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. See
'Adjusting Brake Pedal Free Travel' on page M-14. 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 Flowchart (Ref Fig. 5 on
page M-4). Then, perform the Periodic Brake Perfor
mance Test to evaluate system performance. Based on
the results of the inspection and tests, refer to the Trou
bleshooting Table (Ref Fig. 6 on page M-6) to evaluate
symptoms and repairs. If required, disassemble 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' on page M-14.
CAUTION
Satisfactory brake performance does
not eliminate the need for routine brake
testing and inspection as shown on the Periodic Service Sched
ule in Section A. Continued proper brake operation depends on
periodic maintenance.
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 and that a 1/4 - 3/8" (6 - 9.5 mm) gap
exists between the brake pedal arm and the setscrew
heads of the kick-off cam (Ref Fig. 7 on page M-8).
Replace or adjust the pedal bumper if required. See
'Pedal Bumper Adjustment' on page M-20.
2.
Check brake pedal return.
Apply the brake pedal and release. Check that the
brake pedal arm rests against the pedal bumper
when released. Check that the torsion spring is
hooked around both the pedal and the frame and is in
good condition. If the pedal does not return fully or is
sluggish, the brake pedal bushings and pivot bolt
1/4" - 3/8" (6 - 9.5 mm) Diameter
Drill or Bolt Must Pass
Through Gap
Adjust At Bumper If Needed

should be inspected (Ref Fig. 8 on page M-8).
Replace pedal, spring, bushings and bolt as required.
See 'Brake Pedal Removal and Installation' on page M-19.
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 adjust
ing properly.
