Brake Adjustment
Figure 9. Checking Brake Clearance
Figure 10. Adjusting Brake Clearance
NOTE:
Compressing the brake spring too tight will
increase the effort to move the steer handle to the
operating position.
6.
To adjust the brake switch loosen the nut re-
taining the switch actuator and adjust the ac-
tuator plate up or down as necessary to obtain
the proper adjustment. Tighten the nut retain-
ing the actuator plate. On all units the actua-
tor is properly adjusted when the brake switch
slightly opens as the brake is starting to apply.
7.
Install the drive unit compartment hood.
8.
Lower the lift truck so the drive wheel is on the
floor. Connect the battery and test the operation
of the lift truck prior to returning the lift truck to
service. The brakes should be capable of holding
on a 10% slope with a rated load. The unit should
also be able to operate without any brake drag
when the handle is in the operating position.

NOTE:
Adjust the brake shoes before attempting to
adjust the service and parking brake linkage.
1.
Raise the drive wheel off the floor. Block the lift
truck see the section Periodic Maintenance
8000 SRM 281. Refer to WARNINGS in Repairs
- General.
2.
Disconnect the battery connector.
3.
Remove the drive unit compartment hood to ac-
cess the brakes.
4.
Discharge the traction motor controller capaci-
tor. Refer to WARNINGS in Repairs - General.
5.
Make certain the hand brake levers are released.
Release the parking brake. Install a 0.127 mm
(0.005 in.) feeler gauge between the lower brake
shoe lining and brake drum at the point of least
clearance. See Figure 9. The feeler gauge should
slide freely. If an adjustment is necessary, loosen
the setscrew and turn the adjusting screw. Turn
the screw clockwise to decrease the clearance.
Turn the screw counterclockwise to increase the
clearance between the brake shoe and drum. Af-
ter the correct adjustment is obtained, tighten
the setscrew. See Figure 10.
6.
Adjust the upper brake shoe assembly. Loosen
the setscrew and turn the adjusting screw. Turn-
ing the adjusting screw counterclockwise will
decrease the clearance between the brake drum
and brake shoes. Adjust to obtain a 0.127 mm
(0.005 in.) clearance. Tighten the setscrew.
7.
Have an assistant operate the hand brake levers
and check to see that the brakes are engaged
when hand pressure is applied to the levers.
