The guideline states that park brake levers must not move to the forward position on their own during brake release.

• A. True
• B. False
• C. Not applicable
• D. Unknown

Answer: (A)

Movement of the park brake lever during brake release should not occur on its own. The lever is designed to stay in its current position and only move when the operator actively releases or applies the parking brake. If the lever advances forward without intervention, it signals a fault in the release mechanism or hydraulic control—potentially causing unintended braking or failure to fully release the brake when commanded. In C-17 tow operations, this safety check ensures that braking controls remain predictable and under clear operator control. Therefore, the statement is true: park brake levers must not move to the forward position on their own during brake release. If such movement is observed, stop and inspect the release valves, linkage, springs, and related hydraulic components per the maintenance procedures before continuing.
