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.

and check fluid input and output pressures at LSPV. See
LSPV PRESSURE SPECIFICATIONS table.
4) Disconnect spring at support and pull spring and lever
toward support until spring length is 10.1" (257 mm). See Fig. 1.
Slowly depress brake pedal and check input and output pressures at
LSPV. See LSPV PRESSURE SPECIFICATIONS table. If fluid input pressure
is okay and output pressure is not within specification, replace LSPV
assembly. Remove gauges and bleed brake system.

3) Check facing of clutch disc for loose rivets, uneven
contact, deterioration, seizure or oil saturation. Measure distance
from clutch disc surface to head of rivet. Replace clutch disc if
distance is less than .012" (.30 mm). Replace worn or defective
components as necessary. See Fig. 4.
CAUTION: Install clutch disc with manufacturer's stamp mark (located
near hub of clutch disc) toward pressure plate.
Installation
1) Using a clutch alignment tool, install pressure plate and
clutch disc. If reusing pressure plate, ensure index marks are
aligned. Tighten bolts evenly in a crisscross pattern to
specification. See TORQUE SPECIFICATIONS . See Fig. 3.
2) Clean release bearing sliding surface. DO NOT clean

CLUTCH MASTER CYLINDER
NOTE: DO NOT disassemble piston assembly.
Disassembly
Remove piston stop ring, damper and push rod assembly. See
Fig. 6 . Remove piston assembly. Note position of reservoir band for
reassembly reference. Remove reservoir.
Inspection & Reassembly
Inspect components for corrosion, scoring or damage. Replace
if necessary. Apply brake fluid to components during reassembly. On
Montero, adjust clutch master cylinder push rod to 5.90" (150 mm). On
Montero Sport, push rod adjustment is correct after adjusting clutch
pedal free play and pedal height. See CLUTCH PEDAL FREE PLAY and
CLUTCH PEDAL HEIGHT under ADJUSTMENTS. To reassemble, reverse
disassembly procedure. Ensure piston moves freely in bore.
