Brake Maintenance

Inspecting the Brakes

Service Interval: Every 100 hours
Brakes are a critical safety component of the machine. As
with all safety components, they should be closely inspected at
regular intervals to ensure optimum performance and safety.
The following inspections should be done every 100 hours:
•
Inspect the brake shoes and pads for wear or damage.
If the thickness of the lining of the brake shoe or pad is
less than 1.6 mm (1/16 inch), replace the brake shoe(s),
pad(s), or both.
•
Inspect the backing plate and other components for signs
of excessive wear or deformation. If any deformation is
found, the appropriate components must be replaced.
•
Check the brake fluid level; refer to
Fluid Level (page 20).

Service Interval: Every 200 hours
1. Remove the hand grip from the parking-brake lever
(Figure 47).

2. Loosen the set screw securing the brake-adjustment
knob to the parking-brake lever
3. Rotate the brake-adjustment knob until a brake-lever
force of 133 to 156 N-m (30 to 35 ft-lb) is required to
set the parking-brake lever
Note: If you rotated the brake-adjustment knob the
full travel of the adjuster and cannot attain the lever
force of 133 to 156 N-m (30 to 35 ft-lb) that is required
to set the parking-brake lever, perform the procedure
for adjusting the brake cables; refer to

2. Loosen the set screw
brake-adjustment knob to the parking-brake
lever, release the parking brake, and loosen the
brake-adjustment knob.
3. At the bottom of the machine, loosen the rear-jam nut
for the threaded adjuster of the parking-brake cable
4 turns (Figure 48).

set the parking-brake lever.
•
If you cannot adjust the brake-adjustment knob by
loosening it and set the parking-brake lever with a
a force of 133 to 156 N-m (30 to 35 ft-lb); perform
the following:
A. Loosen the forward-jam nut
the threaded adjuster of the parking-brake
cable 1 turn.
B. Tighten the rear jam nut
C. Rotate the brake-adjustment knob
until a force of 133 to 156 N-m (30 to 35 ft-lb)
is required to set the parking-brake lever.
D. Repeat steps
to attain the parking brake force between 133
to 156 N-m (30 to 35 ft-lb).
