MANUAL BRAKE
The manual brake uses a pull handle. With the foot
brake, it employs an automatic power brake that stops
the front wheels. Only when the truck has been
parked, can the manual parking brake be used.
Before adjusting the parking brake, test to confirm the
drive axle braking system functions properly:
1. Adjust the lock nut (item 5, Figure 29) so the
length is equal to 68 mm (2.7 in.). Tighten the
lock nut.
2. Turn the nut (item 7, Figure 29) to adjust the
parking brake’s pulling force to
147-196 N•m (108.4-144.6 lbf ft).
3. After the manual brake lever is correctly adjusted,
release the lever to release the brake.
4. Ensure that the parking brake is functioning
properly.
NOTE: Coat appropriate amount of lithium base
grease onto the guide rail (item 6, Figure 29) and
apply regularly.
