7.3.6 EMERGENCY/PARKING BRAKE ADJUSTMENT
Adjusting the Emergency/Parking Brake (HDi and HD
Models)
There are 8 positions on the hand brake lever. The cable
should be adjusted to have the 5th position (click) as fully
engaged with normal rm effort (extra effort required for
6th). Reaching into the vehicle to the band brake (with the
lever fully down), you should be able to grab the bottom
of the band and wiggle it back and forth on the drum. It
shouldn't feel tight. You should also be able to grab the metal
"J" bend at the end of the cable where the adjusting nut is
and move it up and down, essentially moving the band and
pins in the mounting bracket slots. This shouldn't feel tight
either. If the band is too tight it will drag and the operator
may experience a sluggish vehicle and notice smoke coming
from the engine compartment and an unpleasant smell, as the
band brake rubs against the drum. This will cause the band
to wear out prematurely. If the 5th position (click) does not
provide the full engagement with normal rm effort (extra
effort for the 6th) after checking the band brake as described
above, adjust the cable accordingly. Loosen jam nut at cable
and thread out as needed. Figure 7-19c.

Adjusting the Emergency/Parking Brake (Avengers and
Frontiers)
The emergency/parking brake system has been factory adjust-
ed to ensure proper braking effectiveness. However, before
the vehicle is used for the rst time, and after every 25 hours
of operation, the adjustment of the brake must be inspected.
The use of an improperly adjusted emergency/parking
brake is a serious hazard, and could lead to vehicle
damage or personal injury.
The hand brake lever should be adjusted such that when pulled
up rmly it is capable of holding the vehicle from rolling on
a grade. It should also ensure a good braking response when
applied to stop the vehicle during normal operation.
If the emergency/parking brake system is adjusted too
tight when the lever is in the down position, overheating
of the brake system will occur due to drag between brake
pads and brake discs.
Adjusting the Emergency/Parking Brake
1. Remove the rewall.
2. Ensure the parking brake lever is fully down.
3. Locate the 850-72 Parking Brake Adjustment Bracket
attached to the top of the transmission. Figure 7-20.
Adjust to remove any slack in the cable that may be
present between the brake lever, and the brake cams at
the emergency/parking brake calipers. This may require
physically pulling down on the equalizer at bar to ensure
all slack is eliminated. See Figure 7-21.
