PARKING BRAKE
ADJUSTMENT
To adjust parking brake, perform the following steps:
1. Jack up machine enough to allow tires to rotate freely.
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 122) and bracket (1).
3. Rotate the square pinion adjusting bolt (3, Figure 122)
in counter clockwise direction until it stops. At this time
the clearance of brake disk is “0”.
4.
Rotate adjusting bolt (3, Figure 122) clockwise four turns
(0.25 mm / rotation) to set the clearance to 1 mm (0.4 in).
5. Install lock bracket (1, Figure 122) and bolt (2).
Repeat steps 1-5 for other side.
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 122) from adjusting bolt (5).
3. Tighten adjusting bolt (5, Figure 122) until it stops. This
will manually release the parking brake so that the
drive shaft will be free to turn.
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
.
