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.

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.
TESTING

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\

pressure at specified pressure range (split point). See
SPLIT POINT PRESSURE SPECIFICATIONS table.

REMOVAL & INSTALLATION
FRONT DISC BRAKE PADS
CAUTION: DO NOT remove or contaminate special grease coating on lock
pins.
Removal & Installation (Except 3000GT AWD)
1) Raise and support vehicle. Remove front wheels. Remove
lower lock pin or sleeve bolt. See Figs. 13-15. Lift caliper body
upward. Support caliper aside. Remove shims and pads from support
mounting. Remove pad clips.
2) If installing new pads, compress piston to bottom of bore.
Install retaining clips, pads and shims. Start engine and depress
brake pedal several times to expand caliper piston. Check brake fluid
level.

Removal & Installation (3000GT AWD)
1) Raise and support vehicle. Remove front wheels. Remove
clip, brake pad retaining pins and spring. See Fig. 17. Remove shims
and pads from caliper. Keep track of location of shims for reassembly.
2) Compress caliper pistons fully in bores. Install shims on
brake pads. Install brake pads. Install spring clip, pad retaining
pins and clip. Start engine and depress brake pedal several times to
expand caliper piston. Check brake fluid level.
