Assembly Adjustment (Traveling Device)
6. Braking force
[NOTICE]

Detach the connector of the inter-axle differential
lock solenoid valve inside the pneumatic unit in the
right center of the vehicle beforehand.

The braking force to be checked is the difference
between the measured value when the brake pedal
is depressed and the one when the pedal is not
depressed.

After adjustment, return the connector for the
inter-axle differential lock solenoid valve to the
original position.
6.1 Parking brake force
1. Must be 20% of the vehicle weight (including 1
person aboard) at least.
Check that the front and rear braking forces are
80.9 kN {8259 kgf} (18208 lbf) or more.
6.2 Service brake force
1. The difference in the braking force between the
right and left wheels must be 6% of the axle load
or less.
Check that it is not greater than 5.9 kN {608 kgf}
(1340 lbf) (according to the type approval testing
standard).
2. Check that the sum of the braking force is 40% of
the vehicle weight at least.
Check that the front (1st and 2nd axles) braking
force is 112.6 kN {11487 kgf} (25324 lbf) or more.
Check that the rear (3rd and 4th axles) braking
force is 54.6 kN {5563 kgf} (12264 lbf) or more.
6.3 Auxiliary operating brake (aux. brake) force
1. Check that the sum of the braking force of the
auxiliary operating brake (aux. brake) is 35% of
the vehicle weight at least.
Front + rear = 141.6 kN {14453 kgf} (31863 lbf)
