TIRES, BRAKES AND DRIVETRAIN
2-9
To check the park brake:
1. Sit in the driver’s seat and turn the key switch to ON.
2. With the seat belt on, put the directional switch in the
forward position and drive forward at a very slow
speed.
3. While truck is creeping forward, turn the key switch to
the off position.
4. The park brake should click on immediately after the
key switch is turned OFF, bringing the truck to an
abrupt stop. If this doesn’t happen, refer to “Park
Brake Maintenance”.
NOTE
This test can also be done on a ramp without having the
lift move, if your facility is so equipped. The ramp method
is less likely to flat-spot the tires.
NOTICE
Park Brake Installation and Mounting
1. Remove the dust cover (if applicable).
2. Remove the three socket head cap screws from the
top of the brake assembly to remove the mounting
plate.
3. Screw the mounting plate onto the motor using three
M8 hex bolts and lock washers.
4. Re-install the park brake onto the mounting plate
using the three socket head cap screws.
5. Using a feeler gauge, leave a gap of .034” (.86mm)
between the mounting plate and brake case. Loosen
the three hex bolts and adjust the air gap nuts as
necessary. It is important to measure this in at least 3
locations around the brake. The air gap should not
vary.
6. Replace dust cover (if applicable).
Park Brake Maintenance
• The brake surface must be free of debris and
contaminants.
• At certain intervals the air gap may need
readjustment. Refer to step 5 from “Park Brake
Installation and Mounting”.
• Excessive wear may make it necessary to readjust the
Power-On nuts to allow proper function. The rotor and
shaft will rotate freely 8-10° of the Power-On release.
Adjust the two Power-On nuts, shown in Figure 2-7,
as necessary.
• It is normal for brakes to become hot to the touch. The
brakes are insulation rated to 311° F (155° C).

DO NOT release or operate the truck if you are in
doubt about the effectiveness of the parking
brake system. Contact your Landoll service
representative for assistance.
