Section 3 • Repair Procedures
Proper brake action is essential to safe machine
operation. The machine uses drive motor
regenerative braking to slow and stop the
machine.
Spring applied electrically released individual
wheel brakes hold the machine once it has
stopped. The drive motor regenerative braking
should operate smoothly, free of hesitation and
jerking.
1 Block the steer wheels to prevent the machine
from rolling.
2 Disconnect the battery packs from the machine.
3 Remove the chassis cover fasteners from the
non-steer end of the chassis. Remove the
cover.
4 Tag and disconnect the electrical connector
from the brake.
5 Loosen the brake mounting fasteners in an
even pattern until all spring tension has been
relieved. Remove the fasteners.
6 Remove the brake from the drive motor.
Some parts may fall loose from the brake
assembly during removal. Refer to the following
illustrations to be sure the spring pattern is correct
and that the rest of the brake components are
assembled properly prior to installing the brake
onto the drive motor.
When installing the brake, torque the brake
mounting fasteners to 7.4 ft-lbs / 10 Nm.
