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.
