Stop Light Switch Circuit
CIRCUIT DESCRIPTION
The purpose of this circuit is to prevent the engine from stalling, while driving in lock−up condition, when
brakes are suddenly applied.
When the brake pedal is operated, this switch sends a signals to the ECM. Then the ECM cancels operation
of the lock−up clutch while braking is in progress.

PARKING BRAKE LEVER
ON−VEHICLE INSPECTION
1. CHECK PARKING BRAKE LEVER TRAVEL
Pull the parking brake lever all the way up, and count the num-
ber of clicks.
Parking brake lever travel at 196 N (20 kgf, 44.1 lbf):
11 − 17 clicks
2. 2WD:
IF NECESSARY, ADJUST PARKING BRAKE
HINT:
Before adjusting the parking brake, make sure that the rear
brake shoe clearance has been adjusted.
(a) Tighten the adjusting nut until the travel is correct.
Then tighten the lock nut.
(b) After adjusting the parking brake, confirm that the rear
brakes are not dragging.
3. 4WD:
IF NECESSARY, ADJUST PARKING BRAKE
HINT:
Before adjusting the parking brake, make sure that the rear
brake shoe clearance has been adjusted.
(a) Tighten 1 of the adjusting nuts of the intermediate lever
while loosening the other one until the travel is correct.
Tighten the 2 adjusting nuts.
(b) After adjusting the parking brake, confirm that the bell-
crank stopper screw comes into contact with the backing
plate.

INSTALLATION
Installation is in the reverse order of removal (See page
BR−40).
NOTICE:
Apply lithium soap base glycol grease and high tempera-
ture grease to the parts indicated by the arrows (See page
BR−39).
1. CHECK OPERATION OF AUTOMATIC ADJUSTER
MECHANISM
(a) Move the parking brake lever of the rear shoe back and
forth, as shown. Check that the adjusting bolt turns.
If the adjuster does not turn, check for incorrect installation of
the rear brakes.
(b) Adjust the adjuster length to the shortest possible
amount.
(c) Install the drum.
(d) Pull the parking brake lever all the way up until a clicking
sound can no longer be heard.
2. CHECK CLEARANCE BETWEEN BRAKE SHOES AND
DRUM
(a) Remove the drum.
(b) Measure the brake drum inside diameter.
(c) Measure the distance between brake shoes. Check that
the difference between the diameters is the correct shoe
clearance.
Shoe clearance: 0.6 mm (0.024 in.)
If incorrect, check the parking brake system.
3. FILL BRAKE RESERVOIR WITH BRAKE FLUID AND
BLEED BRAKE SYSTEM (See Page BR−4)
4. CHECK FOR LEAKS

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

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)
3,920 (40, 570)2,352 ± 196 (24 ± 2, 342 ± 28.5)
6,860 (70, 997.5)2,940 ± 343 (30 ± 3.5, 427.5 ± 50)
If the measured value is not within the standard, replace the
valve body.
