The LiftMaster 10-10354 Brake Release Arm is a genuine OEM replacement component used on select LiftMaster commercial door operators. This release arm interfaces with the operator’s brake assembly, allowing authorized personnel to mechanically disengage the brake for emergency manual operation or service procedures. Replacing a worn or damaged release arm helps restore reliable brake release action so the door can be moved by hand chain or manual method during a power outage or maintenance.
As a mechanical part, no programming is required after installation. Procedures vary by operator model; a qualified door systems technician should isolate power, follow lockout/tagout practices, access the brake housing, transfer the release linkage, and verify brake adjustment per the operator service manual before returning the unit to service. The 10-10354 designation should be matched to your operator’s parts breakdown to confirm compatibility with specific LiftMaster commercial jackshaft or hoist models. For safety and code compliance, test braking performance and entrapment protection after installation.
