Replacement and Wear of Park Brake Lock (All Models)
In the following procedure, you will be told how to replace the Park Brake Lock
assembly:
1. Park the vehicle on a clean flat surface and block the rear wheels to
prevent movement.
2. Turn the key off and place the forward/reverse switch in neutral.
3. Disconnect the main positive and negative terminals from the battery.
4. With the brake pedal in its fully extended position, remove the 1/2” bolt
and locknut from under the pedal.
5. Remove the pedal and park brake lock assembly from the brake arm.
6. Install a new pedal and park brake lock assembly, following steps 4
through 5 in reverse order. (Substituting the word install for remove in
steps 4 and 5.)
In the following procedure, you will be told how to check the Park Brake Lock for
Wear.
1. After removing the park brake lock, inspect the points of the notches
on the park brake lock.
2. If they are broken or worn, replace the assembly with a new one as
instructed above.
Wear Limits:
If you apply the park brake lock and it does not catch or slips easily it must be
replaced.
Press on the lower half of the pedal if the park brake lock engages with little
effort on the upper most notch. Check the linkage adjustments and adjust as
needed.
Always use new locknuts and bolts. Locknuts and bolts become
less effective if used more than once. If the locknuts or bolts
holding the brake to the drive come loose, serious injury may
occur.
