, and
check pedal travel. Rotate brake drum to verify free movement.
STOPLIGHT SWITCH
Loosen lock nut, and adjust switch-to-pedal arm clearance to
0.02-0.04" (0.5-1.0 mm). Tighten lock nut. DO NOT depress master
cylinder push rod during stoplight switch adjustment.
