What parking brake condition is required when performing brake wear checks?

Explanation:
Engaging the parking brake during brake wear checks is essential because it locks the wheels and applies a known load to the braking system. This stability ensures that wear readings reflect the brakes under normal operating conditions and prevents movement that could skew measurements or create a safety risk. If the parking brake isn’t set, the wheel could turn and make wear assessments unreliable. Toggling isn’t a stable or standard condition for this check, since it doesn’t provide the required fixed load. So, the parking brake should be set.
