How to Adjust a Parking Brake for a Clark Forklift

Adjusting a parking brake on the Clark forklift is a job you can do in just a few minutes with some basic tools. The parking brake lever is attached to a cable inside the operator compartment. The lever can be loosened or tightened with a nut on the cable. Occasionally, the parking brake cable will loosen from wear and the vibration of the forklift, requiring that it be adjusted.

Step 1

Place a wood block behind the rear wheel of the Clark forklift to prevent it from moving while you are attempting to adjust the parking brake. Locate the parking brake handle next to the steering column, and open the operator compartment cover.

Step 2

Determine whether the parking brake cable is too loose or too tight by pulling up on the cable. If it moves more than a 1/2 inch, the cable needs to be tightened; if it moves less than a 1/4 inch, it needs to be loosened.

Step 3

Turn the nut on the cable with an open-end wrench. Turn the nut clockwise a half-turn at a time to tighten the brake and counterclockwise a half-turn at a time to loosen the brake.

Step 4

Activate the parking brake lever between each adjustment to determine how much adjustment is needed. Proper adjustment will cause the parking brake cable to move between a 1/4 and 1/2 inch.

Step 5

Close the operator compartment cover.
