Parking Brake Adjustment - Ferris IS4000Z/D31 Operator's Manual

PARKING BRAKE ADJUSTMENT

1. Disengage the PTO, stop the engine, block the front
wheels, remove the ignition key, and engage the
parking brake.
2. Remove both fuel tanks.
3. Locate the upper brake spring (A, Figure 27).
4. With the parking brake engaged, measure the com-
pressed spring length. The spring should be
2" to 2-1/8" (5,0cm - 5,4cm) when compressed.
5. If the spring is not within this range, jack up the rear
of the machine and secure with jackstands. Remove
both drive tires.
6. Locate the lower brake spring (A, Figure 28), adjust-
ment nuts (B, Figure 28) and adjustment link (C,
Figure 28).
7. Release the parking brake and turn the adjustment
nuts to compress or release the upper spring. Lock
the nuts against the adjustment link (C, Figure 28).
NOTE: Do not adjust the upper brake spring to be short-
er than 2" when compressed. This may damage the
caliper case.
If this does not correct the braking problem, see
your dealer.
