PARKING BRAKE ADJUSTMENT
To adjust parking brake, perform the following steps:

2.
Turn “OFF” engine and place transmission lever in “NEUTRAL.” Turn ignition switch to “ON” position.
Move parking brake switch to “UNLOCKED” position.
FRONT AXLE SERVICE BRAKES
Checking clearance between brake pad and
brake disc in the front axle.
1.
Locate the pinion adjusting bolt in the
upper part of the differential housing.
2.
Remove lock bolt (2, Figure 92) and
bracket (1).
3.
Rotate the square pinion adjusting bolt (3,
Figure 92) in counter clockwise direction
until it stops. At this time the clearance of
brake disk is “0”.
4.
Rotate adjusting bolt (3, Figure 92)
clockwise four turns (0.25 mm / rotation) to
set the clearance to 1 mm (0.4 in).

FRONT AXLE PARKING BRAKE
EMERGENCY RELEASE
1.
Locate parking brake release bolt on the
lower section on both sides of the housing.
2.
Loosen lock nut (4, Figure 92) from
adjusting bolt (5).
3.
Tighten adjusting bolt (5, Figure 92) until it

The initial setting of adjusting bolt is 47 mm and
should be readjusted to this length and lock nut
tightened after towing is complete.
REAR AXLE SERVICE BRAKE
There are three adjusting bolts per side at 120° intervals for the rear axle brake adjustment. All three must
be adjusted for proper operation. The adjusting procedure is same as the front brake adjustment method
and must be repeated for both sides.
