3000GT
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.

Removal & Installation
1) Drain master cylinder. Remove cotter pin, washer and
clevis pin. Disconnect push rod from clutch pedal. Remove and plug
hydraulic line at clutch master cylinder.
2) Remove retaining nuts, clutch master cylinder and gasket.
To install, reverse removal procedure. Apply grease to clevis pin
before installing. Fill reservoir and bleed clutch system. See
BLEEDING CLUTCH HYDRAULIC SYSTEM .
CLUTCH RELEASE CYLINDER
Removal & Installation
Remove and plug hydraulic line at release cylinder. Remove
cylinder-to-transmission bolts. Remove clutch release cylinder. To
install, reverse removal procedure. Apply grease to push rod-to-
release fork contact area. Bleed clutch system. See
BLEEDING CLUTCH HYDRAULIC SYSTEM .
BLEEDING CLUTCH HYDRAULIC SYSTEM
Attach hose to bleeder fitting located on clutch release
cylinder, next to hydraulic line. Submerge other end of hose in
container half full of clean brake fluid. Fill reservoir with brake
fluid. Open bleeder fitting. Have assistant press clutch pedal to full
release position. Close bleeder fitting. Release clutch pedal. Repeat
until air bubbles no longer emerge from hose. Refill reservoir.
OVERHAUL
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.

CLUTCH RELEASE CYLINDER
Disassembly
Remove valve plate and spring. See Fig. 7. Remove push rod
and boot. Cover piston assembly opening with a rag. Slowly apply air
pressure to hydraulic line opening to force piston from body.
Inspection & Reassembly
Inspect components for corrosion, scoring or damage. Replace
if necessary. Apply brake fluid to components during reassembly. To
reassemble, reverse disassembly procedure. Ensure piston moves freely
in bore.
