I was assigned to replace a Main Landing Gear (MLG) brake on a B747-400 aircraft on the North Ramp with Mechanic Y. We printed the Maintenance Manual for brake replacement and the [associated] Task Document [that included sign-offs] for the brake change. After about one-half hour my partner was reassigned a different job and I was working alone. I than got two other mechanics to help and then; they were also reassigned. I was then working by myself and several supervisors were rushing me to complete the job as the aircraft was a departure for picking up passengers for an upcoming International Summit. I completed the brake change per the paperwork and nowhere in the paperwork or the Task Document (T/D) does it state to have the torque arm inspected by an Inspector. I was informed by Management that I failed to flag the job for Inspection per the new [expanded] Inspection Required Checklist. Nowhere in the paperwork for this job does it say to have the [brake] torque rod inspected; We; at Legacy Carrier X; have never had to have an Inspector check a Main Landing Gear brake change and our Legacy Air Carrier's RII list does not show this as an Inspection item. The training I received from our [merged] company about the new expanded Inspections lists and my responsibilities was inadequate. The training was rushed to us so the [merged] company could get a Single Operating Certificate (SOC). Most Legacy Air Carrier X employees were told by Management to read approximately 20-30 Engineering documents that were delinquent [outdated]. This policy of requiring the Mechanic to know every item on the new Inspections list was poorly communicated to us.
A Line Mechanic reports a new; expanded Inspection Required Checklist for maintenance work accomplished that was implemented after their merger; was poorly communicated by Management and contributed to his missing an inspection item on a B747-400 brake change.
