NOTE: For adjustment information on brake pedal height, free play,
parking brake and stoplight switch, see BRAKE SYSTEM article.
WHEEL SPEED SENSOR (WSS)
NOTE: Rear WSS gap adjustment information is not available from
manufacturer.
Front WSS-To-Rotor Gap Adjustment
1) Raise and support vehicle. Remove wheel(s). Inspect senso\
r
pole piece for damage. Repair if necessary. If sensor pole piece is
okay, check WSS-to-rotor gap.
2) Using a feeler gauge, check clearance between sensor pole
and rotor tooth surface. See Fig. 1. Front WSS sensor clearance should
be .008-.390" (0.2-1.0 mm). If clearance is not as specified, loosen
sensor mounting bolt. Adjust sensor position until clearance is within
specification. Tighten sensor mounting bolt to specification. See
TORQUE SPECIFICATIONS .

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.

BRAKE BOOSTER PUSH ROD

POWER BRAKE BOOSTER
System Check
1) Run engine for 1-2 minutes. Shut engine off, and depress
brake pedal several times with normal pressure. If pedal height
gradually becomes higher with successive applications, power brake
booster is okay. If pedal height remains steady, power brake booster
is not operating properly, go to next step.
2) With engine stopped, depress brake pedal repeatedly until
pedal height no longer falls. Hold brake pedal down, and start engine.
If pedal moves downward slightly, power brake booster is okay. If
pedal height does not change, power brake booster is not operating
properly, go to next step.
3) With engine running, press and hold brake pedal. Shut off
engine. Hold brake pedal for 30 seconds. Brake pedal height should not
change. If pedal rises, power brake booster is not operating properly,
go to next step.
4) If brake booster operation is not as specified in each
step, disconnect vacuum hose at brake booster and check for sufficient
vacuum with engine running. Also check brake booster check valve
operation. Repair or replace as necessary.
Check Valve Inspection
Remove vacuum hose from power brake booster. Do not remove
check valve from hose. Check valve should hold vacuum in one direction
and allow air to pass in other direction.
LOAD-SENSING PROPORTIONING VALVE (LSPV)
Montero
1) Before diagnosing Load-Sensing Proportioning Valve (LSPV)\
,
ensure all other brake components are operating properly. When all
other brake system components are determined to be okay, ensure LSPV
spring length is within specification. See Fig. 1. See LOAD-SENSING
PROPORTIONING VALVE (LSPV) under ADJUSTMENTS.
2) After spring length is determined to be within
specification, connect pressure gauges to input and output ports of
LSPV. See Fig. 7. Bleed brake system. See BLEEDING BRAKE SYSTEM.

3) With vehicle unloaded at correct ride height and LSPV
spring correctly adjusted to 8.9" (227 mm), slowly depress brake pedal\
