the tension in the brake linkage. The Parking Brake can
be released by two methods:
1. Depressing the service brake, which permits the
spring loaded Parking Brake pedal to return to its orig-
inal position, disengaging the latch arm from the catch
bracket. This is the preferred method which minimizes
wear on components.
2. Pressing the accelerator pedal rotates the kick-off
cam which forces the pedal latch arm to move away
from the catch bracket. The spring loaded Parking
Brake pedal returns to its original position, releasing
the brake.
Kick-Off Actuating Linkage
The kick-off actuating linkage may require periodic
adjustment to compensate for the normal wear.
Replacement of any linkage components will also
require an adjustment.
TROUBLESHOOTING AND
INSPECTION
New Vehicles
A new vehicle will undergo an initial break-in of compo-
nents including brake cables and brake shoes. In this
break-in period, it is not uncommon for the brake pedal
free travel (and the effort required to latch the parking
brake) to change. The timing of this change varies with
terrain and the driving habits of the operator(s). When
this occurs, the brake linkage should be adjusted.
“Adjusting Brake Pedal Free Travel” on Page M 8 After this
initial period, no further adjustments should be required
until routine maintenance is scheduled.
Troubleshooting and Inspection Procedures
To troubleshoot the mechanical brake system, inspect
the brake pedal and linkage to find worn or damaged
parts per the Troubleshooting Table. Then, perform the
Periodic Brake Performance Test to evaluate system
performance. Based on the results of the inspection and
tests, refer to the Troubleshooting Table in Section S to
evaluate symptoms and repairs. If required, disassem-
ble the wheel brake to locate and correct internal faults.
Instructions for removal or replacement of parts and
adjustments referred to in this section of the manual are
described in detail under ‘MAINTENANCE AND
REPAIRS’ .
Satisfactory brake performance does not eliminate the
need for routine brake testing and inspection as shown
on the Periodic Service Schedule in Section A. Contin-
ued proper brake operation depends on periodic main-
tenance.
Brake Pedal and Linkage Inspection
1.
Inspect brake pedal return bumper.
Be sure that the brake pedal is contacting the pedal
return bumper when released, that the bumper is in
good condition. (Ref. Fig. 3).
Fig. 3 Brake Pedal Inspection
2.
Check brake pedal return.
Apply the brake pedal and release. Check that the
brake pedal arm rests against the pedal bumper when
released. If the pedal does not return fully or is slug-
gish, the brake pedal bushings and pivot bolt should
be inspected (Ref. Fig. 3).
3.
Check the brake pedal free travel.
Brake pedal free travel is the distance the pedal
moves from rest to the point at which the brake shoes
first contact the brake drums. This should not be con-
fused with the light resistance that is felt as the brake
pedal is depressed enough to remove slack from the
compensator and cables. Too much pedal free travel
may indicate wheel brakes not adjusting, wear in the
cables and linkages or initial break-in of components.
Not enough pedal free travel may indicate improper
adjustment of the wheel brake or the brake linkage.
Either condition can prevent the brakes from adjusting
properly.
