PARKING BRAKE ADJUSTMENT

1. Disengage the PTO, stop the engine, block the front
wheels, remove the ignition key, and engage the
parking brake.
2. Jack up the rear of the machine and secure with
jackstands. Remove both drive tires.
3. With the parking brake engaged, measure the com-
pressed spring length (see Figure 34). The spring
should be 2-1/8" - 2-1/4" (5,4 - 5,7 cm) long when
compressed.
4. If the spring does not measure 2-1/8" - 2-1/4" (5,4 -
5,7 cm), release the parking brake and turn the
adjustment nut (B) to adjust the spring length
5. Engage the parking brake and remeasure the spring
length. Continue to adjust the nut as required.
CAUTION
Do not adjust the spring to be shorter than
2-1/8" (5,4 cm) when compressed. This may
damage the brake caliper.
6. With the parking brake engaged, adjust the set collar
position until 3/16" (4,7 mm) gap is measured
between the set collar and brake link.
7. Reinstall the drive tires. Torque the lug bolts to
85-95 ft/lbs. (115-129 Nm). Remove the jackstands
from under the machine.
