INSPECT THE PARKING
BRAKE
Do not use a brake drum that is worn beyond
its service limits. A drum worn beyond its
service limits could fail and cause loss of brakes
resulting in severe bodily injury and/or property
damage.
INSPECT THE SERVICE BRAKE
Brake Shoes
NOTE: The brake band should removed to accurately
measure the lining.
Measure the brake shoe lining at the thinnest point . If this is
1/16-inch or less then the brake band must be replaced.
Brake Drum
The service limit for the outside diameter of the brake drum is
5.85 inches. The service limit for runout is 0.010 inches.
If the brake drum is grooved or worn beyond the service limits
then the brake drum must be replaced.
The parking brake system uses the same components as the
service brake with the exception of the parking brake locking
mechanism on the brake pedal..
Inspect the locking tab on the frame as well as the brake pedal
cogs for any signs of excessive wear.
If any signs of excessive wear is found then the parts should
be replaced.
ADJUST THE PARKING BRAKE
The parking brake uses the same components as the service
brake. There is no independent adjustment of the parking brake.

brakes are asbestos free.
However, there is the possibility that the original
brakes were replaced with aftermarket parts
containing asbestos. Since this possibility exists, all
brake parts should be handled as if they contain
asbestos. Refer to Appendix C for recommended
handling precautions.

position, then remove the key.
2. Place the forward-reverse switch in the center
“OFF” position.

4. Place blocks under the front wheels to prevent
vehicle movement.
