Fig. 17 Free Travel Adjustment
The correct brake pedal free travel should be set to 7/8"
- 1 1/8" (2.2 - 2.9 cm).
Press the brake pedal aggressively 4 - 6 times to estab-
lish known free travel.
All brake tests must be done in a safe location
with regard for the safety of all personnel.
In a safe location free from people and vehicles, drive
the vehicle at reduced speed and apply the brakes
aggressively. As the brakes adjust and stop the vehicle
effectively, start driving at maximum speed and brake
aggressively 10 times.
At the spherical nut, adjust the free travel as noted
above.
Drive again and brake aggressively 10 times.
Repeat the previous steps until the pedal free travel
does not change during the aggressive braking.
Check to see that the clevis pins attaching the brake
cables to the brake levers are loose. If they are not loose,
inspect system again and correct as required. if the
clevis pins are loose, tighten jam nut to 10 - 11 ft. lbs.
(14 - 15 Nm) at the spherical nut.
The parking brake latching force can be checked as verifi-
cation after setting brake pedal free travel. To check park-
ing brake latching force, place a 'bathroom' scale on the
service and parking brake pedals. Using both feet press
the scale down against the parking brake pedal until it
latches. The parking brake should latch between 65 and
75 lbs. (29 - 34 kg) indicated on the scale.
Jam Nut
Perform the Periodic Brake Performance Test as
described and return the vehicle to service if brake per-
formance is satisfactory.

Brake Drum Removal and Installation

lated nut (2) and the cotter pin (3). Brake Assembly

tap the drum with a plastic faced hammer to loosen it
from the axle shaft or use drum puller (P/N 15947-G1).
