steps.
(a) Remove the adjusting hole plug in the backing plate.
(b) Insert a screwdriver through the hole in the backing plate,
and hold the automatic adjusting lever away from the ad-
justing bolt.

INSTALLATION
Installation is in the reverse order of removal (See page
BR−45).
NOTICE:
Apply lithium soap base glycol grease and high tempera-
ture grease to the parts indicated by the arrows (See page
BR−44).
1. ADJUST BELLCRANK
(a) Lightly pull the bellcrank in direction A until there is no
slack at part B.
(b) In this condition, turn the adjusting bolt so that dimension
C will be 0.4 − 0.8 mm (0.016 − 0.031 in.).
(c) Lock the adjusting bolt with the lock nut.
(d) Connect the parking brake cable to the parking brake bell-
crank and install the clip.
(e) Install the tension spring.
2. CHECK OPERATION OF AUTOMATIC ADJUSTING
MECHANISM
(a) Move the parking brake lever of the front shoe back and
forth. Check that the adjuster turns.
If the adjuster does not turn, check for incorrect installation of
the rear brakes.
(b) Adjust the adjuster length as short as possible.
(c) Install the brake drum.
(d) Pull the parking brake lever all the way up until a clicking
sound can no longer be heard.
3. CHECK CLEARANCE BETWEEN BRAKE SHOES AND
DRUM (See page BR−43)

4WD: 1,050 kg (2,315 lb)
2. INSTALL LSPV GAUGE (SST) AND BLEED AIR
SST 09709−29017
3. RAISE FRONT BRAKE PRESSURE TO 7,845 kPa (80
kgf/cm
2, 1,138 psi) AND CHECK REAR BRAKE PRES-
SURE
Rear brake pressure:
5,325 ± 490 kPa (54.3 ± 5 kgf/cm
2, 772 ± 71 psi)
HINT:
The brake pedal should not be depressed twice and/or returned
while setting to the specified pressure. Read the value of rear
brake pressure after holding the specified fluid pressure for 2
seconds. If the brake pressure is incorrect, adjust the fluid pres-
sure.

4. IF NECESSARY, ADJUST FLUID PRESSURE
(a) Loosen the lock nut.
(b) Adjust the length of the No.2 shackle.
Low pressure: Lengthen A
High pressure: Shorten A
Initial set: 120 mm (4.72 in.)
Adjustment range: 114 − 126 mm (4.49 − 4.96 in.)
HINT:
One turn of the nut changes the fluid pressure as shown in the
following specification.
7.5 kPa (0.77 kgf/cm, 11 psi)
(c) Torque the lock nut.
Torque: 25 N·m (250 kgf·cm, 18 ft·lbf)
(d) If the pressure cannot be adjusted by the No.2 shackle,
raise or lower the valve body. (2WD shown, for 4WD refer
to component illustration on next page.)
Low pressure−Lower body
High pressure−Raise body
(e) Torque the nuts.
Torque: 13 N·m (130 kgf·cm, 9 ft·lbf)
(f) Adjust the length of the No.2 shackle again.
If it cannot be adjusted, inspect the valve housing.
5. IF NECESSARY, CHECK VALVE BODY
(a) Assemble the valve body in the uppermost position.
HINT:
When the brakes are applied, the piston will move down about
0.8 mm (0.03 in.). Even at this time, the piston should not make
contact with or move the load sensing spring.
(b) In this position, check the rear brake pressure.
Front brake pressure
kPa (kgf/cm2, psi)
Rear brake pressure
kPa (kgf/cm2, psi)
1,960 (20, 285)1,960 (20, 285)
